Silver Five-Hole Thick L-Bracket Corner Brace 72mm – Maximum Strength for Heavy Frames
The Silver Five-Hole Thick L-Bracket Corner Brace 72mm (SKU: L35) is the strongest standard flat L-bracket in the XKY Framing range. Machined from 1.2mm thick steel with a zinc-plated silver finish, it features a 72mm long arm, 57mm short arm (both 16mm wide), and 5 screw holes of 4mm diameter for maximum corner anchoring in picture frames, wooden furniture, and structural woodwork applications.
Why the Silver Five-Hole Thick L-Bracket Corner Brace 72mm Outperforms Standard Brackets
At 1.2mm plate thickness, the Silver Five-Hole Thick L-Bracket Corner Brace 72mm is triple the thickness of thinner 0.4mm brackets in the range. This rigidity prevents the bracket from bending under load, maintaining perfect 90-degree joint alignment even on heavy frames subject to handling and transport. The 5-hole design adds an extra mounting point vs standard 4-hole designs for additional pull-out resistance.
