ABUS 155/40 C – Frequently Asked Questions
1) Is the ABUS 155/40 a 3-digit or 4-digit combination lock?
Four digits on the 155/40. The smaller 155/20 and 155/30 in the same family use a 3-digit code. All of them let you set the code yourself and reset it later, which is what makes the 4-digit version workable for a property manager handing out locker or cash box codes that change with tenants.
2) Can I set my own combination on the ABUS 155/40, or does it come with a fixed code?
The code is individually resettable, so you set your own 4-digit combination and can change it whenever the person using it changes. That is the main reason to pick a combination padlock over a keyed one for lockers, tool cribs, or shared cabinets: no key control, no rekeying, no cylinder to pin.
3) Is the ABUS 155/40 combination padlock strong enough for outdoor gate or job site security?
No. The 155/40 is built for casual-theft protection on items of medium value or average theft risk, things like bags, suitcases, cash boxes, jewel cases, and lockers. It is a zinc die-cast body with a hardened steel shackle, 1-3/4 inches wide, and it is not the lock for a site gate or an exterior storage container. For that kind of exposure look at a solid-body keyed padlock such as the Medeco 521 G8R weather-tight padlock with a solid stainless steel body, or the Sargent 858 with a stainless steel shackle.
4) I need to lock a bike or a chain with a padlock. Will the ABUS 155/40 work?
It will not. The 155/40 shackle clears 49/64 inch horizontally and 1-1/32 inch vertically, which is not enough to close around a bike frame member or most security chain links. It is sized for locker latches, cases, and cabinet bars. For chain or heavier-staple work you need a padlock with a longer shackle, such as the Sargent 60-858-2 with a 2 inch stainless steel shackle.
5) What is the keyed alternative to the ABUS 155/40 combination padlock for a locker or cabinet that has to go on a master key system?
The ABUS 155/40 opens on an individually resettable 4-digit code, so there is no cylinder to key into a system. When the opening has to sit on a keyed system instead, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, which lets the core be interchanged with the rest of a facility's cores. The Sargent 758 is a key retaining padlock, meaning the key cannot be withdrawn while the lock is open, and the Sargent 858 is the non-key retaining version with a stainless steel shackle in a US4 satin brass finish. Choose key retaining when you want the key to stay captive at the open lock, non-key retaining when the user needs to walk away with the key.
6) The ABUS 155/40 has a 1/4 inch shackle. What padlock has a heavier shackle for a gate or exterior hasp?
The 155/40 shackle diameter is 1/4 inch and the body is 1-3/4 inch wide, sized for lockers, cases and cabinets. For a heavier shackle, the Medeco 5260 in the 52 Series uses a 7/16 inch shackle diameter in a brass body with M3 key technology and a satin chrome finish. The Schlage KS23D/KS23F brass padlock and the Medeco 54515G both use a 5/16 inch shackle, sitting between the two. Measure the hasp eye or chain link before choosing, since a larger shackle diameter will not pass through a hasp drilled for 1/4 inch.
7) Can the ABUS 155/40 be used outdoors on a yard gate or utility enclosure?
The 155/40 has a zinc die cast body with a hardened steel shackle and is described for bags, suitcases, jewel cases, cash boxes and lockers, which is indoor and carried use. For a weather exposed opening, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder so the cylinder is ordered to your keying. The Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and cylinder included, for sites that want an audit trail and scheduled access instead of a mechanical key.
8) Should I buy a combination padlock or a keyed padlock for my building's storage rooms?
It comes down to who has to open it. A combination lock like the ABUS 155/40 has no key to issue, lose, or collect, and the 4-digit code resets, so it suits lockers, cabinets, and anything a rotating group of people opens. A keyed padlock is the answer when you need the lock on the same key system as the rest of the building. If that is your situation, ZenSupply carries interchangeable-core and keyed options such as the Sargent 60-858-2 removable core padlock with a 2 inch stainless steel shackle, which takes the same core as the rest of a Sargent keyway, or the Schlage KS23D/KS23F brass padlock with a 5/16 inch shackle.
9) How wide is the ABUS 155/40 body, and will it hang up on a tight locker door?
The body measures 1-3/4 inches wide. On a locker or filing cabinet latch that sits in a recess, that width plus the dial rotation is what decides whether you can grip and turn it, so allow a couple of inches of open space around the latch. On flush cabinet hardware with almost no relief, a padlock this size will be awkward to dial even where the shackle passes through fine.
