GRANIT™ padlock with stainless steel body and shackle, made in Germany - ideal for outdoor applications

  • Lock body and shackle made of stainless steel
  • Double ball locking mechanism for extreme pulling resistance
  • Available with security card for protection against unauthorized key duplication

FOR THE HIGHEST SECURITY REQUIREMENTS & EXTREME CORROSION PROTECTION

Granite padlock ABUS 37ST/55 - the padlock for demanding outdoor applications.

The 37ST/55 Granit can be used to securely lock halls, doors, and gates near water as well as boats. The body and shackle of the lock are made of stainless steel, which means that it will never rust, even in harsh weather conditions. The ABUS-Plus disc cylinder also ensures a very high level of protection against tampering attempts. Production is carried out according to the European standard CEN class 4. The Granit product series is manufactured in Germany. The key with LED is especially convenient for using in the dark. Granit locks are available with either a code card for quick and easy duplication of spare keys or with a security card for full control over the number of keys in circulation.

Technology:

  • ABUS-Plus disc cylinder: highest protection against manipulation
  • Massive lock body and shackle made of stainless steel
  • Inner components made of non-corrosive materials
  • SZP: comes with security card to protect against unauthorized key duplicates
  • 2 keys, 1 with LED light

Operation and use:

  • To secure valuables/goods of greater value or at a high risk of theft
  • Ideal for use in severe weather conditions (e.g. in coastal regions or ports)
  • Certified and approved padlock
  • To secure e.g. warehouses, industrial sites, factory gates, containers and lorries

