What type of padlock is the “Hockey Puck”? As the name suggests it is shaped like a hockey puck. It is 2-7/8” wide by 1-1/2” thick. It has no visible shackle and is usually made of solid hardened steel. It comes with many types of lock cylinders and security levels. Most manufacturers stick to the basic size and construction materials, with the difference in the lock cylinders. More on this later.
A weak point in most padlocks is the shackle, which is the attacking point. Some shackles are cut very easily with bolt cutters. The Hockey Puck padlock was designed to combat this by not having a visible shackle to cut. It has an internal shackle that is operated by the lock cylinder. When the lock is opened it moves down and out, this moves the shackle to an open position. When the lock cylinder is closed or locked the shackle moves to a locked position. In this position the shackle will go through the holes of specially designed hasps.
Hasps designed for this type of padlock usually shrouds the padlock so that it can’t get attacked on the sides or get “wrenched”. These hasps are usually made of hardened steel and are designed for a specific application.

As I mentioned earlier in this article, the lock cylinder is the major difference between the designs of these padlocks. Most of the hockey puck padlocks are physically secure and very difficult to attack. The cylinder is the factor that makes the difference between the padlocks. As in all types of locks the cylinder defines the security level. To get a high security hockey puck padlock you should look for one that has a patented lock cylinder that provides key control.
Most of these padlocks come with a particular lock cylinder and it cannot be changed, so the security level can’t be changed. There is a new style patented hockey puck padlock on the market that allows the end user to change the lock cylinder. This is a unique design in that the end user can purchase a lock for a particular application at a particular security level, if the need arises to go to a higher security level, the end user can very easily change the lock cylinder. This Type of Hockey Puck Padlock is known as the “Universal PUCK Padlock”.
