Gate Stops / Jams are upright timber batten sections which are usually screwed to the to the posts, wall-plates or framework to help keep the gates/doors nice and true help help prevent against future movement. These give the gates and doors something to close against inside the opening. We recommend pre-drilling (evenly spaced) before applying the screws to prevent splitting. These are supplied in a smooth finish and are 20mm x 20mm. Available in untreated, Brown treated and Green treated, We usually supply these to suit whichever gate/door height you have purchase and are set at a set price.
