Hidden Shackle Padlocks, or more commonly known as Puck Locks are great for many industrial applications. From work vans and business gates, to trailers and vending machines the list goes on. American Lock & Master Lock have chosen to simplify both of their hidden shackle lines in 2017. Read below to learn which locks are still in production and what to do if your current lock was discontinued!

It’s important to remember that a simplified line does not mean that your options as a consumer will be limited. In fact key numbers, measurements, back geometry, and body material from discontinued items carry over seamlessly into the current line.

Follow the chart below to determine which active model lock will fit your application.

The reference guide speaks for itself and clearly illustrates all options and choices for replacement that are available to you. Please carefully look over all choices to ensure that your replacement lock is applicable for ALL important features for your application.
Any Keyed Alike, Master Keyed, Sets, or Edge Keys can translate into a new active model Puck Lock as well, if so desired. Continue reading below to learn how to identify the part #’s required to get the correct cylinder built into your new puck lock.

When ordering it’s important to note any specialty keyway requirements in the “order notes” section of your order to ensure that the transition is as smooth as can be. When unsure of the current cylinder, please provide the desired key number as well. This provides the highest success rate in getting you exactly what you need.
