These brake-loaded castors are designed to provide an adaptable and robust mobile castor base for your office chair. The castors feature a locking mechanism that engages when weight is applied to the seat, preventing the chair from moving. This provides added stability and safety, particularly when getting in and out of the chair. Once the pressure is lifted off the seat, the castors are released, allowing for smooth and effortless mobility. These brake-loaded castors are ideal for use in busy office environments, where safety and maneuverability are paramount. They are also durable and long-lasting, ensuring that your office chair remains reliable and functional for years to come.
