Exitex Macclex 15/56 Thermal Break Threshold - Various Sizes & Finishes

Fitting Instructions: Remove rubber seals from aluminium sill section. Check width between inside faces of the doorframe rebate and cut aluminium section to this size, cutting at the opposite end to the replacement seal hole. Cut the rubber seals 10mm longer than the aluminium and reinsert into the grooves in sill. Notch both ends of sill and allow it to fit into the doorframe rebate. When the door is in the closed position the front seal should be compressed by approximately 3mm. Notch sill to allow for this. This sill requires an under door clearance of 12mm. If necessary, remove door and trim to allow for this, ensuring bottom of door is smooth to avoid damage to rubber seals. Position the assembled sill between the doorframe and the mark fixing points through countersunk holes. Remove sill, drill fixing holes and insert plugs. Apply sealing compound to underside of sill where sill comes into contact with the doorframe. Screw sill into place.
