Problems I was having before holstery was too bulky of bags and the temptation of overfilling them everytime I used a tool on a job. Then having no good way to hang them up in the back of the service van as they would usually fall and tumble around in the back and tools end up all thrown around inside the bag. With these magnetic mounts I stick them on the parts shelves inside the van and all the holstery pouches clip securely in place and eliminates all issues I used to have before I found this outstanding company!
