Master Lock 4150KA-41242 Brass Keyed Alike Padlock

Product Description

The MASTER LOCK 4150KA-41242 is a brass-body padlock designed for keyed-alike applications where multiple locks must operate on the same key. The brass body resists corrosion in general-purpose environments, making it suitable for use in mechanical rooms, storage facilities, utility access points, and similar trade settings. The shackle is steel construction measuring 9/32 inches in diameter with a 1-inch width and 15/16 inches of clearance. A 5-pin tumbler cylinder provides solid resistance against unauthorized entry. Weighing 0.42 pounds, this padlock is compact and straightforward to deploy across multi-lock installations where uniform keying is required.

This padlock is well-suited for commercial and light industrial applications where a technician or facilities professional needs a consistent key across several lock points. Common install scenarios include panel rooms, equipment enclosures, gate hasps, and storage cabinets. The keyed-alike configuration is particularly useful for HVAC, plumbing, and electrical contractors who manage multiple access points on a job site and need a single key to operate all locks. It is sold individually as a single unit.

Installation Notes

Installation requires no special tools beyond confirming hasp or staple dimensions match the shackle width and clearance of this padlock. When used in keyed-alike sets, verify all locks in the group share the same key code before deploying on secured access points. Inspect the shackle and body for damage before installation. Do not force the shackle closed if the hasp slot is undersized, as this can damage the locking mechanism.
