  • Diamond Plate Threshold for Roll Up Door 5

    Posted by Guy Cashman on 23rd Mar 2025

    The diamond plate threshold is a must have for the elimination of water intrusion under a roll-up door. It's unique design features a formed lip on the rear of the threshold that precludes water from migrating onto the interior floor. The threshold appears to be stainless with a non-slip tread and came precut to 72" for my application (several sizes are available). I needed to trim 1/2" off of either side (length), easily done with a hacksaw. The width was a perfect fit. The previous installation was a piece of angle aluminum. Water intrusion was damaging to the floor, which needed replacement.
