Built for Utility and Industrial Gates
This padlock is designed to secure utility meters, substations, cable boxes, and construction equipment. It also fits storefront and business gates where keyless access is preferred. The bottom-mounted dials allow operation in tight mounting positions. It serves crews who need shared entry without managing physical keys.
Four Dials for Resettable Codes
The lock uses four dials to create a user-set combination that can be changed as personnel or access needs shift. No control key registration is required, so administration stays simple. It provides adequate security for general industrial enclosures and site equipment. High-security perimeters or regulated critical infrastructure may demand a different locking system.
Stainless Steel Body and Shackle
Both the lock body and the shackle are made from stainless steel to resist corrosion in outdoor and industrial environments. The shackle measures 5/16 in. in diameter with a 1 1/16 in. clearance height. A single bumper helps protect the body finish during daily use. The 15/16 in. body thickness and 2 1/4 in. width suit standard hasps and chains.

Questions about this item
Will the 5/16 in stainless-steel shackle fit the existing hasp on my utility meter box?
The shackle diameter is 5/16 in and the clearance height is 1 1/16 in; measure your hasp opening and staple gap to confirm they accept those dimensions before installing.
How can I verify the four-dial mechanism is set correctly after I choose a new code?
After resetting the combination, scramble the dials, then re-enter your code and pull the shackle — smooth release confirms the new sequence is engaged.
Does the package include any mounting brackets or a control key for the lock body?
The box contains only the padlock itself; no brackets, control key or additional hardware are supplied, so any mounting hardware must be sourced separately.
