The stepped back version can accommodate some of the conventional padlock hasps without providing sufficient surface area beneath the padlock body.įor this article, we will discuss the Pacific Lock “Hockey-Puck” Padlocks that include the conventional industry standard 2-7/8” body width, and the SFIC and K-I-K/K-I-L models having the 3” body width. “Hockey-puck” padlock hasps are made of heavy gauge metal, designed to resist removal using a pry bar or similar tools. The conventional lock cylinder and SFIC are available in the larger 3” width body. Keying options for these hidden shackle padlocks range from the manufacturers’ six pin tumbler cylinder having a padlock keyway to conventional six pin tumbler K-I-K/K-I-L lock cylinders and small format interchangeable cores (SFIC). Note: The 3” wide body padlocks will not fit into hasps made for the 2-7/8” wide body padlocks. At this time, there are two standard widths available 2-7/8” and 3” wide bodies. When first introduced, the 2-7/8” “hockey-puck” padlock was equipped with a standard five pin tumbler padlock keyway lock cylinder. The “hockey-puck” body shape can accommodate different surfaces, having the standard option of a flat or stepped back. The diameter and position of the shackle eliminate many methods of unauthorized entry including pulling the cylinder, core or plug. In the locked condition, the shackle oval tip is 90 degrees out of position to the rectangular opening in the body. To lock the padlock once the shackle is in the closed position, the plug is rotated 90 degrees with the slot in the shackle rotating around the two hardened pins. The shackle tip enters the opening when the lock cylinder is in the unlocked condition. Hardened rods create the receptacle for the shackle tip. The body of the “hockey-puck” padlock has a machined circular opening at the top. The shackle tip is machined to an oval tip with a slot running the circumference. The rod style shackle rotates as the key is turned. This type of padlock uses a large diameter rod style of shackle compared to a conventional padlock shackle. Unlike a conventional padlock, the lock cylinder is almost always in the sideways or downward fixed position, making it more difficult to gain access to the keyway. This highly adaptable style of padlock is being used to secure standard padlock and hasp applications as well as vehicle doors, box truck roll up shutter style doors, trailer doors, trash bins and gates. “Hockey-puck” style padlocks have become very popular because of their mass, hidden shackle, keying options and the higher level of actual and perceived security.
