ABUS 37RK/55-KD – Frequently Asked Questions

1) Should I order the ABUS 37RK/55 keyed alike or keyed different?
Two keying options are offered on the 37RK/55: KA (keyed alike) and KD (keyed different). Keyed alike is what you want when one person, or one crew, opens a run of gates, containers or warehouse doors and you do not want a ring of keys. Keyed different is the choice when separate tenants, subcontractors or departments each control their own lock and should not open each other's. Every lock ships with two keys, one of them with an LED light in the head, which matters on a yard gate after dark.
2) What does the RK in ABUS 37RK/55 mean? Can it be keyed to my existing ABUS Plus keys?
RK means re-keyable. The cylinder on the 37RK/55 can be re-keyed to match an existing ABUS Plus key, so if you already run ABUS Plus on a site you can bring new locks onto the same key rather than starting a second key system. The cylinder is an ABUS Plus disc cylinder. Note the distinction from SZP versions, which come with a security card instead.
3) What standard is the ABUS Granit 37/55 padlock built to, and will an insurer accept it?
The 37/55 is manufactured to the European standard EN 12320 and ABUS states it meets the special requirements of insurance companies. It is sold as a certified and approved high security padlock, made in Germany. If your policy or your spec names a padlock standard, EN 12320 is the one this lock is built to.
4) Why pick the ABUS 37RK/55 over a standard brass-body padlock for a high-theft site?
Two things separate it. The body and shackle are hardened special steel rather than brass, and the shackle uses a double ball locking mechanism, which is what resists a pull attack on the shackle legs. Brass-body locks like the Sargent 758 Series or the Medeco 5260 in the 52 Series are the right tool for interior doors, cabinets and lower-risk openings, and they are lighter and smaller. If a truck, container or yard gate is the target, the Granit is the class of lock you want.
5) I need padlocks on an interchangeable core system across the facility. Is the ABUS 37RK/55 Granit the right choice?
The ABUS 37RK/55 Granit carries an ABUS Plus disc cylinder, and the RK designation means the cylinder can be re-keyed to match an existing ABUS Plus key. That standardizes it to an ABUS Plus system, not to a removable core system. If the facility is built around removable cores, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle in the 758/858 Series, which lets the padlocks take the same core as the rest of the openings.
6) My hasp only takes a 5/16 inch shackle. What padlock fits instead of the ABUS 37RK/55 Granit?
The ABUS 37RK/55 Granit uses a 7/16 inch shackle, which will not pass through a hasp drilled for 5/16 inch. Two padlocks in that smaller shackle size are the Schlage KS23D/KS23F, a 20 Series brass padlock with a 5/16 inch shackle, and the Medeco 54515G XT, a non-key-retaining indoor/outdoor padlock with a 5/16 inch shackle supplied with cylinder. Measure the hasp eye before ordering, since shackle diameter is the dimension that decides fit.
7) Is the Medeco 54515G XT a substitute for the ABUS 37RK/55 Granit?
They are not the same kind of lock. The ABUS 37RK/55 Granit is a mechanical padlock with an ABUS Plus disc cylinder and two supplied keys, opened by key alone. The Medeco 54515G XT is an electronic indoor/outdoor padlock in the System Series, which means it belongs to an electronic access system rather than a plain key hierarchy, and its shackle is 5/16 inch rather than the 7/16 inch on the ABUS. If you are replacing a mechanical padlock one for one, the XT is a system decision, not a drop-in.
8) Which padlock meets insurance requirements for securing a container or factory gate?
The ABUS 37RK/55 Granit is made to the European standard EN 12320, meets the special requirements of insurance companies and is described as a certified and approved padlock for warehouses, industrial sites, factory gates, containers and lorries. It is also available with a security card, so original keys can only be duplicated by presenting that card at a licensed ABUS dealer, which matters where key control is part of the requirement. Among the comparable padlocks the Sargent 82-856 KESO and the Medeco 5260 with M3 key technology are the other high security key system options.
9) How wide is the ABUS Granit 37RK/55 body, and will it clear a recessed hasp or a container lock box?
Body width on the 37RK/55 is 2-29/64 inches. It is a big lock, so measure your hasp pocket or lock box opening before you commit. On roll-up doors, containers and factory gates, which is what this Granit is built for, the body usually has room; on a shallow recessed hasp it may not seat.
10) Code card or security card on an ABUS Granit 37/55 padlock, which should I get?
The two cards do opposite jobs. A code card carries a number that lets anyone take it to a retailer and have keys cut, which is convenient and is the wrong choice if key control matters. A security card means original keys can only be duplicated by presenting that card at a licensed ABUS dealer, so duplication stays under your control. For a property manager or a facility handing keys to contractors, the security card is the one that keeps a copied key from showing up later.
11) Is the ABUS Granit 37RK/55 rated for outdoor use on gates and containers?
Yes. The body and shackle are hardened alloy steel with a black Granit coating added specifically for corrosion resistance, and ABUS lists it for halls, doors, gates, containers and trucks. It is a commercial-duty lock, not a residential one.
