Master Lock 105KA-48 Keyed Alike Steel Padlock

Product Description

The MASTER LOCK 105KA-48 is a warded cylinder padlock built for trade and industrial applications where keyed-alike convenience is required. The body and shackle are both constructed of steel, providing solid resistance to everyday wear in mechanical rooms, utility enclosures, and job-site lockout scenarios. At 1-1/8 inches wide, this is a compact padlock suited for light-duty hasps, electrical panels, and tool storage. The shackle measures 3/16 inches in diameter, 1/2 inches in height, and 1/2 inches in clearance width. It is keyed to key number A48, making it interchangeable with other locks in the same keyed-alike series for simplified key management across multiple lock points.

This padlock is well-suited for lockout/tagout (LOTO) programs in commercial and light industrial settings, as well as general security applications in residential and trade environments. HVAC techs, electricians, and plumbers commonly use compact warded padlocks to secure service panels, equipment cabinets, and hasp-equipped enclosures during maintenance. The keyed-alike configuration is particularly useful on job sites where a single key must operate several locks simultaneously, reducing the number of keys a technician carries in the field.

Installation Notes

Installation requires no tools beyond inserting the shackle through the hasp or staple and engaging the locking mechanism. When used in LOTO applications, verify the padlock meets site-specific lockout/tagout program requirements per OSHA 29 CFR 1910.147 before deployment. Do not force the shackle closed if the hasp opening does not accommodate the shackle diameter, as this can damage the locking mechanism. Confirm key compatibility with other locks in the keyed-alike series before placing the lock into service.
