Commercial steel padlock for keyed-alike security
This laminated steel padlock uses a five-pin Master K81 keyway and opens with key number 10R40. It is sold keyed alike so multiple locks share one key. The rectangular body measures 1 3/4 inches high by 1 3/4 inches wide and 7/8 inch thick with a silver finish. Two bumpers protect the lock body during daily use.
Hardened steel shackle resists cutting under
The 5/16-inch diameter steel shackle provides 15/16 inch of vertical clearance and 3/4 inch of horizontal clearance. High-security rating indicates resistance to physical attack over time. No weather-resistant coating is applied, so prolonged outdoor exposure may cause surface corrosion. The lock is not rekeyable and has no interchangeable core.
Verify shackle dimensions match your hasp
The 5/16-inch shackle diameter must fit the attachment point without forcing. Keyed-alike configuration means every lock in the set uses the same key number 10R40. No control key registration is required. Buyers who need individual keying or a weatherproof finish should choose a different model.

Questions about this item
How much power does the 5-pin cylinder draw when the padlock stays locked all day?
The Master Lock padlock is a mechanical device with no electrical components, so it draws zero power while locked or unlocked.
What existing key must I already own for the K81 keyway to operate this padlock?
The padlock opens with key number 10R40; any key cut to that code and the Master K81 keyway will operate it.
Will the 15/16 in shackle height clear the same hasp used by my older Master Lock models?
The shackle measures 15/16 in high, 3/4 in wide and 5/16 in diameter — compare those dimensions to your existing hasp clearance.
