ABUS 55/45-KA – Frequently Asked Questions

1) Will the ABUS 55/45 padlock fit through my hasp or chain link?
Shackle diameter on the 55/45 is 15/64 inch, with 15/16 inch of clearance both horizontally and vertically inside the shackle opening. So the staple or link has to accept a 15/64 inch pin, and whatever you are locking through can be no more than 15/16 inch across in either direction. That covers most light hasps, locker latches, cabinet catches and gate hardware, but it will not swallow a thick heavy-duty hasp staple or a large chain.
2) What is the difference between keyed alike and keyed different on the ABUS 55/45?
Two keying options are sold on the 55/45. Keyed alike (KA) means every lock in the group opens with the same key, which is what you want when one maintenance tech has to reach twenty cabinets or gates on a route. Keyed different (KD) gives each lock its own key, so one lost key compromises one opening instead of the whole set. Pick KA for fleet access, KD for tenant storage, individual lockers, or anywhere the holders should not be able to open each other's locks.
3) I need a padlock that takes my building's existing key system. Is the ABUS 55/45 the right choice?
No. The 55/45 comes with its own ABUS pin cylinder, keyed alike or keyed different, and it is not built to accept an interchangeable core from a facility masterkey system. If you need the padlock on the same key system as the doors, look at a removable core padlock like the Sargent 60-858-2, which takes a removable core and has a 2 inch stainless shackle. The Medeco 54515G XT is an electronic padlock from the System Series if you want audit and scheduled access instead of mechanical keying.
4) What other brass body padlocks are there if the ABUS 55/45 shackle is too thin?
The 55/45 shackle is 15/64 inch, which is on the light side. For a thicker shackle in a brass body, the Medeco 5260 from the 52 Series has a 7/16 inch shackle in satin chrome and uses M3 key technology, and the Schlage KS23D/KS23F brass padlock carries a 5/16 inch shackle. Sargent's 758 is a key retaining padlock in US4 satin brass, with the 858 as the non key retaining version on a stainless shackle.
5) What is the closest brass-body padlock to the ABUS 55/45 if I need a thicker shackle?
The ABUS 55/45 has a 15/64 inch shackle diameter in a 1-11/16 inch wide solid brass body. If the opening needs a heavier shackle, the Schlage KS23D/KS23F brass padlock uses a 5/16 inch diameter shackle, and the Medeco 5260 brass body padlock steps up further to a 7/16 inch shackle. All three keep the brass body, so the difference the buyer is choosing between is shackle stock and the hasp opening it has to pass through.
6) Which padlock takes an interchangeable core so it can go on an existing master key system?
The ABUS 55/45 uses a fixed precision pin tumbler cylinder with mushroom counter pins and is ordered keyed alike or keyed different. A facility that keys padlocks off the same removable core system as its door hardware should look at the Sargent 60-858-2 removable core padlock, which carries a 2 inch stainless steel shackle. For a high security key system instead, 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.
7) What looks like a substitute for the ABUS 55/45 but is not a like-for-like swap?
The Medeco 54515G is an indoor/outdoor padlock with a 5/16 inch shackle diameter supplied with a cylinder, but it is an electronic XT padlock on the System Series, so it belongs to a credential-based access system rather than a straight mechanical key. The ABUS 55/45 is a keyed mechanical padlock with a precision pin tumbler cylinder. Sizing alone will not tell the two apart on a spec sheet, so confirm which system the site is running before treating one as a replacement for the other.
8) Is the ABUS 55/45 padlock OK to leave outside on a gate or shed?
Brass body, hardened steel shackle, and the internal parts are made from non-corrosive materials, so the 55/45 is built to sit outdoors on gates, sheds, basement windows and switchgear without seizing up the way a plated steel lock does. Brass will patina, that is cosmetic. ABUS positions the 55 as basic protection, so it suits deterrence and access control rather than a high-attack exposed opening.
9) Does the ABUS 55/45 lock without the key, or do I have to turn it shut?
