Many works arrive in my studio held only with nails in the frame. Nails may loosen or fall out, jeopardizing the painting, or split the wood of the frame or stretcher. Countersunk nails are difficult and risky to remove.
Paintings should be held in the frame without direct insertion of fasteners into the painting. Zinc-plated or brass offset clips are held over the back of the painting and screwed into the back of the frame. Offsets come in standard depths or may be custom shaped to profile. The depth required depends on the degree to which the painting projects from the back of the frame. Ideally, the edges of the painting are fully recessed and protected by the frame rebate.
