ABUS 180IB/50 C — Resettable 4-Digit Combination Padlock, Solid Brass Body & Stainless Shackle

The ABUS 180IB/50 C is a marine-grade combination padlock built for outdoor and coastal environments where corrosion resistance is non-negotiable. The body is forged solid brass; the shackle is high-quality stainless steel. A precision 4-digit resettable combination eliminates key management entirely — set your own code and change it whenever access needs change. Rated ABUS Security Level 5, it's suited for securing items of medium-to-high value at moderate-to-elevated theft risk: boats, dock equipment, gates, lockers, tool boxes, sheds, switch boxes, and cellar windows.

  • Body: solid forged brass — corrosion-resistant in salt air and wet environments
  • Shackle: stainless steel, 5/16" diameter
  • Combination: 4-digit, individually resettable code (10,000 possible combinations)
  • Internal components: non-corrosive materials throughout
  • Precision locking mechanism with additional tamper protection
  • Security Level: 5 (ABUS scale)
  • Body width: 2-3/64" | Horizontal shackle clearance: 63/64" | Vertical shackle clearance: 1-1/32"

Typical Applications

  • Marine and port environments: boats, dock boxes, vessel hatches, marina gates
  • Outdoor facilities: sheds, storage units, tool boxes, equipment cages
  • Property management: gates, lockers, cellar windows, switch boxes, cupboards
  • Any application requiring keyless access control in severe weather or coastal conditions

