Dorma PHX03 Vertical Locking Latch Set Steel for Fire-Rated Panic Lever Silver

Product Overview

The Dorma PHX03 vertical locking latch set is engineered for integration into three-point surface-mounted panic levers. These latches are installed at the top and bottom edges of the door leaf, providing vertical locking into the floor and upper frame. It is suitable for commercial and institutional environments requiring multi-point security, particularly for doors specified as fire-rated or smoke-control.

Its compatibility with fire-rated and smoke-control doors is the key differentiator, eliminating project risk for specifiers and contractors mandated to meet strict safety requirements. This makes the PHX03 latch set particularly well-suited for bulk procurement in public facilities, schools, hospitals, and commercial buildings requiring certified emergency exit hardware.
