Introducing : Hiplok DXXL 

Hi There, Thanks for your feedback! This is something we are looking at filming in the future. In the meantime, I hope the following information helps. The DXXL is two parts a D Lock and an Open-Ended Loop Chain. The Loop Chain is designed so the smaller looped end of the chain can be passed through the larger loop. This creates an adjustable loop that can be looped around either part of your bike or a locking point. hiplok.com/product/hiplok-xl-chain/ Image on the product page shows this. The D lock is then passed through the smaller chain link and can be used to lock either the bike or the locking point. You could also use the D Lock to secure your bike to a rack like usual and use the looped chain on either side of the U-shaped shackle to lock accessories. I hope this helps.
