Master Lock Co 1KALF-2126 Laminated Padlock Keyed Alike

Product Description

The MASTER LOCK CO 1KALF-2126 is a 1-3/4 inch laminated padlock built for general security applications across trade and commercial job sites. It features a 1-1/2 inch long shackle with a 5/16 inch diameter, offering clearance for heavier hasps, chains, and lockout-tagout devices. The laminated steel body construction provides durability against impact and weather exposure. This unit is keyed alike to key number 2126, making it a practical choice for installations requiring multiple locks operated by a single key. Compatible key blanks include Master Lock K1BOX and Ilco M1 TV 320-952.

This padlock is suited for securing equipment panels, gate hasps, storage units, and lockout-tagout points in residential, commercial, and light industrial settings. The keyed-alike designation makes it especially useful for facilities managers, electricians, and maintenance crews who manage multiple access points and need one key to operate several locks across a job site or building.

Installation Notes

Installation requires no special tools beyond the supplied key. Before applying this lock to electrical panels or energy isolation points, ensure all equipment is fully de-energized and lockout-tagout procedures comply with OSHA 29 CFR 1910.147 and applicable site safety plans. Verify hasp or staple clearance accommodates the 5/16 inch shackle diameter before installation. Do not force the shackle into undersized hardware, as this can damage the locking mechanism.
