We feel the ABUS laminated or 'Eterna' locks are the best all round padlocks which give the perfect compromise of quality, security and price. Now we are the only company to offer these in a master key option!

About this product

Important notes:

  • Each padlock comes with 2 keys but you do need to order your individual "master keys" separately

Do I need a Master Key lock?

Sometimes people get confused between keyed alike and masterkey. A set of master key locks all have their own individual keys (2 per lock) and then there is a single masterkey that can open all the locks within that set.

A set of keyed alike locks however all use the same key. Every lock is identcial. You can find keyed alike locks by clicking here.

The laminated lock has been around for a while but the ABUS Eterna is the next generation and can't be compared to standard laminated locks by other brands. They are made using plates of special hardened steel and a hardened shackle. Everyone in the industry knows that the steel from ABUS is superior in quality than many counterparts which is why this Eterna lock proves so strong for its size.

However, steel can rust which is why ABUS came up with the Eterna finish. It is a special coat that is twice as effective as chrome plating which almost makes these locks as resilient as stainless steel but much stronger.

So happy are we with this lock that we have confidently supplied it to the UK National Grid for their sub stations and also National Rail.

Corrosion Testing:

Padlock Weatherpoof TestingWe regard the new ABUS Eterna as one of the best locks we have. In 2010 ABUS developed a new Eterna treatment process which have given their laminated locks a 40 year lifespan in accelerated weather testing.

The image here shows the locks being subjected to a saline humidity atmosphere which will corrode all but the most weatherproof of padlocks.

Rusty PadlockThe other important factor is that each and every steel plate of the padlock is individually treated whereas all other brands are manufactured and then treated with a standard galvanising process. This basically gives little or no real protection to the weather and especially salt water. During the tests above the ABUS locks came out almost identical with no corrosion marks. All others  appeared like this image on the right and totally inoperable.

In our advice section we talk about the dilemma of the weatherproof / security issue. This basically means that all weather locks use a softer stainless steel metal and whilst hardened steel is stronger, it can rust. This Eterna laminated lock basically does both with a 100% hardened steel construction and weatherproofing to match.

Should I be concerned about duplicates?
In most circumstances no. Due to the high differ number in all ABUS locks, even if every padlock was duplicated twice, the likelihood of finding the other padlock in a large set it slim. However, in some situations, especially in small sets it is necessary to guarantee every padlock will be unique. In this case please contact us and we can quote for a special order which the locks can be made up from scratch and recorded.

Will I be able to add to my set in the future?
Yes. But since every lock is not recorded we cannot guarantee that the new padlocks will be unique and not duplicate padlocks you already have. Once again, the security risk of duplicates is minimal due to the high number of 'differs' contained within any batch of ABUS locks.

We offer three sizes in this master key range padlock. 30mm, 40mm and 50mm. Your choice of padlock size depends on the application but you can click the image above for specific measurement. Remember to make sure the shackle will fit through your bolt or staple!

Uses & Applications:
Master key sets are used in a number of situations but ideal for securing units for hire when an administrator or site manager may require access at any time. Remember that it is important to keep the master-key safe. If a copy is misplaced it can compromise the whole set and you may consider one of our key garages as added security for your master-keys.

Colour Coding:

These padlocks come with a removable blue band. These can be replaced with different colours that we sell separately here.

These are especially useful if you intent to use the locks as safety lock-off items for machinery or switch gear.
