GROOM 150/200 Door Closer Arm Hold-Open On/Off Compatible with Dorma TS 71/72/73V/83 Silver

Product Overview

The GROOM 150/200 arm with on/off hold-open function is designed for use with Dorma TS 71, TS 72, TS 73V, and TS 83 door closers in silver finish. Frequently specified in commercial and institutional buildings, it allows doors to remain open temporarily until the hold-open function is disengaged, reverting to standard closing operation. Installation is suitable for interior doors where controlled door movement is required under varying access conditions.

The primary differentiator for this arm is its integrated hold-open mechanism with manual release, which enables facility operators to selectively enable or disable the hold-open feature without removing the arm or modifying door hardware. This flexibility is critical for fire safety compliance and access management in schools, offices, and healthcare environments, making it ideal for bulk procurement in adaptive-use projects.
