Hydraulic SureClose® Gate Closers & Hinges are designed to replace conventional, bulky commercial gate hinges and closers. These strong and sturdy hinge-closers provide smooth, bind-free performance. Superb engineering and patented design allow clever concealment of the hydraulics in a remarkably small housing. There is no compromise of quality with these small-footprint SureClose® gate closers and hinges. Each 'ReadyFit' model lives up to its name by providing convenient screw slots and holes for sturdy fixing. 25mm x 12g self-drilling Tek screws are supplied. The slots allow fine vertical adjustment for speedy gate alignment. Horizontal adjustment is attained by way of a built-in, adjustable locking ring that rotates in or out as required to ensure the gate is level and overall alignment is achieved. It’s remarkably simple for a commercial-style gate closer product. All SureClose® Hinges and Closers are made of high-grade aluminum.
