Von Duprin 283 Vertical Rod Top Strike Wood Frame

Product Description

The VON DUPRIN 283 is a vertical rod top strike designed for wood frame door applications in commercial and institutional buildings. It serves as the latch point for vertical rod exit device systems, capturing the top rod when the door is in the closed and latched position. The 283 is a precision-fit hardware component installed by commercial door and hardware technicians as part of a complete exit device assembly. Its compact profile — 2 inches in length, 1.5 inches in width, and 0.2 inches in height — allows for clean integration into wood frame door stops without significant modification to the frame.

This top strike is intended for use with vertical rod exit device systems installed on wood frame doors in commercial, institutional, and public assembly occupancies. Vertical rod systems route a top and bottom rod from a center crossbar to latching points at the head and floor of the door. The 283 provides the head-of-frame strike pocket that secures the top rod latch. It is sold individually as a replacement or new-installation component for facilities upgrading or maintaining their exit device hardware.

Compatibility

Designed as a top strike for vertical rod exit device systems installed on wood frame doors. Specific device compatibility should be verified against the exit device manufacturer documentation for the installed system.

Installation Notes

Installation is typically performed by a licensed commercial door hardware technician or locksmith. Before servicing any exit device component, ensure the door is secured in an open position and that the building access control or alarm system is placed in a service mode per the authority having jurisdiction. The strike should be positioned and fastened to align precisely with the top rod latch travel path; misalignment will cause rod binding or incomplete latching. Refer to local building and life safety codes, including applicable IBC egress requirements, when replacing exit hardware in occupied commercial facilities.
