It is so easy to install! Just put the nose of the impact gun into the boot first and push it down so the front housing is smoothly and tightly covered. This gives you plenty of play at the back to stretch the boot with your fingers and get it over the rear of the wrench.
Rather than have your tool wear down from dirt and scratches you can have these boots get nasty and then simply change it out for a new one. No harm done and it extends the life of the impact drastically.
It will protect your impact wrench from cracks and scratches with normal use，Further protection from unwanted contaminates that can affect tool performance.
