Using the Klein 5461T Erection Wrench Holder is a breeze. First, just slide the cotton web tunnel loop over your belt. Make sure your belt is no wider than 2 inches so it fits properly. Once it's on the belt, you can place your erection wrenches or the adjustable head construction wrench (Cat. No. 3239) into the holder. It can hold up to two wrenches securely, so you always have them within reach. As for maintenance, keep it away from excessive moisture to prevent the leather from getting damaged. If it gets dirty, you can gently wipe it with a dry cloth. When not in use, store it in a dry place to make it last a long time.
