Installing frames and doors: Frame preparation: Locate the frame at the door opening, and attach base anchors to the floor on each jamb. Frame alignment: Use toggle blocks to maintain alignment during installation. Frame level and square: Ensure the frame is level and square. Frame clearance: Leave enough space for the door to swing, and some clearance on all sides. Door hand: Consider which way the door will be handed, as having the handle on the wrong side can damage walls and paintwork. Hinge attachment: You can attach the hinges to either the door or the frame first, depending on your preference. Plugging and trimming: After the door lining is fixed, insert plugs into screw holes and trim them to blend the wood.
