Get quoteThe Silver Small Four-Hole L-Bracket Corner Brace 38mm (SKU: L39) is the compact version of the 50mm series, offering equal 38×38mm arms (9mm wide), 0.6mm steel plate, and 4 × 4mm screw holes. Designed specifically for small picture frames, A4-size photo frames, and lightweight decorative boxes where the larger L37 or L38 would be disproportionate to the frame size.
The Silver Small Four-Hole L-Bracket Corner Brace 38mm fills the small-frame bracket niche with precision. Its 28mm inner step keeps the screw holes well within the frame arm material, while the 38mm total arm length ensures sufficient overlap at the corner for solid joint reinforcement without protruding beyond standard small-frame profiles.
Arms: 38mm × 38mm (equal) | Width: 9mm | Inner step: 28mm | Thickness: 0.6mm | Holes: 4 × 4mm | Finish: Zinc-plated steel | Screws: Not included.
The Silver Small Four-Hole L-Bracket Corner Brace 38mm is recommended for frames up to 30×40cm (A3 size), small shadow boxes, jewelry display boxes, and any lightweight wooden corner joint. For the version with screws included, see our L40 with screws. Shop compact L-brackets at Amazon’s small corner brace selection.
