ProLock quick-release brackets are precision machined from billet aluminum. Available for our 1 lb., 1.4 lb. and 2.5 lb. extinguishers, they provide an exceptionally secure, rattle-free mounting solution for demanding vehicle applications. A key design element is the lever-action locking/release mechanism that is easier to actuate than pull-pin designs in some installations where space is tight. With both flat surface and roll bar options, ProLock brackets will keep your extinguisher secure whether you are hitting the track or blazing your own path off-road! One-year limited warranty.