ABUS 180IB/50 C – Frequently Asked Questions

1) Will the ABUS 180IB/50 C padlock fit through my hasp or chain link?
Shackle clearance on the 180IB/50 C is 63/64 inch horizontally and 1-1/32 inch vertically, with a 5/16 inch diameter stainless shackle. That means the opening in your hasp, staple, or chain link has to accept a 5/16 inch shackle, and whatever you are locking through has to sit inside roughly a one inch by one inch window. Body width is 2-3/64 inches, so allow that much clearance for the lock body against the door, gate post, or dock box lid.
2) Is a brass padlock actually going to survive salt air at a marina?
That is what the 180IB/50 C is built for. The body is forged solid brass, the shackle is stainless steel, and ABUS specifies non-corrosive materials for the internal components as well, which is the part that usually kills a padlock outdoors long before the body goes. Plated steel padlocks seize up in coastal air because the internals rust even when the shell still looks fine. On docks, marina gates, vessel hatches, and dock boxes this is the right material combination.
3) Should I use a combination padlock or a keyed padlock for gates and shared equipment?
Combination is the right call when more than one person needs access and you do not want to cut, issue, and chase keys. The 180IB/50 C uses a 4-digit code you set yourself, 10,000 possible combinations, and you can change it whenever a tenant, crew, or contractor turns over. Go keyed instead when the lock has to be part of a keying system your facility already runs, when access has to be revocable per person rather than per code, or when a code shared across a crew will inevitably leak. For those cases ZenSupply carries keyed brass-body padlocks like the Schlage KS23D/KS23F and the Sargent 758.
4) I need padlocks that work with my building's key system. Is this one of them?
No. The 180IB/50 C is a combination lock with no cylinder, so it cannot be keyed into a master system or carry an interchangeable core. If you are standardizing a facility on one keyway, look at cylinder padlocks instead: the Sargent 60-858-2 takes a removable core, and the Sargent 82-856 is a non-key-retaining brass-case padlock with a stainless shackle. Use the combination lock where you specifically want to keep an opening off the key system, like a shared gate or a seasonal dock box.
5) What is the closest keyed alternative to the ABUS 180IB/50 C if a facility needs padlocks on a master key system instead of a combination?
The ABUS 180IB/50 C uses a 4-digit resettable combination, so it sits outside any key system by design. When the same brass-body outdoor padlock has to key into a facility's existing system, the Schlage KS23D/KS23F brass padlock takes a 5/16 inch diameter shackle, the same shackle diameter as the 180IB/50 C, and the Sargent 758 is a key retaining padlock in a US4 satin brass finish. For sites standardized on interchangeable core, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, so cores can be rotated without pulling the lock off the hasp.
6) Which padlock has more shackle to work with than the ABUS 180IB/50 C for a thick hasp or a chain through a marina gate?
The ABUS 180IB/50 C gives 63/64 inch of horizontal shackle clearance and 1-1/32 inch of vertical clearance on a 5/16 inch shackle, which fits a standard hasp but not a heavy chain link. The Sargent 60-858-2 carries a 2 inch stainless steel shackle, and the Sargent 82-856 pairs a stainless steel shackle with a 2 inch by 2 inch brass case. Both are keyed rather than combination locks, so the tradeoff for the longer shackle is going back to key management.
7) We want an audit trail on who opened a padlock. Does the ABUS 180IB/50 C do that, and what does instead?
The ABUS 180IB/50 C secures with a mechanical 4-digit resettable code offering 10,000 combinations, which means access is shared by whoever knows the code and there is no record of individual openings. The Medeco 54515G XT is an electronic indoor/outdoor padlock with a cylinder, non-key retaining, on a 5/16 inch shackle diameter, matching the 180IB/50 C shackle diameter so it fits the same hasps. That is the path for a facility that needs credentialed access rather than a shared code.
8) Is the Medeco 5260 a drop-in replacement for the ABUS 180IB/50 C on the same hasp?
Not on shackle fit. The ABUS 180IB/50 C runs a 5/16 inch diameter shackle through a body 2-3/64 inch wide, while the Medeco 5260 in the 52 Series uses a 7/16 inch diameter shackle. A hasp or staple drilled for 5/16 inch will not accept the 5260 shackle without enlarging the opening. If the hasp is fixed, the Schlage KS23D/KS23F brass padlock at 5/16 inch shackle diameter drops through the same hole.
9) Can I set my own combination on the ABUS 180IB/50 C, or is the code fixed?
You set it. The 4-digit combination is individually resettable, so you pick the opening code out of the box and change it later as access needs change. There are 10,000 possible combinations. Practically, that means one lock can follow a unit or a gate through turnovers instead of getting replaced or rekeyed each time.
10) Is the ABUS 180IB/50 C secure enough for a jobsite tool box or equipment cage?
ABUS rates it Security Level 5 on their own scale, which they position for items of medium-to-high value at moderate-to-elevated theft risk: boats, dock equipment, gates, lockers, tool boxes, sheds, switch boxes, and cellar windows. The shackle is 5/16 inch stainless. For a high-exposure jobsite gate or a container left unattended overnight, step up to a heavier shackle: the Medeco 5260 brass-body padlock runs a 7/16 inch shackle.
11) What is the difference between the ABUS 180IB/50 C and the other brass padlocks ZenSupply carries?
The dividing line is how it opens. The 180IB/50 C is a keyless 4-digit combination lock in a forged brass body with a 5/16 inch stainless shackle. The Schlage KS23D/KS23F is a brass padlock with the same 5/16 inch shackle diameter but a keyed cylinder. The Sargent 858 is a non-key-retaining keyed padlock with a stainless shackle in US4 satin brass, and the Sargent 758 is the key-retaining version, meaning the key will not come out while the lock is open. Key retaining is what you want when people habitually walk off with the key still in hand.
12) Can I standardize a whole property on the ABUS 180IB/50 C so every lock opens the same way?
Yes, and that is the practical argument for a resettable combination lock across a fleet of openings. Set every unit to the same 4-digit code and your maintenance crew carries nothing; change the code on all of them when staff turns over. Body width is 2-3/64 inches and the shackle opening is 63/64 by 1-1/32 inches, so confirm your existing hasps across the property accept that footprint before ordering in quantity. Mixed-age hasps on gates, lockers, and cellar windows are where the surprises show up.
13) For a coastal or dock installation, what other padlock bodies resist salt air the way the brass ABUS 180IB/50 C does?
The ABUS 180IB/50 C uses a solid forged brass body with a stainless steel shackle and non-corrosive internal components, which is the standard combination for salt air. Among keyed equivalents, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, the Sargent 858 is a non-key retaining padlock with a stainless steel shackle in US4 satin brass, and the Medeco 5260 in the 52 Series has a brass body in satin chrome. All of these keep dissimilar-metal corrosion out of the shackle-to-body joint the same way.
14) Can I use the same padlock on a gate where the lock must stay open on the hasp while the gate is in use?
The ABUS 180IB/50 C is a combination lock, so the shackle stays with the body whether the code is set or scrambled and there is nothing to retain or drop. If the concern is a key being left in a lock that is hanging open, the Sargent 858 and the Sargent 82-856 are both non-key retaining, meaning the key comes out with the lock open, while the Sargent 758 is key retaining and holds the key until the shackle is closed. Choose based on whether crews should be able to walk away with the key in hand.
15) What padlock should a locksmith specify if the customer is standardizing on a high-security key system across a whole site?
The ABUS 180IB/50 C takes no cylinder at all, since access is set by a 4-digit resettable combination, so it cannot join a site key system. For a site standardizing on a restricted system, the Medeco 5260 uses M3 key technology in the 52 Series, the Sargent 82-856 is a KESO Series padlock with a brass case and stainless shackle, and the Sargent 60-858-2 accepts a removable core so it can be brought onto the site's existing core platform. The 180IB/50 C fits best where a few users share one opening and rekeying should not require a locksmith visit.
16) Is the ABUS 180IB/50 C rated for commercial use or is it a consumer padlock?
It is specified for commercial applications, not homeowner duty. The build backs that up: forged brass body, stainless shackle, non-corrosive internals, and ABUS Security Level 5. Typical placements are marina gates, dock boxes, equipment cages, storage sheds, lockers, and switch boxes.
