What size chains work with the Squire Matterhorn Mini D-lock

Updated on May 18, 2026

The Squire Matterhorn Mini is a useful compact D-lock that has Sold Secure Gold approval.

It features a 13mm hardened steel shackle and it fits all of our Protector security chains.

The Matterhorn is commonly specified with the Protector 11mm chain. It not only works as a small portable lock to lock your bicycle frame but you can also then use the 11mm chain to lock your bicycle wheel and secure it back through the Matterhorn.

Bikers also like the Matterhorn as it works as a disc lock and can accomodate larger chains, such as our Protector 16mm chain.

Great products

Thanks for some great products. Your kit protected my bikes perfectly during a burglary a few years ago and it’s still going (extremely) strong.

Ben R

Still going strong

I bought from you once and only needed to buy once in 2016, but suffice to say that the 19mm bespoke length chain, and ground anchor installed according to Pragmasis instructions are still going strong, keeping my bike safe just off the street in Brixton, London.

Mr B

Wholly impressed

I would like to say I am wholly impressed with the ground anchors, chains and padlocks that I have purchased over the past few years and will always recommend you when the opportunity arises.

Top class service

This is a serious chain! I certainly feel more comfortable that my bikes are well secured. Very pleased with the service too. I phoned then placed an online order and my chain arrived the next day. Excellent product and 1st class service. Thank you!
