Overview

Sliding doors are great to use in small rooms where you don't have room for a swinging door. Learn how to install a sliding door into a stud wall. We show you how to attach the frame. See how to attach rollers to the door. We also show you how to position guides so the door slides smoothly. 

Steps

1Put the sliding door frame together

Knock out the spacer at the top of the frame and insert the sliding track into the cavity. Screw the track to the doorframe.  Hammer two nails into the top of the doorframe upright and put the opposite frame upright in place. Use two nails to hold it in place.

2Install the frame into your stud wall

In this video we are installing the door in an empty stud wall. If you already have plaster walls you are going to have to cut away the plaster.  Place the frame into the stud wall. Make sure it is flush to the outside of the studs so that when you put the plaster on there is no bulging in the wall. Use the nail gun to fix it in place.

3Use packers to support the frame

When fixing the other side to the frame make sure you position it 10mm in front of the stud so that when you put the plaster on it is flush with the edge of your frame.

Use your spirit level to make sure the edge of the frame is level. Pack the gap between the stud and the frame with Masonite packers. Nail it together. Make sure you have support at the top and bottom as well as through the middle.

4Attach the rollers and hang the door

Screw the roller base plates to the top of the door. Make sure they are 80mm from each end and in the centre of the door edge. Place your door in the frame and insert the roller pins into the base plate. Use the locking pin on the side to hold the roller in place. Adjust the height and plumb of the door using the spanner provided. Screw the door guides onto the floor so the door can slide evenly in and out of the cavity unit.
