Looking for an experienced handyman or carpenter with their own tools to install two Yale 3500 series hydraulic overhead door closers on-site: Door 1: Metal porta cabin entrance door (will require HSS/cobalt drill bits and self-tapping metal screws or rivnuts to secure cleanly into the metal skin/frame). Door 2: uPVC door (will require careful pilot drilling and appropriate uPVC/window-grade fixings so the profile isn't cracked or damaged). Please bring your own fixings suited for both metal and uPVC doors/frames. Once fitted, please adjust the closing and latching speed valves.
