Product Details
The Master Lock No. 1KA-2031 is a commercial-grade laminated steel padlock built for demanding job site and industrial applications. The 1-3/4 in (44mm) reinforced laminated steel body delivers superior strength and resistance to prying and drilling. A 15/16 in tall, 5/16 in diameter hardened steel shackle provides excellent cut resistance, while dual ball bearing locking maximizes pry resistance. Keyed alike functionality allows multiple locks to be operated by the same key, ideal for contractors and site managers who need consistent access control across a job site. The non-rekeyable 4-pin W1 cylinder is engineered to resist picking and unauthorized access.
