The Boss Adjustable Arm Kit is a mechanical hardware assembly featuring high-impact polypropylene housing and a steel internal reinforcement plate. Technical schematics indicate a spring-loaded ratcheting system providing approximately 3 inches of vertical travel. The mounting plate utilizes a standard 40mm x 100mm 4-bolt spacing, allowing for integration with various task chair chassis outside of the Boss B210 ecosystem.
Material analysis identifies high-density foam padding that resists pitting and deformation over time. The design provides a positive-lock ratcheting mechanism to prevent accidental height drops under vertical load. However, the assembly does not include pivot or width adjustment capabilities, limiting it to a single axis of ergonomic movement.
Technical protocols for installation recommend the application of blue threadlocker to the M6 mounting bolts to prevent looseness caused by lateral torque over the device's lifespan. These units serve as a reliable height-adjustable interface for analog ergonomic setups.
The Boss arm kit is recommended as a structural replacement for fixed arms on compatible task chair frames.
This kit is categorized within custom chair components as an ergonomic upgrade module.
