CRL Wood Mount L-Angle Kit is manufactured for use with CRL Heavy Aluminum Base Shoes. When screwed to structurally sound wood beams, they provide an attachment point using our pre-drilled Base Shoes and our Cat. No. SHCS12X34 Stainless Steel Socket Head Cap Screws. A favorite technique is to attach the Wood Mount L-Angle Kit to the Base Shoe, set it in the proper position, and then screw it to the wood substrate. L-Angle Kits are made of mild steel with a 1/2"-13 tapped hole, and then zinc plated. Each Kit contains 10 L-Angles plus 80 wood screws.
