Using your Klein Tools 5417T Bull - Pin Holder is a breeze. First, simply attach it to your tool belt through the tunnel connection. Make sure your belt width is up to 3.5 inches (8.9 cm) to ensure a proper fit. Then, you can easily place your standard bull pins inside the holder. When you need a bull pin, just reach down to your belt. For maintenance, keep the leather clean. You can use a soft, dry cloth to wipe it down occasionally. Avoid exposing it to excessive moisture as this can damage the leather over time. Also, be careful when handling the rivets; don't try to force or bend them. With proper use and care, your bull - pin holder will last you a long time.
