How to install a sliding door

Sliding doors are a great solution to homeowners who require a type of door which will save space and is easy to use. Without the need to swing in and out, these doors highly optimise the space within your property plus, feature a hassle-free operation which can be effortlessly used by children and elderly people.

Sliding doors have many other advantages, including their practicality and decorative element. These doors create the sense of a larger doorway and eliminate the struggle of moving heavy furniture through narrow doors. Additionally, these types of doors feature a contemporary design and can be a great statement piece within a room.

However, even though you can purchase sliding door locks and latches, these types of doors don’t offer as much security as standard doors, thus they should be used for rooms which require privacy rather than security.

At Ironmongery Experts, we supply various sliding door kits so you can easily install your own sliding door, including double wardrobe sliding door kits, glass sliding door kits, cupboard sliding door kits, bifold folding door kits, single wardrobe sliding door kits and single pocket door kits.

Step 1. Firstly, read the instructions to ensure that all the kit materials are present. If there is anything missing from the kit which should be included, contact our team as soon as possible.

Step 2. Make the required carvings on the door to be able to fit the hardware.

Step 3. Then, you can fit the hardware to the door. Start by fitting the hanger plates (which come in the kit) to the top part of the door. These must be centrally placed and fitted with a specific distance apart, according to the instructions. Use a pencil to mark the pilot holes for each hanger and then, drill the holes. After drilling the pilot holes, fasten the screws and fully attach the hangers to the door.

Step 4. Install the guide channel (provided in the kit) to the bottom of the door by screwing it into place.

Step 5. After installing the guide channel, it’s time to install the track to the wall. Use the tape measure and a pencil to mark the location of the track height from the floor. Then, place the track against your markings and use a level to ensure the position is correct. Draw on the wall a line of the full length of the track and mark the hole positions of the track. Securely hold the track on the wall and fasten the wall fixings.

Step 6. Hang the door into position by lifting it up and hooking the hanger plates with the horseshoe hanging points on the track.

Step 7. Ensure that the door is positioned at the right height, adjust if required. The door can be adjusted by turning the bolts positioned on the track with a spanner.

Step 8. Install the door stops (supplied within the kit) to ensure that the door will not run out of the track. Choose a position for the door stops and fix them into place.

Step 9. Finally, install the floor guide on the floor. Place it centrally under the door and fasten the screws. Ensure everything is level and test if the door is operating properly.
