The DRX Modular Door Rail System is designed to give glass temperers and glazing contractors greater control over when, where, and how door rails are installed, adjusted, and updated. It features independent side covers and end caps that can be easily installed or replaced without having to remove the door from the pivot. The system also features 10-1/2” length rail bodies that can be moved along the glass to accommodate standard or custom door lengths. Because of this, they can be stocked to virtually eliminate lead times for installing custom glass doors. Making adjustments to the glass door after it is installed in the pivot is easier. A proprietary jaw-lock mechanism built into the Rail Bodies is able to withstand a pull force test of up to 1,300 pounds. The system accepts an assortment of hardware such, as tubular panic devices, deadbolt handles, and floor locks.
