Master Lock Universal Pin Keyed Padlock

A simple way to match your existing Master Lock key setup.

Works with Master Lock's universal pin keying system.

Product Overview:

If you need a keyed padlock that fits into an existing Master Lock setup, this one keeps the job plain and steady. The 4 pin cylinder gives you a firmer feel when you turn the key, and the steel body brings a tough, no fuss kind of presence. It is made for Master Lock's universal pin keying system, so you can match it to a customer's current key blank with the right punch tool. That is handy when you want one lock to slot into the day without extra drama. Picture the lock set in place, hear that clean click, and feel the little bit of relief that comes with getting it done right.

Key Features:

• Universal pin keying system Lets you match the lock to an existing customer key with the proper universal punch tool, which keeps the setup moving.
• 4 pin cylinder security The 4 pin tumbler setup helps resist picking, so the lock feels solid when you turn it.
• Steel laminated case Built with steel and a laminated case, it brings a sturdy, matter of fact feel to everyday use.
• Case hardened shackle Dual steel levers lock both sides of the shackle, giving you a tighter, more confident hold.
• Shackle clearance With 1-1/2 in. vertical clearance and 5/8 in. horizontal clearance, it gives you workable room where fit matters.
