Anti-climb spikes along the full top rail of a mahogany horizontal-slat sliding driveway gate, removing the grab-and-pull climbing line while keeping the upscale wood-grain look.
Warm Wood, Hard Edge
A rich mahogany-toned horizontal-slat sliding gate closes off this driveway, its warm wood grain set into a clean black steel frame. Sliding gates leave a long, smooth top rail that is easy to grab and pull up on — exactly the line this installation hardens.
Anti-climb spikes run the full length of the gate's top rail. They sit low and dark against the frame, keeping the gate's upscale wood look while denying any handhold across its entire span.
