Picking a lock in the wrong direction can be frustrating. Bumping the wrong way can be even worse. Longer pins will capture the bump key, making it impossible to insert a plug spinner. So it's back to the shear line and start bumping again, right? Not with the Peterson Over-The-Key Spinner Tip. Mounting to the incredible Peterson Plug spinner, this tip fits over the bow of virtually any bump key. No need to insert another tip in the key way, the Bump Key Is the Spinner Tip! Take a tip from the Peterson and get over on your bump key!
