French cleat for heavy artwork: when a large painting needs one, and how it is specified
A French cleat is a pair of bevelled rails (most often cut at 45 degrees), one on the wall and one on the back of the work, that lock together under its own weight. It is worth specifying when a painting is wide or heavy enough that a wire or single hook would let it tilt or load one point. Weight and wall decide, not size alone.
How a cleat works, and where it earns its place
Genesis of Flame (2025) is mixed media on canvas, 120 x 200 cm (47 x 79 in): a vivid red nucleus ignites from a deep black void and releases waves of silver, copper and rose fragments, with gloss set against matte. A work of that height and width is where the hanging method stops being a detail.
Colorado Art Services, a professional art-hanging firm, describes the cleat as a pair of interlocking strips cut at an angle, most often 45 degrees. One strip is fixed to the wall and faces up and out from it; the matching strip is fixed to the back of the work and faces down and in. When the work is lowered into place the bevels seat together, and its own weight helps hold it. The same firm explains why heavier work asks for more than a wire: a wire-hung work is free to shift, sag and tilt, a single fastener concentrates force in one small section of wall, and wide or deep pieces act as levers. A cleat spreads the load along its length and keeps the work closer to the wall.
The installer is also plain about what a cleat is not. It is a choice about the whole wall system: the substrate, the fasteners and their spacing matter more than the rail, and a cleat does not replace good fastening, it only gives good fastening a better way to carry the load.
When a large painting needs one
The same installer reduces the decision to a few questions. What does the fully assembled piece weigh, including frame, backing and attached hardware, measured rather than guessed? What is the wall made of? Can the fixings reach structure? Does the back of the piece take a cleat cleanly, with the frame-side rail centred on a solid back rail or structural part? And does the owner need to adjust the position after hanging? A cleat trades easy repositioning for control, support and a flatter sit against the wall. Once engaged, the position is largely set.
The installer's rule is hardware rated for at least twice the weight it carries. Commercial cleat kits advertise capacities from about 100 lb to 300 lb or more, but the installer treats a printed rating as a ceiling for the rail alone and derates it for wall type, fastener pattern and how directly the load reaches structure.
The same source lists cases where a cleat is the wrong answer: rental walls where a multi-hole pattern means repairs, very light frames, gallery walls that change often, fragile antique frames, and frame geometry where the bevel cannot seat cleanly.
Here is the data the studio's record gives for three large works. Weight and hanging hardware are not in it for any of them.
| Work | Year | Medium (as declared) | Dimensions | Archive ID | Weight and hardware on the back |
|---|---|---|---|---|---|
| Genesis of Flame | 2025 | Mixed media on canvas (acrylic, metallic pigment, high-gloss and matte finish) | 120 x 200 cm (47 x 79 in) | AP-HOC-2025-001 | Not published; ask the studio |
| Silent Interval | 2026 | Mixed media with acrylic on canvas | 120 x 160 cm (47.2 x 63 in) | AP-MAS-2026-003 | Not published; ask the studio |
| Amber Strata | 2026 | Mixed media with acrylic on canvas | 150 x 100 cm (59.1 x 39.4 in) | AP-TAE-2026-004 | Not published; ask the studio |
Most of the studio's works ship unframed with finished gallery edges, and framing or float-mount can be arranged at the buyer's request. What the back of a given work can take is therefore a question to settle with the studio before a frame-side rail is chosen, not something a specification should assume.
How it is specified: the wall first, the rail second
The installer's order of work puts the wall before the hardware: identify the wall (drywall, plaster, brick, poured concrete, block or wood backing), check whether the fixings can reach structure, and only then choose the cleat. Buying the cleat first and finding out afterwards that the wall cannot take its fasteners is the mistake that sequence prevents. This page does not repeat the fixing detail for each wall; it is covered in drywall, plaster and concrete or masonry.
Two geometric points follow from the installer's guidance. First, the installer describes a long wall rail screwed into several studs, and gives stud spacing as almost always 16 or 24 inches (about 41 or 61 cm) centre to centre. Across the 120 cm width of Genesis of Flame or Silent Interval that is about three 16-inch bays or two 24-inch bays. That figure describes North American stud framing; in a masonry wall the substrate sets the fixing, not the stud grid.
Second, both rails must be level, because a cleat holds a work rigidly and shows any error across its full width. The installer advises marking a full reference line before drilling, test-fitting before the final hang, and lowering the work slowly until the bevels engage.
Orientation. Genesis of Flame has no fixed top or bottom: it can be hung either way up, at the buyer's choice. A frame-side rail is fixed to one edge of the back, so for a work that can go either way up, which way up is settled before the rail is fixed.
Does a cleat change the hanging height?