10) What is the ABUS 155/40 shackle made of, and will it corrode in a damp basement or parking garage?
The shackle is hardened steel and the body is zinc die-cast. Hardened steel resists cutting better than brass but it is not stainless, so a wet or salt-air location will eventually show rust. For consistently damp or exterior duty, a stainless or brass-bodied padlock is the better buy, for example the Medeco 5260 with a brass body and 7/16 inch shackle, or the Sargent 82-856 with a 2 by 2 inch brass case and stainless steel shackle.
11) Can I standardize a whole bank of employee lockers on the ABUS 155/40?
Yes, and the resettable 4-digit code is what makes it practical at volume: every lock is the same model 155/40 with the same 1/4 inch shackle, so they all fit the same latch, and you reset each code as staff turn over instead of managing keys. Buy them all as the 155/40 C to keep one shackle geometry across the bank. Bear in mind the protection level is casual theft and medium-value contents, so this is a locker room or break room answer, not a controlled-substance or tool-crib answer.
12) What is the difference between the ABUS 155/40 and the smaller 155/20 and 155/30?
Two things separate them. The 155/40 carries a 4-digit code where the 155/20 and 155/30 use 3 digits, and ABUS rates the 155/40 for goods of medium value or average theft risk while the two smaller sizes are rated for lesser-value goods at low theft risk. The 155/40 body is 1-3/4 inches wide with a 1/4 inch shackle. If you are locking a cash box or a locker with anything worth taking, the /40 is the one to specify.
13) Which padlock should be specified when a facility is standardizing on one high security key system across all its locks?
The ABUS 155/40 is a combination lock with an individually resettable 4-digit code, so it stands outside any key system by design and is issued by code rather than by key. Facilities standardizing on a single key platform normally pick a padlock in the same family as their cylinders: the Sargent 82-856 is a non-key retaining padlock in the KESO Series with a 2 inch by 2 inch brass case and a stainless steel shackle, the Medeco 5260 is in the 52 Series with M3 key technology, and the Sargent 60-858-2 accepts a removable core from the 758/858 Series. A combination lock and a keyed padlock can coexist on the same site, but only the keyed padlock is administered from the key cabinet.
14) Is the Schlage KS23D/KS23F a direct replacement for an ABUS 155/40?
They are not interchangeable in use. The ABUS 155/40 is a combination padlock opened by an individually resettable 4-digit code, with a 1/4 inch shackle diameter and a 1-3/4 inch body width. The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch shackle, opened by a key. Swapping to the Schlage means the shackle is a larger diameter and every user needs a key issued to them rather than a code; swapping the other way removes the lock from key control. Confirm the hasp opening accepts the larger shackle before substituting.
15) What is the difference between the Sargent 758 and the Sargent 858 when replacing a combination padlock on tenant storage?
Both are Sargent padlocks with a US4 satin brass finish, and the difference is key retention. The 758 is key retaining, so the key stays captive in the lock while the shackle is open, which suits storage cages and cabinets where a key left in an open lock would otherwise walk off. The 858 is non-key retaining with a stainless steel shackle, so the key comes out whether the lock is open or closed, which suits a technician carrying one key across many locks. The ABUS 155/40 avoids the question entirely by opening on a 4-digit code that the property manager can reset between tenants.
16) What padlock takes an interchangeable core so a facility can rekey without buying new locks?
The Sargent 60-858-2 is a removable core padlock in the 758/858 Series with a 2 inch stainless steel shackle, so the core is pulled and replaced when access changes rather than the whole lock. The Medeco 521 G8R is supplied less pop-out cylinder, which lets the cylinder be added to match an existing system. The ABUS 155/40 handles the same problem without cores: its 4-digit code is individually resettable, so access is changed at the lock itself.
17) Is the ABUS 155/40 a commercial-grade padlock or a consumer one?
ABUS classes the 155/40 for commercial use, and it turns up in facilities on lockers, filing cabinets, cash boxes, and supply cabinets. What that does not mean is high-security: the stated protection level is casual theft on medium-value contents. Treat it as an access-control convenience for low-risk interior applications, and step up to a keyed high-security padlock where loss would actually hurt.
