Plastic-Covered Aluminum Core Padlock 74

Strong mixture: Secure your valuables in especially hot environments as well as near electrical equipment with this aluminum lock with synthetic coating.

SAFETY LOCK

The Safety Lock 74 supplements communication between your employees before and during maintenance work and ensures a high level of transparency in the workflow.

The 74 Safety lock helps to protect your employees in several ways - for one, because it follows the golden rule of "one lock - one key - one operator" and thus provides a high level of security. It also has the key-retaining feature that means the key can only be pulled out when the padlock is fully locked. Only a fully closed lock is truly secure. The 74 also makes it easy to organize and plan locking systems. The ten colors of the Safety Lock 74 also virtually eliminates the possibility of mixing up keys or assignments in the team. In addition to the different colors, our high-quality and clearly legible laser engravings can make it clear which person or purpose is assigned to the individual padlock.

Technology:

  • Solid aluminum core with steel shackle for best physical strength
  • Body and shackle insulated against electric shock
  • NANO-PROTECT™ shackle for superior corrosion resistance
  • Intrinsically safe, key retaining
  • Automatic locking for user convenience
  • Compact and lightweight
  • High precision 6-pin cylinder for better tamper resistance

ABUS 74LB/40 KD BLACK – Frequently Asked Questions

1) Is the ABUS 74LB/40 an approved lockout tagout padlock for electrical work?
That is what the 74 was built for. The aluminum core and steel shackle are both insulated with a synthetic coating so the body and shackle are protected against electric shock, and the lock is key retaining, meaning the key cannot come out until the padlock is fully closed. That enforces the one lock, one key, one operator rule an energy control program runs on. It is a 40mm wide body, so it sits on a breaker lockout or a group hasp without adding much bulk.
2) Can I get the ABUS 74LB/40 keyed alike across a crew, and does it come keyed different?
Both. Every one of the ten body colors is offered keyed alike or keyed different, so you can run one key across a maintenance crew's set or issue each tech a unique key for lockout work. Nine colors show as orderable options plus the base body. Keyed different is the correct choice for lockout tagout, where only the person who applied the lock should be able to remove it; keyed alike is for gates, cabinets and fleet applications where one key should open everything.
3) Should I use the ABUS 74 aluminum safety padlock or a brass or steel padlock?
Pick the 74 when the lock has to be light, non conductive and color coded, which is lockout tagout and electrical maintenance. Its aluminum core with insulated coating is a deliberate trade of mass for insulation and weight. For general facility security where nobody is working on energized equipment, a brass body is the usual pick, like the Sargent 758 key retaining padlock or the Schlage KS23D/KS23F brass padlock. If you standardize on interchangeable core so a facility locksmith can swap cylinders, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless shackle.
4) What is the closest alternative to the ABUS 74LB/40 padlock for a lockout program if the lock must not release the key until it is locked?
The ABUS 74LB/40 is key retaining, meaning the key comes out only once the padlock is fully closed, which is the behavior a lockout/tagout program depends on. Among other padlocks, the Sargent 758 is also a key retaining standard padlock, in a US4 satin brass finish. If you want the opposite behavior, so the key can be withdrawn with the shackle open, the Sargent 858 and the Sargent 82-856 are both non key retaining, as is the Medeco 54515G electronic indoor/outdoor padlock. Match that one characteristic first, because it decides whether the lock enforces one lock, one key, one operator.
5) Which padlock should I use instead of an ABUS 74LB/40 on an exposed outdoor gate?
The 74LB/40 is a weather resistant aluminum core lock with a plastic covered body, built for hot environments and work near electrical equipment. For a fully exposed outdoor hasp where corrosion is the main concern, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder so it takes your own cylinder. The Sargent 858 and Sargent 60-858-2 both use a stainless steel shackle, with the 60-858-2 carrying a 2 inch shackle for thicker hasps and chain. Those are metal-bodied locks rather than insulated ones, so they suit a gate rather than an electrical isolation point.
6) I need padlocks that fit our existing key system across a facility. Is the ABUS 74LB/40 the right choice or should I look at a different padlock?
The ABUS 74LB/40 is rekeyable with a 6-pin cylinder and ships keyed alike or keyed different across nine body colors, which suits a program keyed as its own family with color coding by trade or person. If you standardize on a small format interchangeable core so the padlocks rotate on the same core stock as your doors, the Sargent 60-858-2 is a removable core padlock. If your facility runs a proprietary Sargent system, the 82-856 uses the KESO series and the Medeco 5260 is a 52 Series brass body padlock built on M3 key technology, so each of those ties the padlock into that manufacturer's key system rather than a standalone one.
