The MR-X is our heaviest-duty mending reinforcer, built for joists that are broken, severed, or badly cracked.

All Joist Repair testing is done on worst case conditions. In the case of the MR-X that meant that test samples were completely through in the center span as well as a second cut through on one end of the joist with MR-X's used to reconnect both splits. When pushed to failure, the joists broke in the wood outside the plates, not at the repair.

The MR-X plate is 23-3/4" long and wraps under the bottom of the joist for added strength. It is 10-gauge G90 galvanized steel, engineered and Patent Pending.

Minor crack or knots, with no access below the joist? The MR-S mounts on one side only, at a lower cost.

1 MR-X plate (2x6, 2x8, 2x10), or 2 plates that lock together with T connectors (2x12)
Matched quantity of 1/4" x 1-1/2" structural T25 Torx fasteners
1 T25 Torx driver
1 5/32" drill bit for pilot holes
