Von Duprin 248L-4 Vertical Rod Bottom Strike, 22/33A/35A/98/9927, 98/9957 Standard Panic Strike

The Von Duprin 248L-4 is a commercial-grade, surface-mounted bottom strike designed to optimize the latching performance of vertical rod exit devices. As the industry-standard panic strike for standard openings, it serves as the secure floor-level engagement point for the bottom bolt of the exit bar assembly.

Engineered primarily for applications featuring a flat threshold or a finished floor, this strike provides a precise 3/8" projection to ensure tight latching without creating an excessive trip hazard. Built from heavy-duty metal to withstand constant foot traffic and heavy door impacts, the 248L-4 is an essential component for maintaining building security, smooth door operation, and life-safety code compliance on high-use commercial doors.
