Protector 16mm High Security Chain Sold Secure Gold in all Categories

Uncroppable, High Security Protector Chain.

Our 16mm range of Protector High Security Chains are manufactured from high-grade European steel, with specialist heat treatment and finishing processes undertaken in the United Kingdom to precise specifications.

This ensures consistency and perfect performance from every single chain, which is one of the reasons that they have achieved RiDE Magazine Best Buy and Recommended awards making this chain a popular choice as a motorbike security chain.

The Protector 16mm chain is guaranteed impossible to bolt crop by hand, which is a great reassurance if you are looking to use it to secure high value items or equipment such as motorcycles, ATVs, caravans, etc.

...but remember, if you are using your chain with other security devices, i.e. in a ground anchor, chain and padlock combination, the whole system is only as good as its weakest link ...and sadly there are many inferior chains on the market!


Quality & Performance

All Protector 16mm chains are approved by the UK Police, and are Secured-by-Design Accredited.

These high grade Protector 16mm, chains really are impossible to bolt-crop by hand.

Thieves frequently use enormous, heavy duty Irwin Record 42" bolt croppers as their tool of choice, but our Protector 16mm chains have proven impossible to crop even with this powerful tool. In fact, if you keep trying to crop one of these chains, it is likely to be the jaws of the bolt croppers that break!

The Protector 16mm chains (and 19mm chains) are the highest-approved chains on the market, having achieved Sold Secure Caravan Gold as well as Motorcycle, ATV, Motor Scooter, Bicycle, Commercial Vehicles & Plant, Car & Van Gold.

This is largely down to the high grade European raw material used for their manufacture and the specialist and precise heat treatment process evolved over several years. You simply can`t buy better!

There are videos on the Internet showing inferior, invariably Far Eastern-produced, chains being cut in seconds with bolt croppers, ...but you won`t see our Protector 16mm or 19mm chains being bolt-cropped, guaranteed!

Of course, a chain as robust as the Protector requires a padlock that will offer a complimentary performance, which is why we recommend the Sold Secure Gold rated Federal PD FD740P or Squire PD SS65CS Close Shackle Padlocks.


Mobile and Bicycle Security

There are different priorities when it comes to mobile security as it is often impractical to carry heavy locks and chains around with you, but remember that over 80% of bike thefts occur from the home, so security at home should generally be your first priority.

There are however situations where the 16mm chains and the locks that go with them are simply too bulky or too heavy, which is why we also supply Protector 11mm long link chains. Although our 11mm chains are not quite as secure as the 16mm chains, they still offer robust protection, are easy to handle and can be used with a lighter-weight padlock.

Bicycle security in particular is generally better handled with the 11mm chain as they will fit more easily through the spokes of bicycle wheels, and the smaller and lighter Federal PD FD730P (close shackle), or Federal PD FD730 padlocks are generally better suited for use with bicycles and various medium-value items.


Chain Lengths and Weights

Normal stock lengths are 1.0m, 1.5m and 2.0m for the Protector 16 and 11mm chains (other lengths are available up to 6.0metres – but if you can`t see what you need, call our friendly team, we`d love to help, t: 01273 475500.

See below for weight per metre for each of our Protector chains and the normal maximum length we can supply:

   Protector 16mm Chain weighs 4.5kg per metre – max length: 6.2m

   Protector 11mm Chain weighs 2.1kg per metre – max length: 6.2m


Please Note; Chains over 3 metres in length are normally only required for securing heavy plant, etc. and so are supplied unsleeved as standard. Should you require sleeved longer chain, please call to discuss your requirements and the extra cost of sleeving.

About Sold Secure testing and ratings

Sold Secure is an independent British security testing and approvals organisation that awards Gold standard to the highest security products, with Silver and Bronze for lower grade products. Motorcycle Gold is a higher rating than Bicycle Gold; Caravan Gold is a higher rating than Motorcycle Gold.

Sold Secure Chain Ratings: The Sold Secure test regime has been updated to take account of the higher ratings achieved by the 16mm chains so many previously Motorcycle Gold-rated products have not achieved that level when re-tested. Be wary of chains that were granted Motorcycle Gold status prior to 2008 - a recent re-test is the only way to be confident of the grading relative to the current standard.

We strongly recommend that you use the best chain that is practical and affordable for your needs, bearing in mind the type of attack that is common for the items that you are protecting. Where bolt-cropping is a common form of attack for a given application, we recommend the use a 16mm chain as a minimum wherever practical.


Link Design and Dimensions

All of our Protector chains feature long-link design and are constructed from 16mm diameter bar.

The Protector 16mm chain links have nominal dimensions of: 132 x 62mm outside; 100 x 30mm inside, throughout its length which means that a special elongated end link is not required.

The use of long links throughout the length of the chain helps to reduce weight, while providing greater versatility and allowing the chains to be used with close shackle padlocks for maximum security.

The end link of the Protector 16 and 11mm long link chains can be looped through any intermediate link along the length of the chain. To pass a link through an intermediate link, you will need to cut a slit through the sleeve, but it offers the major advantage of being able to lock the chain tight against the item you are protecting, helping you to keep it off the floor, all of which makes it much harder to attack.

If choosing a ground anchor to use with your chain, choose one with a minimum aperture of around 65mm, as the sleeved chain is unlikely to fit easily through a smaller hole.

Overall chain lengths are also nominal, being subject to manufacturing tolerance as well as being potentially up to one link over or under the advertised length, because a whole number of links will invariably not be an exact number of metres or half-metres overall.

Please Note: as mentioned above, the link and chain length dimensions are nominal and may vary a little from batch to batch. If you are particularly tight in terms of the precise link dimensions or the precise length of a chain, please contact us and we will do our best to clarify details of current stock.

How to use your security chain for maximum effect

Wherever possible, keep your security chain off the ground, as this makes Cropping or Hammering type attacks much more difficult for the thieves.

Stewart Carter

I purchased this 16mm high security chain to secure my caravan to the ground in its storage area. This chain is rated as a CEN 6 security product, and you cannot buy better! This chain is also available in 19mm and a colossal 22mm size. It cannot be bolt cropped, and would take some considerable time to cut through with a disc cutter. The only problem is, to be careful lifting the chain as you may get a hernia as it is so heavy. This is probably the best security chain on the market!!
