Bank Bag Pinlock
Pinlock function slider body with large hole affixed to the top of the slider body. When pull is in the down position, a small padlock or other locking device may be inserted through the hole, preventing the pull from being raised and therefore keeping the slider from moving on the zipper chain. Raising the pull disengages the locking pin and allows the slider to operate the zipper.
Applications: Any item that requires security and/or where the user does not want the unauthorized opening of the zipper.
