Dormakaba 75323626LH BTS80 Offset Bottom Arm Satin Chrome

Product Description

The DORMAKABA 75323626LH is a heavy-duty offset bottom arm assembly for the BTS80 series floor-concealed door closer system. The arm connects the door closer body to the door bottom, transmitting closing force through the offset pivot geometry required for specific door and frame configurations. It ships with a cover cap that conceals the mounting hardware for a finished appearance. This component is installed by commercial door hardware technicians and locksmiths as part of a complete floor-closer installation in commercial or institutional entryways.

This offset bottom arm is suited for commercial applications where the BTS80 floor-concealed closer is specified. The offset design accommodates door and frame conditions that a standard straight arm cannot address, making it appropriate for heavy-traffic doors in office buildings, healthcare facilities, schools, and similar commercial environments. The 626 finish designation corresponds to Satin Chrome (US26D), a widely specified architectural hardware finish that coordinates with standard commercial door hardware.

Key Features

• Offset geometry accommodates specific door-to-frame clearance conditions in BTS80 floor closer installations
• Heavy-duty construction rated for high-cycle commercial door applications
• Includes cover cap to conceal mounting hardware for a clean finished look
• 626/US26D Satin Chrome finish matches standard commercial architectural hardware specifications
• Designed as a direct component for the BTS80 series floor-concealed closer system

Compatibility

Designed for use with the DORMAKABA BTS80 series floor-concealed door closer system. Confirm arm geometry and closer model designation before ordering to ensure proper fitment within the specific installation.

Installation Notes

Installation of floor-concealed door closer components should be performed by a qualified commercial door hardware technician or licensed locksmith. The door and closer body must be fully depressurized and all associated hardware disengaged before replacing or installing the bottom arm. Refer to the BTS80 installation template and hardware schedule for correct arm orientation and fastener torque requirements specific to the job. Local building codes and accessibility standards such as ADA and ANSI A156.4 may govern closer performance requirements for the finished assembly.
