Sill or threshold for door or window, has visible side with height designed to provide clearance for tenon in bottom side of door or window

摘要

The height (H) of the visible side (24) of the sill or threshold body (20) is specifically chosen so that the tenon (44) on the bottom side of the door or window can be passed over this body without coming into contact with it. The sill or threshold body includes an arm (22) for providing protection against the weather on the opposite side to its visible side.
