Master Lock Co 1KA-2359 Laminated Steel Padlock

Product Description

The MASTER LOCK CO 1KA-2359 is a laminated steel padlock designed for securing equipment, gates, storage units, and service access points in commercial and light industrial environments. The body measures 1.75 inches wide and is constructed from layered steel laminations for impact resistance. The shackle is 5/16 inches in diameter with a 15/16-inch clearance length, making it suitable for standard hasps and chain links. This padlock ships keyed alike to key number 2359, allowing multiple locks to be operated by a single key — a practical setup for facilities managers, contractors, and service crews managing multiple access points.

This padlock is well suited for HVAC equipment enclosures, electrical panel cages, pump houses, pool equipment pads, and other trade-service applications where consistent key control across multiple locks is required. The keyed-alike configuration to key 2359 simplifies access management on job sites or facilities where several locks must operate on one key. Compatible key blanks include the Master Lock K1BOX or Ilco blank M1 TV 320-952 for field duplication. The unit is packaged individually and sold in a case quantity of 6.

Installation Notes

Installation requires no special tools — insert the shackle through the hasp or chain link and close until the locking mechanism engages. Inspect the hasp or anchor hardware for adequate load rating before securing. For outdoor or poolside applications, periodically lubricate the keyway and shackle with a dry lubricant to maintain smooth operation. Ensure the shackle clearance length of 15/16 inches is sufficient for the intended hasp jaw gap before installation.
