Once rollers are de-adjusted, most doors can be lifted from tracks easily. Others require fixed panel or head pelmet to be removed. Take care with panels containing glass.

Place the door carefully on its side. Some carriages & rollers can be removed by unscrewing any screws retaining the bracket or housing and then slide out. Others require the removal of bottom rail. Take car when removing corroded screws. Bring the roller and carriages into our shop for the correct roller.

They are replaced in the same manner as they were removed. Refit bottom rails if required. Remember to replace the glazing vinyl onto the glass before refitting the bottom rail.

Before refitting your door, it is important to reshape damaged tracks to suit new roller shape.   Failure to reshape the track or remove any burs can cause premature wear. Run the file lengthways down the track in a sweeping motion. Rotate the file with each stroke to recreate the dome shape on the track. Clean dirt and grease from the track area.

It is important to adjust doors so that it is parallel to the frame on the lock side. To avoid undue stress to the carriages and rollers, take weight off door during adjustment. Adjust to lock in the door’s new position.

Care should be taken to avoid breaking glass. Don’t force any locks or carriages. Examine component installation to avoid breakage on removal or refit. Don’t use grease, soap, lubrication sprays, or powders as they only attract dirt.
