The 28NR Joist Notch Repair Kit is an IRC Code Approved structural steel plate designed to restore the strength of Floor Joists that have been compromised due to over cut notches either at the top or bottom of the Joist. Notch size is 3" deep and 5" wide, allowing for the custom installation of water, drain, or electrical. The 28NR is the perfect companion to offset toilet flange that may be required where toilet drains are set to close to a Joist. All fasteners and driver tip are included. Need a Hole Reinforcer instead?