12) Is a 5/16 inch shackle padlock a fair substitute for the ABUS Granit 37RK/55?
Not on the same opening. The Granit 37RK/55 carries a 7/16 inch shackle, and locks such as the Schlage KS23D/KS23F brass padlock or the Medeco 54515G run a 5/16 inch shackle. That is a thinner shackle in a smaller lock, sized for lighter hasps and lower-risk service. It also means a hasp drilled for the ABUS will happily accept the smaller lock, but not the reverse, so if you are standardizing hardware, size the hasp to the largest shackle you plan to use.
13) What do I need besides the ABUS Granit 37/55 to secure a warehouse door or gate properly?
The lock is only as good as what it hangs on. ABUS specifies the high security Hasp No. 130 with the Granit 37/55, and the pairing matters because the hasp has to accept the 7/16 inch shackle and shield the shackle from a bolt cutter or a pry bar. A thin surface hasp on wood screws defeats the point of the lock. The padlock itself arrives with two keys, one LED lit, so no separate key order is needed.
14) Will the ABUS 37RK/55 Granit fit the same hasp as a Sargent 858 padlock?
Check both the shackle diameter and the clearance under the shackle. The ABUS 37RK/55 Granit has a 7/16 inch shackle with 1-5/64 inch horizontal clearance and 1-3/64 inch vertical clearance, and a body 2-29/64 inch wide. The Sargent 60-858-2 is specified with a 2 inch stainless steel shackle, a taller opening than the ABUS gives, so a hasp with deep or stacked staples that suited the Sargent may not close on the ABUS. On a flat hasp the ABUS clearances are usually the deciding numbers.
15) Do I need the ABUS 37RK/55 Granit, or is a standard brass padlock enough for an interior storage cage?
The ABUS 37RK/55 Granit is built for high-value goods at high risk of theft, with a hardened alloy steel body and shackle, double ball locking for pulling resistance and a Granit coating for corrosion protection, and it is made to the European standard EN 12320 for exterior work such as gates, containers and trucks. For an interior cage where the threat is casual rather than attack, a brass body padlock such as the Sargent 758, a key retaining padlock in US4 satin brass, or the Schlage KS23D/KS23F 20 Series brass padlock covers the opening without the hardened steel construction.
16) Which padlocks let the key come out only when the lock is locked, and does the ABUS 37RK/55 Granit do that?
Key retention is a per-model behavior, and among the comparable padlocks the Sargent 758 is key retaining, meaning the key stays captive while the shackle is open, while the Sargent 858 and the Sargent 82-856 KESO are non-key-retaining. Key retention is the feature that keeps a technician from walking off with an open lock hanging on a gate, so confirm it before standardizing a fleet on any one model. The ABUS 37RK/55 Granit ships with two keys, one of which has an LED light.
17) For a coastal or washdown site, how does the ABUS 37RK/55 Granit compare to a stainless steel padlock?
The ABUS 37RK/55 Granit handles corrosion through material and coating: hardened alloy steel body and shackle with a black Granit coating specified for improved corrosion protection. The stainless approach is a different construction. The Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder, and the Sargent 858 pairs a brass case with a stainless steel shackle. All three are aimed at outdoor exposure; the choice comes down to whether you want hardened coated steel or a stainless body.
18) Can I order the ABUS 37RK/55 Granit keyed alike so one key opens every gate, and what are the alternatives?
The ABUS 37RK/55 Granit is a keyed padlock offered both keyed alike, so one key operates every lock in the group, and keyed different, so each lock has its own key. Because it is an RK model the cylinder can also be re-keyed to match an existing ABUS Plus key, which lets you add locks to a key system already in place. If the site key system is Sargent rather than ABUS, the Sargent 60-858-2 removable core padlock takes a core from that system instead.
19) What padlock should I use if the site is standardized on a Sargent high security key system?
The ABUS 37RK/55 Granit runs an ABUS Plus disc cylinder, so it keys into an ABUS Plus system rather than a Sargent one. Where the site is already on Sargent, the Sargent 82-856 is a KESO Series non-key-retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle, which keeps the padlocks on the same key system as the doors. The trade is construction: the ABUS body and shackle are hardened alloy steel with a Granit corrosion coating.
20) The ABUS 37RK/55 Granit comes with its cylinder. Which comparable padlocks need a cylinder ordered separately?
The ABUS 37RK/55 Granit arrives complete with its ABUS Plus disc cylinder and two keys, one with an LED light, so nothing further is needed to put it into service. The Medeco 521 G8R is supplied less pop-out cylinder, meaning the cylinder is a separate line on the order, while the Medeco 54515G XT is listed with cylinder. Confirm which way a padlock is furnished before it ships to a job site, since a bodies-only shipment stops the install.
21) Does the ABUS 37RK/55 hold the key when it is unlocked, or does the key come out?
The key can be withdrawn from the 37RK/55 when the lock is open. If your procedure depends on the key staying captive in the lock so it cannot be pocketed or left with the padlock hanging open, look at a key-retaining model such as the Sargent 758, which is listed as key retaining. Non-key-retaining options in the same family include the Sargent 858 and the 82-856.
