Von Duprin 248L4 Vertical Bottom Rod Strike

Product Description

The VON DUPRIN 248L4 is a vertical bottom rod strike designed for use with vertical rod exit device assemblies in commercial door applications. This strike provides the floor-mounted catch point that secures the bottom rod of a vertical rod panic hardware set, keeping the door positively latched when closed. At 2.5 inches in length, 1 inch in width, and 0.5 inches in height, it is a compact, low-profile component that installs flush with or recessed into the floor. Licensed locksmiths, door hardware specialists, and commercial contractors are the primary trades that specify and install this type of hardware.

The 248L4 is suited for commercial and institutional door openings where vertical rod exit devices are mounted to control egress. Typical applications include interior stairwell doors, corridor doors, and other openings requiring positive latching at both the top and bottom of the door leaf. This strike is the bottom-rod component that pairs with vertical rod panic hardware in double-door or single-door configurations where floor strike engagement is required.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial locksmith familiar with exit device hardware and applicable building codes. Before servicing or replacing the strike, ensure the door is propped open and the exit device is disengaged. The strike is typically mortised or surface-mounted to the floor substrate, and proper alignment with the bottom rod is critical to ensure reliable latching. Verify compliance with local life-safety and egress codes before completing the installation.
