ABUS 41/40HB50 Laminated Steel Padlock with Key, 9/32" Shackle diameter

Check the shackle, not the body. The 41/40HB50 uses a 9/32 inch diameter shackle with 45/64 inch of horizontal clearance between the shackle legs, so anything you lock through has to accept a 9/32 inch bar and leave under 45/64 inch of usable width inside the staple. Vertical clearance under the shackle is 1-31/32 inches, which is what decides whether it clears a thick hasp plate or a chain link stack. Lock body width is 1-47/64 inches.

Yes. The ABUS 41/40HB50 is offered keyed alike, keyed different, and master keyed, in each of six colors: black, blue, green, purple, red, and yellow. Keyed alike gives every lock in the order the same key, which is the usual choice for a maintenance crew working one building. Master keyed keeps each lock on its own key while a master opens all of them, which suits a property manager who wants contractors limited to their own area.

The 41/40HB50 is built for medium value goods at average theft risk, and it is made for weather exposure: laminated steel with ETERNA coating on each laminate, and every laminate individually treated for corrosion protection. The shackle is hardened and double bolted. For a high value target or a site with a real forced entry history, step up to a solid body lock like the Medeco 521 G8R weather tight padlock with a solid stainless steel body.

No. The 41/40HB50 is a fixed pin tumbler padlock, not an interchangeable core lock, so it cannot be pinned into a Best or Sargent SFIC system already running in a facility. If you need padlocks on the same core system as your door hardware, look at a removable core lock such as the Sargent 60-858-2 with a 2 inch stainless steel shackle. The ABUS keys as its own group, which is why the keyed alike and master keyed options are specified at order time.

The 41/40HB50 uses a laminated steel body with ETERNA coating on each laminate and a 9/32 inch hardened shackle. If a solid brass case is preferred over laminates, the Sargent 758 is a key retaining padlock in a US4 satin brass finish, and the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle. Brass bodies are one piece rather than riveted plates, and the Schlage shackle at 5/16 inch is a heavier gauge than the ABUS 9/32 inch, so hasp openings should be checked before swapping.

The 41/40HB50 uses a precision pin tumbler cylinder built into the lock body, so it is not a small format core housing. For a facility keying program built on removable cores, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle in the 758/858 series. That lets a locksmith pull and rekey the core in place rather than replacing the padlock. The ABUS is still the choice where you want padlocks keyed alike, keyed different, or master keyed from the factory in six body colors.

They are not equivalent. The 41/40HB50 is a mechanical padlock with a pin tumbler cylinder that self locks when the shackle is pushed down, and no key is needed to lock it. The Medeco 54515G is an XT electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and a cylinder. Electronic padlocks operate on a programmed credential and an audit trail rather than a cut key, so choosing the 54515G means adopting that access system, not just changing padlock brands.

The 41/40HB50 has a 9/32 inch shackle diameter with 45/64 inch horizontal clearance and 1-31/32 inch vertical clearance, on a body 1-47/64 inch wide. That is the slimmest shackle in the group. The Medeco 54515G and the Schlage KS23D/KS23F both use a 5/16 inch shackle, and the Medeco 5260 steps up to 7/16 inch, so a hasp eye sized for 9/32 inch will not take the 5260 and may not take the 5/16 inch locks. Measure the hasp eye before substituting upward.

Color is how a crew sorts a fleet of locks without reading a tag. The 41/40HB50 comes in black, blue, green, purple, red, and yellow, and each color is available keyed alike, keyed different, or master keyed. Facilities teams typically assign a color per trade, per building, or per keying group, so a tech can see at a glance which key ring the lock belongs to. It is the same lock body in every case.

It is self locking. Push the shackle down and it locks, no key needed to close it, so a crew locking up a run of gates or lockers is not fumbling a key at each one. The key is only needed to open. Inside is a precision pin tumbler cylinder.

Two different constructions. The ABUS is laminated steel, meaning stacked steel plates riveted together, with ETERNA corrosion coating on each laminate and a 9/32 inch hardened shackle. The Schlage KS23D/KS23F is a brass body padlock with a 5/16 inch shackle, and the Medeco 5260 is a brass body lock with a 7/16 inch shackle. Brass bodies resist corrosion by material rather than coating and are common where a facility already standardizes on that keyway; laminated steel takes impact better for the money.

The 41/40HB50 addresses corrosion by treating each laminate individually and applying ETERNA coating to every plate. Where a monolithic corrosion resistant body is wanted instead, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder. The Sargent 858 pairs a stainless steel shackle with a US4 satin brass body and is non-key retaining. A solid stainless body has no rivets or plate seams at all, which is the main structural difference from a laminated build.

The 41/40HB50 is self-locking, meaning it latches by pushing the shackle down without the key in the cylinder. Where a padlock must be key retaining so the key cannot leave with the lock hanging open on a lockout or gate, the Sargent 758 is a key retaining standard padlock. Where non-key retaining is specifically required, the Sargent 858 and the Sargent 82-856, which has a 2 inch by 2 inch brass case with a stainless steel shackle, are both non-key retaining.

The 41/40HB50 is the option built for that: it comes in black, blue, green, purple, red and yellow, each available keyed alike, keyed different or master keyed. The comparable brass and stainless padlocks are specified by finish rather than by color code, for example the Sargent 758 in US4 satin brass and the Medeco 5260, a 52 series brass body padlock with a 7/16 inch shackle diameter and M3 key technology in satin chrome. If crews need to identify a lock across a yard at a glance, the colored laminated body does that without adding tags.

The 41/40HB50 uses a precision pin tumbler cylinder and is offered keyed alike, keyed different or master keyed. Where the key system itself has to be restricted and patent controlled, the Medeco 5260 is a 52 series brass body padlock with M3 key technology, and the Sargent 82-856 is built on the KESO series. Those tie the padlock into a specific manufacturer key system, so the choice depends on which keyway the rest of the facility already runs.

It is classified commercial, made in Germany, and sold through the door hardware line rather than as a retail lock. The construction reflects that: rivets concentrated in the outer laminates so the rivet heads cannot be chipped off, laminates individually treated against corrosion, and a hardened double bolted shackle. It is scoped to medium value property at average theft risk, not to high security applications.

Yes, the 41/40HB50 ships keyed, and the keying arrangement is chosen when you order: keyed alike, keyed different, or master keyed. Keyed different means every lock in the order carries its own unique key, which is what you want when individual tenants or vendors each hold one lock.

They share the 858 platform but are ordered differently. The Sargent 858 is a non-key retaining padlock with a stainless steel shackle in US4 satin brass, in the 858 series. The Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, catalogued in the 758/858 series, so it takes a core rather than a fixed cylinder and carries the longer 2 inch shackle. Against either, the ABUS 41/40HB50 is a laminated steel body with a 9/32 inch shackle and factory keying options in six colors.
