BMH 1000 72/65/9 ST24 Mortise Lock Fire-Rated Stainless Steel Faceplate Left Hand

Product Overview

The BMH 1000 72/65/9 ST24 mortise lock is designed for use in fire-rated doors in commercial and public buildings. Featuring a 72 mm handle spacing and 65 mm backset, this lock is intended for installation in environments demanding fire resistance, such as stairwells and emergency exits. The lock faceplate is made of stainless steel, supporting use cases where corrosion resistance and durability are essential under frequent usage and potential exposure to cleaning agents.

A distinguishing feature of this lock is its 9 x 9 mm spindle ("orzech"), which requires the use of specialized fire-rated door handles, eliminating the risk of improper hardware pairing that could compromise fire door certification. This makes the BMH 1000 72/65/9 ST24 especially appropriate for fire door manufacturers, OEM procurement, and facility managers who must comply with fire safety standards and require guaranteed system compatibility.
