Brake kits contain the necessary parts for installing brakes on compatible casters. When they're engaged, the brakes prevent caster wheels from rolling to keep carts, furniture, and other equipment stationary during use. This helps improve the stability of the equipment during use and can prevent injuries caused by unexpected rolling. Brakes do not prevent swivel casters from swiveling.

Total-lock kits include the required parts for installing total locks on compatible casters. Total locks prevent casters from both swiveling and rolling when they're engaged. They are used on workstations, scaffolding, work platforms, and similar equipment to completely immobilize the equipment so it remains stable while people are using or working on it. This can help prevent injuries caused by the casters unexpectedly rolling or turning.
