    Product Description

    This is the famous  5/8" - 16mm hardened boron steel Protector chain in 6-1/2ft - 2m length, made in the UK.
    Sold Secure Motorcycle Gold standard approved by Great Britain's independent Sold Secure testing house.
    Guaranteed to be bolt cut proof with any hand operated cropper, even Irwin's massive 42" monster cutter.

    Protector 16mm is lighter and has smaller links (better handling) than its 19mm bigger sibbling. Still one of the highest-approved chains available anywhere, made from high grade European raw material and put through a specific hardening process to become hard enough to resist cutters and saws yet flexible enough to withstand freeze and prying methods.

    Combined with the German made ABUS 37/80 padlock, or the ABUS 58/140 HB III 100 16mm U lock, you create a security system impervious to any quick 'cut and getaway' method. In other words, bring a big enough grinder for this one and expect to spend some time making lot's of noise and sparks. Even if an enterprising thief is able to cut through all this hardened steel, he will have to cut a chain link twice.

    Package deal: We are offering this chain, combined with German made 37/80 padlock or the very secure RotaLok, at a strongly reduced combined price.
    In addition, you can use the SHIP coupon at checkout. Depending on where you are located, this will give you free or strongly reduced shipping cost.

    Do I need 13, 16 or 19mm chain?
    This depends on where and what you are locking up. Keep in mind the total weight for chain and lock (see below for chain weight and any decent lock starts around 3Lbs). Due to weight and size, the 19mm Protector chain is for stationary use only, it is simply too heavy to carry around. 16mm is still very heavy and not really designed to take with you. 13mm is light (compared to 16 and 19) while still providing serious security. If you need a portable solution, stay within the 10 to 13mm range. If weight is not an issue, depending on your security needs, go between 14 and 19mm.

    What length do I need?
    The main advantage these long link Protector chains have, besides being ridiculously strong, is that any link can be interlinked anywhere in the chain (13 and 16mm chains only, not the 19mm version). This means that you can make loops at each end, working with 2 locks (or permanently attach the chain on one end), rather than looping the chain in a full circle with one lock. Less chain length is less weight and much easier to work with.

    I see 16mm chain offered from other brands, often with lock included and at a lower cost. What is the difference?
    Pretty much all other other brands on the US market use China made chain. Their steel composition and hardening process is usually mediocre at best. Look at the welding on a China made chain, then look at ours. As for included locks ... some of those included locks carry impressive names but look more like a joke to us.

    Reviewer: J. Alex Santos (Monroe, NJ)

    I researched security options for my bimmer for a good long time. I heard about these chains and another one from England (both are made there) but the Protector (perfect name for it) was the only one available in the US. I use the layered security approach and decided to put as many layers as I possibly can. I completed the first 4 of 6 layers after receiving the 16mm-6.2' chain. When I received it I thought what the heck would I need other layers? This thing is a fully-certifiable beast, a brute-hulk of indestructible high-quality British steel alloy! Seriously, the appearance alone will deter any would-be evil doer. I matched it with the Rota-Lok and they are a perfect match although the Squire combo they offer with the chain is just as effective. I realize any driven thief can and could take what they want. So, making this supremely difficult for them must be your goal! I firmly believe this chain and lock combo performs this task easily. I have been using my setup for about 2 months, I am glad nothing has happened but the peace of mind is my reward and the knowledge that my baby will be safe and sound when I come for her. That, in itself, is proof-positive that this was the right investment/choice. Read the reviews online on these Protector Chains and do yourself a favor, if you don't want to wake to find your baby missing, invest in this. It is not cheap but how much do you value your bike and your sanity? Pat from Lockitt was also very helpful and courteous. Thank you Pat! I assure you this won't be my last purchase! PROS: An absolutely perfect deterrent, value for peace of mind CONS: a resounding NONE
