Fitting Door Handles on Backplate: A Complete Guide

A backplate handle carries the lever, and often the keyhole or privacy turn, on one elongated plate rather than on a separate round rose. Because the plate covers a larger area of the door face, this style of handle can also be a practical choice when replacing older door handles and you want to conceal existing fixing holes or marks.

What you'll need

Before you start, gather the basic tools and fittings so you can position and secure the handles without repeatedly stopping during the job.

• The backplate handle pack: Check that both handles, backplates, spindle and all required fixing screws are present before starting.
• A suitable screwdriver: Choose one that correctly matches the heads of the fixing screws supplied with the handles.
• A tape measure or ruler: This is useful for checking the spindle position and keeping the backplates aligned on both faces of the door.
• A pencil: Use this to mark the screw positions accurately before fitting the plates.

Step-by-step fitting

Once you have everything ready, work through the following steps carefully so the two backplates sit squarely and the lever operates without binding.

1. If you are replacing existing handles, remove the old backplate or rose set first. Check that the spindle and latch mechanism are in good condition and operate smoothly before fitting the new set. If you are still choosing a replacement, you can compare all door handles before starting the work.
2. Insert the spindle through the square follower in the latch mechanism. Centre it so that approximately the same amount protrudes from each side of the door, giving both lever handles enough spindle to engage securely.
3. Hold one backplate against the door with the spindle passing through the handle opening. Position the plate so it sits straight over the latch, then use the fixing holes in the backplate as a template and mark each screw position lightly with a pencil.
4. Move to the opposite face of the door and repeat the process with the second backplate. Check its position against the spindle and your measurements so the two plates will line up correctly when they are secured.
5. Fit the lever handles onto the spindle through each backplate, then bring both plates into position against the door together. Insert the fixing screws and tighten them gradually and evenly, alternating between fixings rather than fully tightening one side first. This helps keep the backplates level and reduces the chance of pulling the handles out of alignment.
6. Operate the handle several times from both sides of the door. The lever should move freely, return cleanly to the horizontal position and retract the latch fully before allowing it to engage again when released. If the lever feels stiff or fails to return properly, loosen the fixings slightly, check the alignment of the plates and spindle, and retest before considering the fitting complete.
