Dorma PHX03 Vertical Latch with Strike Silver 3501422031001

Product Overview

Dorma PHX03 vertical locking latch and strike set is designed for industrial and commercial environments requiring secure multi-point locking on doors. The PHX03 components are installed at the top and bottom of the door leaf, locking vertically into the floor and head of the frame, and are certified for use with fire-resistant and smoke-control doors.

A notable feature of the PHX03 is its steel construction for both latch and strikes, which ensures durability and security in high-traffic and demanding settings. For projects specifying 3-point surface-mounted panic lever systems, this set is particularly suited, as it fulfills compliance needs for fire and smoke door certifications in office complexes, retail spaces, and institutional buildings.
