Sargent & Greenleaf 6741-002 Economy Combo Lock

The combination is user changeable. The 6741-002 uses a key-changeable wheel design, so with the change key you reset the combination on the lock itself rather than replacing it. For an MRO or property team that is the difference between a lock you can rotate after staff turnover and one you scrap when someone leaves.

There is an internal relock trigger. If the lock body is attacked and the case is compromised, the relock trigger fires and holds the bolt in the locked position instead of letting the container open. That is the security feature that separates a safe lock from an ordinary combination padlock mechanism.

Standard left-right-left dialing sequence, the same pattern anyone who has run a mechanical safe dial already knows. The 6741-002 uses a die cast push-pull lever and is built with wider dialing tolerances, so a dial number that lands slightly off center still retracts the bolt. That matters on shared openings, a property manager or facility staff turning the dial without much practice gets in without repeated re-dialing.

Order it under MPN YBLED60/PCT. It ships as the economy combination lock configuration, mechanical dial rather than electronic keypad, so specify it by that part number when matching an existing S&G mechanical installation.

A mechanical dial like the 6741-002 has no batteries and no electronics to fail, so it keeps working through power loss and long periods of no use, and it is the right choice where a container sits unattended for months or where batteries are a maintenance burden. An electronic keypad wins where you need multiple user codes, audit trail, or fast entry many times a day. If the container currently wears an S&G mechanical dial and the goal is like-for-like replacement without redrilling the door, the mechanical route is the one that keeps the existing prep.