ABUS 37ST/55-KD – Frequently Asked Questions

1) Will the ABUS 37ST/55 Granit padlock fit through my hasp? What are the shackle opening dimensions?
The 37ST/55 takes a 15/32 inch diameter shackle, with 1-1/16 inch of horizontal clearance and 1-1/32 inch of vertical clearance inside the shackle. Measure the hasp staple or chain link you need to pass through against those two clearances, and make sure the hasp slot is wider than 15/32 inch. The lock body itself is 2-7/16 inches wide, so you also need that much flat room on the hasp plate.
2) Is the ABUS 37ST Granit padlock OK for a marina, dock, or coastal site?
That is what it is built for. Both the body and the shackle of the 37ST/55 are stainless steel, and the internal components are made of non-corrosive materials, so it holds up near salt water and in harsh weather. ABUS calls out boats, gates and doors near water, ports and coastal regions specifically.
3) Do I order the ABUS 37ST/55 keyed alike or keyed different?
Both are offered. Keyed alike means every lock on the order opens with the same key, which is what you want when one person has to get into a run of gates, containers or compounds without carrying a ring. Keyed different gives each padlock its own key, for separate tenants, separate crews, or anywhere you do not want one lost key to open everything. Pick it at the time of order; it is not something you change later on a disc cylinder.
4) I need a padlock that takes my existing interchangeable core keying. Is the ABUS Granit the right choice?
No. The 37ST/55 uses the ABUS-Plus disc cylinder and comes keyed from ABUS, so it will not accept an SFIC or large format core from your facility keyway. If you standardize on removable cores, look at the Sargent 60-858-2 removable core padlock instead, which has a 2 inch stainless steel shackle. If you want a cylinder-based option in a weather-exposed spot, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body supplied less the pop-out cylinder so you can fit your own.
5) What is the closest stainless steel padlock alternative to the ABUS 37ST/55 Granit for a marine or coastal opening?
The ABUS 37ST/55 Granit uses a stainless steel body and shackle with a 15/32 inch shackle diameter and a 2-7/16 inch body width, built for outdoor and coastal use. The nearest stainless equivalent is the Medeco 521 G8R weather-tight padlock, which uses a solid stainless steel body and is supplied less the pop-out cylinder, so you specify the cylinder separately. Choose the 37ST/55 if you want a complete padlock with keys included; choose the G8R 521 if the cylinder has to match an existing Medeco key system.
6) Can the ABUS 37ST/55 give me audit trail or access records on a remote gate?
No. The 37ST/55 Granit is a mechanical padlock with an ABUS-Plus disc cylinder and a double ball locking mechanism, keyed by conventional keys with a security card controlling duplication. If you need electronic credentialing on an outdoor opening, the Medeco 54515G XT is an electronic indoor/outdoor padlock with a 5/16 inch shackle diameter, non-key retaining, supplied with cylinder. The 37ST/55 remains the choice where no electronics or programming are wanted in the field.
7) How many keys come with the ABUS 37ST/55 Granit padlock, and can copies be made?
Two keys ship with the lock, one of them with an LED light for working in the dark. Key control is handled by a card: the SZP version comes with a security card so that duplicates can only be cut with that card in hand, which keeps the number of keys in circulation under your control. Granit locks are also offered with a code card instead, which makes spare keys easy to order but does not restrict duplication the same way.
8) What makes the Granit 37ST different from a standard brass padlock for high-theft sites?
Two things do the work here. The body and shackle are solid stainless steel rather than brass, and the shackle is held by a double ball locking mechanism, which is what resists a pulling or prying attack on the shackle legs. The cylinder is an ABUS-Plus disc type rather than a pin tumbler, aimed at manipulation attempts. It is rated commercial and intended for warehouses, industrial sites, factory gates, containers and lorries.
9) What security class is the ABUS 37ST/55 made to?
Production of the 37ST/55 follows the European standard CEN class 4. The Granit line is manufactured in Germany.
10) What other stainless or outdoor-rated padlocks could I use instead of the ABUS 37ST/55?
Within the same duty range, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, and the Sargent 858 is a non-key-retaining padlock with a stainless steel shackle in a US4 satin brass finish. The Medeco 54515G XT is an electronic indoor/outdoor padlock if you want an audit trail and programmable access rather than a mechanical key. The main difference with the ABUS is the all-stainless body and shackle combined with a disc cylinder, versus the brass-bodied designs.
11) Is a 15/32 inch shackle too thick for a standard hasp or chain?
At 15/32 inch, the 37ST/55 shackle is heavier than the 5/16 inch shackles on lighter padlocks such as the Schlage KS23D/KS23F brass padlock or the Medeco 54515G XT, and heavier than the 7/16 inch on the Medeco 5260. That thickness is the point on a high-security lock, but it means the hasp slot and any chain link have to accept nearly half an inch of stock. Check the hasp before ordering a batch; a light residential hasp will not take it.
12) What is a lighter-duty alternative to the ABUS 37ST/55 Granit for interior cabinets and low-risk gates?
The 37ST/55 Granit is a heavy stainless padlock with a 15/32 inch shackle and a 2-7/16 inch body, aimed at warehouses, containers and factory gates. Where the risk is lower and the shackle just has to pass a small hasp, the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, and the Medeco 5260 is a brass body padlock with a 7/16 inch shackle in satin chrome using M3 key technology. Both are brass-bodied rather than stainless, so keep the 37ST/55 where salt air or weather exposure is the driver.
13) Does the ABUS 37ST/55 hold the key captive while unlocked, and what if I need the opposite?
The ABUS 37ST/55 Granit is supplied with two keys and a security card and is offered keyed alike or keyed different. If key retention is the deciding factor, the Sargent 758 is a key retaining padlock in a US4 satin brass finish, so the key cannot be withdrawn while the lock is open - useful where a padlock must never be left unlocked and unattended. The Sargent 858 is the non-key-retaining version with a stainless steel shackle in the same US4 satin brass.
14) Will the ABUS 37ST/55 shackle fit a hasp sized for a Sargent 82-856?
Check the clearance, not just the shackle. The ABUS 37ST/55 Granit has a 15/32 inch shackle diameter with 1-1/16 inch horizontal shackle clearance and 1-1/32 inch vertical clearance, on a 2-7/16 inch wide body. The Sargent 82-856 is a non-key-retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle, so its body footprint is smaller than the 37ST/55. Confirm your hasp eye accepts a 15/32 inch shackle before swapping in the ABUS.
15) Does the key stay in the ABUS 37ST/55 while the padlock is open?
On key retention, compare against the peer designs rather than assuming: the Sargent 758 is key retaining, meaning the key cannot be withdrawn while the lock is open, and the Sargent 858 and 82-856 are non-key-retaining. Key retaining is what you want when crews leave locks hanging open and lose keys; non-retaining suits a single keyholder moving between many locks.
