Master Lock 7KA Laminated Padlock Keyed Alike Set of 3

Product Description

The MASTER LOCK 7KA is a laminated steel padlock sold as a set of three, designed for heavy-duty security in commercial and industrial applications. The body measures 1-1/8 inches wide and is built from laminated steel layers bonded together for superior resistance to impact and physical attack. A 9/16-inch tall, 3/16-inch diameter standard steel shackle provides secure closure across standard hasps and hardware. Dual locking levers engage the shackle on both sides to resist prying and cutting attempts. The non-rekeyable 4-pin W7 cylinder is engineered to resist picking and unauthorized key duplication.

These padlocks are sold as a keyed-alike set, meaning all three locks operate with the same key. This makes the 7KA well suited for facilities that need consistent key control across multiple access points without carrying separate keys. They are commonly deployed on security gates, fences, tool cribs, vending machines, storefront business gates, and other commercial or industrial entry points where reliable, repeatable access control is required. Keyed-alike sets can also be ordered to match other locks equipped with the W7 cylinder.

Key Features

Compatibility

The 7KA keyed-alike system is compatible with other MASTER LOCK padlocks using the W7 cylinder, allowing multiple locks to be ordered or matched to operate on the same key.

Installation Notes

Installation requires no tools beyond proper hasp or locking hardware already in place on the gate, door, or enclosure. Verify that the shackle clearance and hasp slot dimensions are compatible with the 3/16-inch shackle diameter before installation. Inspect the locking hardware mounting for secure attachment to the structure before relying on the padlock for security. No electrical shutoff or licensed trade credential is typically required for padlock installation.