It changes when the height is decided, not the convention behind it. A wire can be adjusted on the wall; an engaged cleat largely cannot, so the height has to be computed before the wall rail goes up. The gallery convention that Park West cites is a centre line at 57 inches (about 145 cm) from the floor, which the installer treats as a starting point: a room with very high ceilings may call for a higher centre, and above a sofa or console the installer suggests the bottom edge sit 6 to 8 inches (about 15 to 20 cm) above the furniture. The method is set out in how high to hang a painting.
A worked example, as arithmetic and not as a studio specification: with Genesis of Flame, 200 cm high, centred at 145 cm, the bottom edge is at 45 cm and the top edge at 245 cm. Where the wall rail then sits depends on the measured distance from the work's top edge to its frame-side rail and on the hardware's own instructions, neither of which is in the studio's record. The installer suggests testing the placement with a paper template of the work's outline, taped to the wall with painter's tape, before any hole is drilled.

For those acquiring: documents, installation and shipping
Documents. Every acquisition is direct from the artist and includes the original, unique painting; a signed Certificate of Authenticity carrying the full technical record and the internal Archive ID; a fiscal invoice or official receipt; an Artwork Acquisition Agreement covering transfer of ownership, copyright and image use; an artist dossier with biography, series context and technical record; conservation and care guidance; and professional packaging.
Installation. What the studio publishes on installation is guidance and coordination: installation guidance, including ideal hanging height and lighting, is available on request, and for architects and designers the studio coordinates hanging height, lighting angle and conservation guidance with the project team. The studio's pages do not state that it performs the cleat fixing, so treat that as the installer's or the project's scope, and confirm in writing what the studio can supply for a specific work.
Scale and light. Genesis of Flame is 120 cm wide and 200 cm high (47 x 79 in). The studio's care guidance asks for a dry, stable environment, away from direct sunlight, humidity and forced-air vents. A designer who provides reference photography of the space can ask for high-resolution previews of the work in it.
Shipping. The studio ships within Brazil and internationally. Shipping is quoted per destination and paid by the buyer, as are any import duties or taxes in the destination country; professional packaging is included and transit insurance is available. See the shipping page and the studio's page for architects and interior designers.
From the studio
From the studio: weight is the one number a drawing cannot take from the work
Alyne Perfeito is a Brazilian visual artist and trained architect based in Brasília. The studio describes her canvases as inhabited surfaces that negotiate the questions a building does, weight and air among them, in a painterly sense. Physical weight is the number this page cannot give: it is not in the studio's record for Genesis of Flame, Silent Interval or Amber Strata, so on a specification it belongs as "to be confirmed with the studio" until the studio supplies it.
Scale is the other half of the question. At 120 x 200 cm, Genesis of Flame reads on a tall wall of its own, which is where the hero visualisation places it; Amber Strata, at 150 x 100 cm, is the widest of the three and spans the most wall. Which way up Genesis of Flame is hung is the buyer's choice, and the cleat is the point at which that choice becomes physical.
Frequently asked
What is a French cleat and why is it used for large paintings?
A French cleat is two interlocking strips cut at an angle, most often 45 degrees: one fixed to the wall, the other to the back of the work. The work is lowered onto the wall strip and its own weight helps hold it. It spreads load along the rail rather than onto one hook, keeps the work close to the wall and resists tilt better than a wire.
Is a French cleat better than wire or D-rings for a heavy canvas?
Not in every case. An installer's comparison rates a cleat high for load and tilt resistance when mounted into structure, but low for adjustment after hanging. D-rings on two screws rate moderate to high for load and are easier to rehang. Wire is forgiving to install but lets a wide piece shift. The choice depends on weight, wall and how much repositioning is expected.
How do you fix a cleat to drywall, plaster or concrete?
Wall first, rail second: identify the wall, check whether the fixings can reach structure, then choose the cleat. In drywall that usually means spanning studs; in plaster, anchors chosen for the wall's condition; in concrete or masonry, masonry fasteners with proper embedment. This site covers each in its own guide, linked on this page, so the detail is not repeated here.
Who installs the cleat: the installer or the studio?
What the studio publishes on installation is guidance and coordination. It gives installation guidance on request, including hanging height and lighting, and coordinates hanging height, lighting angle and conservation guidance with the project team for architects and designers. Its pages do not state that it performs the cleat fixing, so treat that as the installer's or the project's scope and confirm with the studio what it can supply for a specific work.
Does the cleat change the hanging height calculation?
It changes when the height is fixed. An engaged cleat largely cannot be nudged, so the height is computed before the wall rail goes up. For Genesis of Flame, 200 cm high, a 145 cm centre puts the top edge at 245 cm; where the wall rail then sits depends on the measured distance to the work's frame-side rail and the hardware's instructions.
Does the work arrive with a cleat, and what does it weigh?
The studio's record does not state the weight of its works or the hanging hardware on the back, so neither should be assumed. Most works ship unframed with finished gallery edges; framing or float-mount can be arranged at the buyer's request. Ask the studio what the back of the specific work can take, and what it can supply, before specifying a frame-side rail.
