Even very simple devices can be improved with some intelligent design work. Our Improved kick stop has different hook shapes to suit the back bone and the flank - the backbone hook is longer, and has a red cap to distinguish it. The length-adjustment knobs are a large, easy-to-use 9mm diameter, and are offset from centre so they are not accidentally depressed by contact with the shed breach rail. The end caps are of a new firmer material which will not come off so easily. All heavy duty galvanised steel. Maximum opening 70cm.
