A router will be required for door(s) installation. Please click here to find our manufacturers care and decoration advice for this door. Product Advice: The supplied track will have a length equal to 4x the individual door width plus 100mm. Opening sizes; the best opening size to aim for is 10mm less in height and 20mm in width than your chosen door size so the door "covers" the full opening and more, we have listed these in the door size options but you can choose to fit them to a smaller opening width / height. The type of architrave used or existing can impact on visible clearances. Prices show the door and track combined cost, all prices are inclusive of vat and UK wide delivery which may be from 2 or more suppliers. Tracks are aluminium and have hanging brackets for a secure wall fixing, the top wall plate, pelmet top and pelmet facia are not included. There is a maximum 2051mm floor to top of track height requirement for all variations (if using a 1981mm high door) which includes some track adjustable tolerances for discrepancies to wall and floor levels, please note that the surface fix brackets are over and above these height requirements. Door will require a groove to be routered in the bottom of it to suit the floor guide, no bottom track required in order to allow for a clear threshold so there is no trip hazard encountered with this track. Be very careful when setting any handle position and the track "stop" to prevent hand injuries. All doors are 35mm thick and have a solid or semi solid core covered with a quality timber veneer or surface material for painted and white versions. See our full range of handles and fittings here. Any multiple door product, EG; door pairs, sliding double doors, folding doors or double pocket doors are individual doors put together as a product visual, please note we cannot guarantee that the veneers and colour will be an exact match but every care will be taken to provide you with the closest match possible.
