Reinforcing rib for very high bending strength: each bracket is pressed from 2.5mm steel with a rib across the corner, and that rib is what gives the bracket its very high bending strength, for load-bearing 90 degree timber joints that have to carry load and stay square. Galvanised steel with a zinc coating of 275 g/m² on both sides, for high corrosion resistance; fire reaction class A1, non-combustible. Size 105 x 105 x 90mm: arms (A and B) 105mm (4.13in) and 105mm (4.13in), width (C) 90mm (3.54in), 2.5mm thick, holes 36 × ø5, 2 × ø14 (mm). This listing is a pack of 5 brackets. Load data: 35.2 kN, characteristic maximum load in compression, from tests, for a complete joint with two brackets (half the value per bracket); timber density 350kg/m³. CE marked under a European Technical Assessment. Wide, well-spaced hole pattern: fix with nails, wood screws, bolts or concrete anchors, in a standard detail or a joint designed from scratch. Also known as corner braces, corner brackets for wood, L brackets or 90 degree brackets: for post to beam, joist to beam, wall framing and frame corners; the 70mm to 105mm sizes also join timber to concrete or to steel.
