ABUS 55MB/50-KA – Frequently Asked Questions

1) Will the ABUS 55MB/50 padlock shackle fit through my hasp or chain link?
The 55MB/50 gives you 1 inch of horizontal shackle clearance and 5/16 inch of vertical clearance, so the opening the shackle passes through has to accept those numbers. That is enough for most standard hasps, a locker or toolbox staple, or a cable loop, but a heavy chain with thick links or a shrouded hasp with a tight slot will not take it. Measure the slot before you order.
2) Should I order the ABUS 55MB/50 keyed alike or keyed different?
Two keying options are offered: KA keyed alike, where every lock in the order opens on the same key, and KD keyed different, where each lock has its own key. If you are a property manager putting locks on a run of storage rooms, gates, or meter cabinets that the same crew opens, keyed alike is the one that saves the key ring. Keyed different is for tenant-controlled or separately assigned openings where you do not want one key to open everything.
3) Is the ABUS 55MB/50 padlock any good outdoors on a gate or in a damp basement?
Brass body, hardened steel shackle, and internal parts made of non-corrosive materials, which is why ABUS lists gates, cellar windows, sheds, switchgear and barriers as uses. Brass does not rust the way a plated steel body does, so it holds up on an exterior gate or in a damp mechanical room better than a painted laminated lock. ABUS rates the 55 as basic protection, so it is a deterrent lock, not a high-security lock for an exposed high-value opening.
4) Can I key the ABUS 55MB/50 into my building's existing Schlage or Sargent master key system?
No. The 55MB/50 uses its own 5-pin ABUS cylinder and is ordered keyed alike or keyed different within ABUS keying, not built into another manufacturer's system. If the requirement is that the padlock opens on the same key as the rest of the facility, you want a padlock that takes your existing core instead: the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless shackle, and the Medeco 54515G is an indoor/outdoor padlock supplied with a cylinder.
5) What is a stainless steel alternative to the ABUS 55MB/50 brass padlock for coastal or washdown areas?
The Medeco 521 G8R weather-tight padlock has a solid stainless steel body, where the 55MB/50 uses a brass body. Both are corrosion-oriented designs, but the G8R-521 is supplied less its pop-out cylinder, so a cylinder has to be specified separately, while the 55MB/50 is a keyed 5-pin lock complete as shipped.
6) Which brass padlock should I use if my facility is standardized on a Sargent keyway instead of a standalone lock?
The Sargent 758 is a key retaining padlock in a US4 satin brass finish, and the Sargent 82-856 is a non-key retaining padlock with a 2 inch by 2 inch brass case and stainless steel shackle. Both sit inside Sargent keying systems, so they can be brought onto an existing Sargent key. The ABUS 55MB/50 is a brass body padlock with its own 5-pin cylinder and is ordered keyed alike or keyed different.
7) What is the closest brass body padlock to the ABUS 55MB/50 from another manufacturer?
The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, and the Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter and M3 key technology in satin chrome. The ABUS 55MB/50 is a brass body lock with a 5-pin cylinder, 1-7/8 inch body width, 1 inch horizontal shackle clearance and 5/16 inch vertical shackle clearance, so match the shackle opening to the hasp before swapping.
8) My hasp needs a taller shackle than the 55MB/50 gives me - what else works?
The ABUS 55MB/50 has 5/16 inch vertical shackle clearance and 1 inch horizontal shackle clearance, which suits a close-fitting hasp. Where a chain or a thicker staple needs more room, the Sargent 60-858-2 carries a 2 inch stainless steel shackle and the Sargent 858 uses a stainless steel shackle as well.
9) How wide is the ABUS 55MB/50 lock body?
The brass body measures 1-7/8 inches across. That width matters where the lock sits in a recessed hasp or between a gate post and a frame, since a body wider than the pocket will not seat and the shackle will not close square.
10) Does the ABUS 55 brass padlock lock without the key, or do I have to turn the key to secure it?
It is self-locking. Push the shackle down and it latches, no key needed to close it. For a maintenance crew closing out twenty cabinets or lockers on a round, that is the difference between carrying the key in hand and just snapping each one shut.
11) What is a good brass padlock alternative to the ABUS 55MB/50?
Two close ones in brass: the Schlage KS23D/KS23F brass padlock with a 5/16 inch shackle diameter, and the Medeco 5260 from the 52 Series, a brass body padlock with a 7/16 inch shackle and M3 key technology in satin chrome. The Schlage is the nearest straight swap on shackle size. The Medeco steps up the shackle diameter and puts a restricted key system behind it, which matters if you need key control on who can duplicate. Sargent's 758 is a key retaining padlock in US4 satin brass finish, meaning the key will not come out while the lock is open, which some facilities require so keys do not walk off.
12) Is the ABUS 55MB/50 padlock key retaining?
It is not. The 55 is self-locking by pushing the shackle down, so the key comes out with the lock open and the lock can be closed without it. If your facility requires the key to stay captive while the lock is off the hasp, so keys cannot be pocketed or left behind, look at the Sargent 758, which is a key retaining padlock.
13) Is there an electronic padlock I can use instead of a mechanical brass one for audit trail on remote sites?
The Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and cylinder included. It is a credential-based lock rather than a mechanical pin tumbler one; the ABUS 55MB/50 is a mechanical brass padlock with a 5-pin cylinder and no electronics.
14) Do I need a key retaining padlock, and which ones are they?
Key retaining means the key cannot be withdrawn while the lock is open, which keeps keys from being left in a rack of open locks. The Sargent 758 is key retaining; the Sargent 858 is non-key retaining with a stainless steel shackle in US4 satin brass, and the Sargent 82-856 is non-key retaining as well. The ABUS 55MB/50 is self-locking, closing without the key by pushing the shackle down.
15) How many pins are in the ABUS 55MB/50 cylinder?
A 5-pin precision pin tumbler cylinder, with mushroom counter pins that resist picking. Five pins is a conventional pin count for a commercial padlock of this class; it gives you real key differs across a keyed different order without moving to a restricted high-security keyway.
16) Is the ABUS 55MB/50 rated for commercial use or is it a residential padlock?
Classed as commercial. In practice that means it belongs on gates, storage cages, tool cribs, lockers, switchgear cabinets and barriers rather than being a light consumer lock, but ABUS positions the 55 family as basic protection. For a high-exposure opening where the lock is the only thing protecting real value, a stainless body weather-tight design like the Medeco 521 G8R is the heavier option.
