The W4 Adjustable Joist Bracket fits a W4x13 I-Beam. When joists run perpendicular to the wall being repaired, the 8" adjustable joist bracket will transfer the load at the top of the wall brace to the side of the floor joists when used in conjunction with a wooden or steel strut. Over time the bracket can be adjusted to straighten the wall and maintain proper tension. Adjustments can be made by the property owner and requires no special training to complete. Coated with a High Performance Rust Preventive Semi-Gloss Black Paint.
