This 10mm thick hardened heavy duty cloth covered chain is a fantastic mid-range chain which is light enough to be easily carried but still extremely secure to deter would-be thieves and is ideal for securing your trailer or caravan to a ground anchor when in long or short term storage or overnight. The Square Chain boasts of being Art Approved and Sold Secure Approved (independent automotive testing bodies for security products), giving you peace of mind when your trailer is secured against theft. The cloth chain cover makes it easier to handle when fitting in cold weather and also provides a scratch proof covering against your ground anchor or docking station it is secured to.
