ABUS 28/70 Diskus Stainless Steel Padlock with Key, KA , 25/64" Shackle diam., 2 3/4" Width

Yes. The 28/70 is a keyed padlock ordered by keyway, and there are 21 keyways to pick from: 10, 21, 25, 26, 27, 28, 30, 40, 50, 60, 70, 80, 110, 130, 140, 150, 273, 288, 293, 298 and 303. Order every lock on the same keyway number and they run keyed alike on one key. For a property manager putting locks on storage cages, gates and rooftop hatches across a portfolio, pick one keyway and record it, then every re-order years from now still matches. If you need a second building to be on a separate key, buy that building on a different keyway number.

No. The 28/70 uses ABUS's own precision pin cylinder with anti-pick pins and its own keyways, so it will not accept a Medeco, Sargent or Schlage cylinder and cannot be keyed into those systems. If the requirement is that padlocks run on the master key system already in the building, buy a padlock from that manufacturer instead: the Sargent 60-858-2 removable core padlock takes the core from your existing Sargent system, the Medeco 5260 is a 52 Series brass body lock on M3 key technology, and the Schlage KS23D/KS23F is a brass padlock in Schlage's 20 Series. Buy the ABUS when you want a standalone keyed-alike set that does not have to match anything.

The Medeco 521 G8R weather-tight padlock is the peer with a solid stainless steel body, and it is supplied less pop-out cylinder, so the cylinder is specified separately. The ABUS 28/70 Diskus is a stainless steel padlock supplied keyed, 2-3/4 inch wide with a 25/64 inch hardened steel shackle and a precision pin cylinder with anti-pick pins. The practical difference for an exterior gate or yard application is form: the Diskus round body encloses the shackle for 360 degree protection, while the 521 G8R is a conventional shackle padlock built around a cylinder you choose.

For a removable core program the Sargent 60-858-2 removable core padlock with a 2 inch stainless steel shackle is the peer built for it, since the core comes out and rekeys with the rest of the facility. The ABUS 28/70 Diskus is a keyed padlock with a precision pin cylinder and anti-pick pins, ordered by keyway number, so it keys within its own ABUS system rather than accepting a facility core.

Two peers run a thinner shackle: the Schlage KS23D/KS23F brass padlock and the Medeco 54515G electronic indoor/outdoor padlock both list a 5/16 inch shackle diameter, and the Medeco 5260 brass body padlock runs heavier at 7/16 inch. The ABUS 28/70 Diskus sits between them at 25/64 inch, with 49/64 inch horizontal shackle clearance and 11/16 inch vertical clearance - measure the hasp eye and the gap behind it against those two numbers before committing, because the Diskus round body also needs room to sit flat against the hasp.

The Sargent 60-858-2 removable core padlock carries a 2 inch stainless steel shackle, which is the longer reach in the comparable group for wrapping a chain or clearing a thick hasp. The ABUS 28/70 Diskus gives 49/64 inch horizontal and 11/16 inch vertical shackle clearance in a 2-3/4 inch wide body - that short exposed shackle is the point of the Diskus design, since it leaves almost nothing for bolt cutters to grab, but it will not reach around a chain.

One decision: the keyway. The 28/70 is offered on keyways 10, 21, 25, 26, 27, 28, 30, 40, 50, 60, 70, 80, 110, 130, 140, 150, 273, 288, 293, 298 and 303. Body size, stainless body, shackle diameter and clearances are fixed on this model, so there is no finish or shackle-height option to sort out. Locks sharing a keyway number operate on the same key, so the keyway is really you deciding which locks on your site key together.

The 28/70 has a stainless steel body with a hardened steel shackle, which is what puts it outdoors on gates, meters, and marine or food-plant applications where a brass or plated body streaks and seizes. ABUS builds it with their Diskus deep-welding construction and makes it in Germany. It is specified as a commercial-duty lock rather than a residential one.

Key retention is not a published feature of the 28/70, so if that is a hard requirement, order a lock that states it. The Sargent 758 is a key retaining standard padlock, meaning the key will not come out while the lock is open. The Sargent 858 and the Sargent 82-856 KESO are both non-key-retaining, and the Medeco 54515G XT electronic padlock is non-key-retaining as well. Key retention matters most on shared-crew jobs and utility gates, where the rule is that the lock is never left hanging open with a key in the cylinder.

For an audited or credential-based opening the Medeco 54515G XT electronic indoor/outdoor padlock is the peer in that class; it is non-key retaining, uses a 5/16 inch shackle, and ships with a cylinder. The ABUS 28/70 Diskus is a mechanical keyed padlock with a precision pin cylinder and anti-pick pins, ordered against an ABUS keyway number - it opens with a key and keeps no record of who opened it. Use the Diskus where mechanical stainless security on an exposed gate is the requirement and the XT where the site needs electronic credentials.

They are not the same material choice. The brass body peers are the Medeco 5260 in the 52 Series with a 7/16 inch shackle and satin chrome finish, the Schlage KS23D/KS23F brass padlock with a 5/16 inch shackle, and the Sargent 82-856 with a 2 inch by 2 inch brass case and a stainless steel shackle. The ABUS 28/70 Diskus is stainless steel throughout the body with a hardened steel shackle and the Diskus deep-welding construction, and it is rated commercial. Where the specification calls out stainless for the body, a brass case padlock does not meet it regardless of how the shackle is made.

Staying in one family means the Sargent padlocks: the 758 Series key retaining 758, the 858 Series non-key retaining 858, the 758/858 Series 60-858-2 removable core, or the 82-856 in the KESO Series. The ABUS 28/70 Diskus is ordered by ABUS keyway number and keyed alike within that ABUS system, so it stands as its own key group rather than joining a Sargent or Medeco system. Many sites run the Diskus on exterior gates and sheds as a deliberately separate key from the building master.

Not the 28/70. It is a mechanical keyed padlock with a pin cylinder, so there is no record of who opened what. For access records, the Medeco 54515G XT is an electronic indoor/outdoor padlock in the System Series, which is the type of product to look at when a utility, government or healthcare site needs to know which credential opened which lock. Choose the ABUS Diskus when the requirement is physical resistance and a simple keyed-alike set, not electronic control.
