Master Lock Co 120Q Solid Brass Padlock 4 Pack Keyed Alike

Product Description

The MASTER LOCK CO 120Q is a solid brass padlock sold in a 4-pack configuration with keyed-alike cylinders, making it a practical choice for applications where a single key must operate multiple locks. The body measures 3/4 inches and features a 4-pin tumbler locking mechanism housed in a solid brass body for corrosion resistance. The shackle is 7/16 inches tall with a 5/32-inch diameter, suitable for light-duty hasps, cabinets, lockers, and storage applications. Licensed tradespeople and facility maintenance technicians commonly specify keyed-alike sets to reduce key ring clutter across multiple access points.

This padlock set is well suited for residential and light commercial applications where consistent key control across several locking points is required. Typical install scenarios include securing tool storage boxes, electrical panel enclosures, gate hasps, and chemical storage cabinets. The keyed-alike feature means all four locks in the pack operate from the same key blank, reducing the number of keys that need to be managed on a job site or in a facility.

Installation Notes

Installation requires no special tools — insert the shackle through the hasp or staple and press closed until the locking mechanism engages. Before installing on enclosures containing live electrical components, de-energize the circuit and follow applicable NFPA 70E lockout/tagout procedures. Verify hasp staple diameter is compatible with the 7/16-inch shackle before installation.
