What is a Puck Lock?

To understand the PUCK lock, you need to check how it evolved. Padlocks have been securing everything from storage units to tackle boxes for as long as anyone one of us can remember. One thing common to the traditional looking padlocks is the shackle. The shackle comes in many different lengths and widths depending on the padlock body size and what this is locking up.

You wouldn’t put a padlock with a 2-inch body and a 3/8 inch shackle on a tackle box, that would weigh more than the tackle box itself. The PUCK lock has invented because the major attach point of any padlock is the shackle.

The smaller the shackle diameter is, the easier it is to cut. For larger shackles, a larger pair of bolt cutters are used. The second attack point is where the shackle enters into the padlock body. This point is attacked by using a hammer and hitting the body where the shackle enters it.

How does a Puck Lock work?

A locking system has a base, a receiver, a bolt assembly, and at least one link member. The bolt assembly has a bolt that slides through the link members and the base, and into the receiver. The bolt assembly has an endplate with a padlock tab that projects through a slot in a plate on the link member.

Each link member has another plate with a padlock tab that can projects through a slot in a plate on the base or a slot on an adjacent link member. The padlock tabs each have a padlock aperture for a padlock or a puck lock. Removal of a lock allows a user to slide the bolt out of the receiver.