7) What colors does the ABUS 74LB/40 safety padlock come in?
Black, blue, brown, green, orange, purple, red, white and yellow, each available keyed alike or keyed different. On a lockout program the color is not cosmetic, it is how you assign a lock to a trade or a shift so keys and assignments don't get mixed up in the field.
8) Can the ABUS 74LB/40 be rekeyed into an existing padlock key system?
The 74LB/40 is rekeyable and runs a 6-pin cylinder, so a locksmith can repin it rather than you buying new locks when a key walks off. Six pins gives more differs than a 4 or 5 pin padlock cylinder, which matters when you are keying a large facility set.
9) Will an aluminum padlock hold up outdoors on a gate or yard enclosure?
The 74LB/40 is rated weather resistant, and the shackle carries a NANO-PROTECT coating for corrosion resistance while the aluminum body is covered in synthetic plastic. That combination is aimed at wet and hot environments. If you need a solid stainless body instead of coated aluminum for a coastal or washdown site, the Medeco 521 G8R weather-tight padlock has a solid stainless steel body.
10) Do I have to hold the ABUS 74LB/40 key to lock it, or does it snap shut?
It is self locking. Push the shackle closed and it latches without the key, which is what you want when a tech is applying a dozen locks to a group hasp. The key only comes back out once the lock is fully closed, so a half seated shackle keeps your key hostage until you fix it.
11) Will the ABUS 74LB/40 key stay in the lock when it is open?
No, and that is intentional. The 74 is key retaining, so the key stays captive in the cylinder any time the shackle is open and only releases once the padlock is fully locked. If your application needs to pull the key with the lock hanging open, look at a non key retaining padlock instead, such as the Sargent 858 or the Sargent 82-856.
12) Can I swap a Medeco 54515G in place of an ABUS 74LB/40 padlock?
They solve different problems. The ABUS 74LB/40 is a mechanical padlock with a 6-pin cylinder, self locking so it latches when you push the shackle closed, and key retaining. The Medeco 54515G XT is an electronic indoor/outdoor padlock supplied with a cylinder and is non-key retaining, so access is managed by programmed credentials and an audit trail rather than by cut keys and color assignment. If you are buying for a lockout board where each worker carries one key on one lock, the 54515G is not the equivalent part; if you are buying for gates and cabinets where you want to grant and revoke access without recutting keys, it is the one to look at.
13) Is there a simpler brass padlock to use where the ABUS 74LB/40 insulation is not needed?
The 74LB/40 pairs a solid aluminum core with a synthetic coating that insulates the body and shackle against electric shock, which is what you pay for on an electrical isolation point or in a hot environment. On an ordinary storage cabinet, tool crib, or utility gate, a plain metal-body lock covers it: the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch shackle, the Sargent 758 is a key retaining standard padlock in US4 satin brass, and the Medeco 5260 is a 52 Series brass body padlock in satin chrome. None of those are insulated or color-coded, so keep the 74LB/40 where electrical safety or per-person color assignment is the point.
14) Which padlock takes a longer shackle than the ABUS 74LB/40 for a thick hasp or a chain?
The ABUS 74LB/40 gives 38 mm of vertical shackle clearance and 19 mm horizontal on a 40 mm wide body, which is sized for a standard hasp or a lockout hasp stack rather than a chain. The Sargent 60-858-2 carries a 2 inch stainless steel shackle, giving noticeably more vertical reach for thick hasps, doubled hasps, or a chain link, and it is a removable core lock. Confirm the link or hasp thickness against the 38 mm figure before ordering the ABUS for that opening.
15) What padlock do I order if I want to install my own cylinder rather than the one that comes with it?
The ABUS 74LB/40 comes as a complete lock with a high precision 6-pin cylinder and is rekeyable, so a locksmith works with the cylinder that is in it. If your standard is to fit your own cylinder, the Medeco 521 G8R is supplied less pop-out cylinder, meaning the body ships without one and you specify the cylinder separately. The Sargent 60-858-2 takes the other approach with a removable core, so the core swaps in the field on the same core stock as the rest of the system.
16) Between the Sargent 758 and Sargent 858, which one matches the ABUS 74LB/40 behavior?
The 758 is the match on key handling. The Sargent 758 is a key retaining standard padlock in US4 satin brass, the same behavior as the ABUS 74LB/40, where the key stays captive until the lock is closed. The Sargent 858 is non key retaining with a stainless steel shackle, also in US4 satin brass, so the key comes out with the shackle open. Both Sargent locks are brass-cased rather than insulated aluminum, so neither substitutes for the 74LB/40 where the body and shackle need to be insulated against electric shock.
17) Is the ABUS 74LB/40 padlock rated for commercial and industrial use?
It is a commercial grade lock, 40mm body width, built around a solid aluminum core with a steel shackle and a 6-pin cylinder for tamper resistance. Facilities buy it in quantity for maintenance and energy control programs because it can be laser engraved with a name or department to make each lock traceable to a person.