It is self locking. Push the shackle down and it latches, no key needed to close it. That matters on a route where someone is securing forty cabinets or lockers in a shift, and it also means the lock can be left in the open position hanging on the hasp and snapped shut later by someone without a key.
10) What kind of cylinder is in the ABUS 55/45, and can it be picked easily?
Inside is a precision pin tumbler cylinder with mushroom counter pins. Mushroom pins are an anti-pick driver shape, so they resist basic raking and casual manipulation better than a plain pin stack. This is not a high security cylinder with a restricted keyway, and ABUS rates the 55 line as basic protection. For a facility that needs key control and patented key blanks, look at a padlock built around a high security cylinder instead.
11) Should I use a key retaining or non key retaining padlock on lockers and cabinets?
Key retaining means the key will not come out while the lock is open, so a user cannot walk off with the key and leave the padlock hanging unlocked. Non key retaining lets the key be pulled at any position. The ABUS 55/45 is self locking on the shackle, so it can be pushed shut with no key present, which is the behavior you want on shared lockers. If you specifically need key retention, the Sargent 758 is a key retaining padlock; the Sargent 858 and Sargent 82-856 are the non key retaining versions.
12) What is the difference between the Sargent 758 and 858 when replacing an ABUS 55/45?
Both are direct mechanical padlock alternatives to the ABUS 55/45. The Sargent 758 is a key retaining standard padlock with a US4 satin brass finish, so the key cannot be withdrawn while the shackle is open. The Sargent 858 is non-key retaining with a stainless steel shackle and the same US4 satin brass finish, which matches the way the ABUS 55/45 behaves, since it closes by pushing the shackle down without the key. Choose 758 where a lost padlock is worse than a lost key, and 858 where crews carry one key across many locks.
13) Is the ABUS 55/45 the right padlock for an exposed outdoor gate, or is there something built for weather?
The ABUS 55/45 has a solid brass body, a hardened steel shackle and internal components made of non-corrosive materials, and is described as protected from wind and weather for use on gates, sheds, switchgear and barriers. Where an opening calls for a purpose-built weather design, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder. That one is a stainless body rather than brass, so it is a different material decision, not simply a heavier version of the same lock.
14) I need a padlock that clears a thick hasp - how does the ABUS 55/45 shackle opening compare?
The ABUS 55/45 gives 15/16 inch of horizontal shackle clearance and 15/16 inch of vertical shackle clearance, which suits standard hasps, cabinets, lockers and toolboxes. For a taller reach over a heavier staple or through a chain, the Sargent 60-858-2 carries a 2 inch stainless steel shackle. Measure the hasp stock and the gap it has to span before choosing between them.
15) If I want to keep a brass finish across a run of padlocks, what matches the ABUS 55/45?
The ABUS 55/45 is a solid brass padlock rated for commercial use. Staying in brass across a property, the Sargent 758 and Sargent 858 both carry a US4 satin brass finish, the Sargent 82-856 uses a 2 inch by 2 inch brass case, and the Medeco 5260 is a brass body padlock finished in satin chrome. The Sargent pair differ from each other on key retention, and the Medeco 5260 puts a chrome finish over the brass body, so confirm the appearance you want as well as the material.
16) Is the ABUS 55/45 rated for commercial use or is it a residential lock?
The 55/45 is a commercial grade item, with a brass body, hardened steel shackle and non-corrosive internals. ABUS describes the 55 as basic protection, meaning it is intended for securing cabinets, lockers, toolboxes, gates, switchgear and barriers rather than for a high-attack exterior opening. For MRO and property fleets it works well as a standard cabinet and gate lock, keyed alike across the route.
17) Can the ABUS 55/45 be used on a marine dock or a wash-down area?
Brass body with non-corrosive internal components handles damp and salt-air exposure better than a plated steel padlock, so the 55/45 holds up on docks, exterior gates and wash-down areas. The shackle is hardened steel, so it will show surface rust in constant spray. Where the environment is genuinely severe, a solid stainless body is the better material: the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder.
