Using this tape measure holder is super easy. First, use the strong metal hook to quickly attach your tape measure to the holder. Then, use the belt clip to hook it onto your trousers, belt, or belt loop. Make sure your toolbelt is no wider than 3'' (75cm). You can also put your pen or pencil in the convenient holder. When not in use, keep it in a dry place. Avoid exposing it to sharp objects that could damage the polyester material. If it gets dirty, you can gently wipe it with a damp cloth. Remember, it has a 1-year manufacturer warranty, so if there are any issues, you can get it sorted out.
