Our products are manufactured here in the UK using quality materials. All of our products offer a very high visual deterrent and are designed to give maximum security. Most of our products usually have several security features incorporated into each product. Crookstoppers products come fully galvanised so that you do not have to worry about any rusting, flaking or chipping issues. Products that we do not produce such as tow balls and fixings will come either chrome plated or electroplated.

Here at Crookstopper we have so much faith in our ultimate security products that they come with a 10 year guarantee.
