Staircraft explains how to install a door kit

Neil Wycherley, Head of Technical at Staircraft, looks specifically at how door kits make the installation process quicker and simpler.

Doors kits are an indispensable way of making sure that internal doors are installed correctly and that the end customer has trouble-free use. A typical door kit comprises the door itself, the frame (or lining), hinges and door stop. Each of these elements must be installed correctly to ensure the door operates smoothly.

Step 1 Openings should be made 66mm wider than the door and 52mm larger than the height to allow for any packing and adjustments needed. When fitting to a block wall it is recommended that a plywood sub liner is installed prior to plastering.

Step 2 Place the door lining on a flat surface whilst keeping in mind the handing required. Drill a pilot hole and then screw the head to the jamb using 32mm long fixings, making sure all parts are aligned correctly.

Step 3 Position the assembled frame into the opening, ensuring the hinge jamb is plumb first. Then follow up by making sure the head and latch jamb are also square.

Once this is done, fix the frame into place using the pre-drilled holes.

At this stage you may want to install a dummy door to make sure the frame is square and plumb.

Step 4 Before you fit the door stop, ensure that all fixtures have been inserted into the pre drilled holes in the Jambs. The Door stop has an offset to suit a 44mm and 35mm door. Ensure the doorstop is orientated the correct way to suit your door thickness.

Fix the door stops to all three sides. Secure the door stop by Pinning in place.

Step 5 Our door kits are supplied with hinges pre-installed onto the door ready to hang. Hinge pockets are also cut into the lining to avoid having to remove the hinge during redecoration.

Step 6 Remove male hinge from the door and install into precut pockets in the jamb, ensuring it is flush. Then install the keep into the pre-cut pocket.

Finally, check that there is a 2mm gap evenly around the door. There is a square adjuster plate on each of our hinges that is factory set to zero. This can be adjusted to -1mm, +1mm and +2mm by matching the nib on the plate to the corresponding number on the female hinge. This allows for any slight deviation in the fitting of the door frame.
