The stable installation of a wall anchor in the masonry of your house or garage provides security for your bikes. The WCH wall chain anchor neatly integrates anchor and chain into a high-security system - more secure, more cost-effective and easier to handle. You can have keys made with the same key code as your existing XPlus key code by request. The chains are available in different lengths and thicknesses. This way you can find the right chain for your needs. And when your bike collection grows, you can even chain multiple anchors together.
