Sargent & Greenleaf 8077-108 – Frequently Asked Questions
1) Will a Sargent & Greenleaf 8077AD padlock fit the hasp on my file cabinet locking bar?
The 8077AD is built specifically for securing file cabinet locking bars, and it meets federal specification FF-P-110J. The shackle is 5/16 inch in diameter with 7/8 inch of clearance, and the hasp opening it wants is 3/8 inch (9.5mm). Measure the slot in your locking bar: if the opening is at least 3/8 inch and the bar stack is under 7/8 inch thick, the shackle closes. The lock body is 2-3/8 inches wide, so allow that much room around the hasp.
2) Can I change the combination on the S&G 8077AD myself, or does it come preset?
You can reset it in the field. The 8077AD ships with a change key, and the combination is reset at the lock itself, no disassembly and no locksmith. It's a resettable dial combination lock, so a facility can rotate combinations when staff changes without swapping hardware. The dial supports 125,000 unique combinations.
3) Is the S&G 8077AD the right padlock for a gate, locker, or shed?
It isn't the one to reach for there. The 8077AD is a government-spec lock built to FF-P-110J for file cabinet locking bars, and its geometry reflects that: only 7/8 inch of shackle clearance and a 3/8 inch hasp opening. That won't pass through a gate chain, a hasp staple, or most locker loops. For general-purpose padlocking, look for a padlock with a long shackle and a wider throat. Buy the 8077AD when the requirement is a document security cabinet and the spec on the drawing says FF-P-110J.
4) What makes the 8077AD a high-security padlock rather than a standard combination lock?
Two things beyond the dial. First, it's a combination padlock designed to resist surreptitious entry and tampering, which is what the FF-P-110J federal spec covers. Second, three separate parts of the lock carry unique serial numbers. If someone breaks the lock and substitutes a replacement part to hide the entry, the mismatched serials give it away on inspection. That audit trail is the point for anyone doing periodic security checks on cabinets.
5) Is the 8077AD a keyed padlock or a dial combination padlock?
Dial combination, no key to carry for daily use. It's a round combination lock with a black dial. The only key involved is the change key that comes with it, and that's used solely to set a new combination, not to open the lock. For a facility that doesn't want to manage a key system across a room full of cabinets, that's the trade: users memorize a combination instead.
6) Will one 8077AD padlock work across a bank of file cabinets in the same office?
Yes, as long as each cabinet uses the same style of locking bar. The 8077AD is dimensionally consistent, 2-3/8 inch body, 5/16 inch shackle, 7/8 inch clearance, 3/8 inch hasp opening, so a set of them standardizes across a row of cabinets. Because each one is individually resettable at the lock with its own change key, you can run one shared combination across the bank or a different combination per cabinet, whichever your access policy calls for.
7) How tough is the shackle on the S&G 8077 padlock?
Case hardened steel, 5/16 inch in diameter. The hardening matters more than the diameter on a lock this size, it's what resists a bolt cutter bite and a hacksaw. The 7/8 inch clearance keeps the exposed shackle short, so there isn't much to get a tool onto in the first place.
8) What is the difference between the 8077AD and the plain 8077 part number?
8077AD is the model designation and 8077 is the series it belongs to. The specific part covered here is 8077-108: padlock type, black dial, case hardened steel shackle, sized for a 3/8 inch (9.5mm) hasp opening. If you are ordering against a spec sheet or matching what's already on the cabinets, 8077-108 is the number to quote.
