I installed it with a drill. Had a pair of these that lasted for years and believed in their quality so purchased again. You can always return. Then right when I was about to drop the dough, I had an Epiphany! Bonne qualité, simple dutilisation. You cant just order a size up and have them fit, they are VERY narrow. Stay away and buy something more reliable. I ordered a size small and have a 26" waist. 1 Virtuel que je trouve inutile et de mauvaise qualité. Good braided wire, but common.
