Aluminium door handles with a 48mm pz centres measurement are commonly found in residential entrances with aluminium door profiles. Over time, these handles may require replacing due to weathering, wear and tear or a desire for a fresh look. In this step-by-step guide, we will walk you through the process of replacing door handles for aluminium door profiles. Specifically, we'll cover handles to suit aluminium door locks from brands like ABT, Yale, Union, and Scope that use a clip-on mechanism over plastic blocks already mounted on the door similar to the ones pictured below.

Step 1: Locate and Loosen The Grub Screw
Locate the Grub Screw
Identify the internal handle, which is the one you use to open the door from the inside.
Look for the grub screws on the inner or underside of the lever that holds the spindle. These screws secure the handle in place.
Loosen the Grub Screw
Use the appropriate screwdriver to carefully undo the grub screws. This will loosen the handle on the spindle and allow you to remove it.
Step 2: Unclip the Internal Handle Cover
Access the Screws
To access the screws holding the handle cover in place, you need to unclip the cover.
The cover is clipped onto black plastic blocks fixed to the door located at the top and bottom of the handle.
Unclip the Handle Cover
Gently insert a small flat-bladed screwdriver behind the cover at both the top and bottom.
Apply gentle pressure to carefully prise off the cover.
Be extremely cautious during this step to avoid damaging the handle or the door. The plastic blocks are prone to cracking if too much force is applied.
Once the plastic blocks are off, you will see the bolt-through fixings.
Remove the Old Handle
Carefully unscrew and remove the bolt-through fixings that hold the old handle in place.
Keep track of the screws and fixings for reuse or replacement.
Considerations if replacing the existing Door Handle
Inspect the Bolt-Through Fixings
With the handle cover removed, you will now see the bolt-through fixings that secure the handle to the door.
Inspect the fixings to ensure they are in good condition. If any are damaged or corroded, consider replacing them.
Inspect the Spindle
While you have the handle removed, inspect the spindle that connects the handles on both sides of the door.
If the spindle is rusty or stuck, apply lubricating oil and gently work it to free it up.
Address Handle Drooping
If the handle is drooping, check the spring cassette. If it's in good condition, the issue might be with the handle follower.
Handle Follower Replacement
If the handle follower is worn, you can resolve the problem by using a spindle sleeve with a diameter of 8-9mm. This will compensate for any wear and ensure a snug fit.
Installing a new replacement handle set
We recommend when selecting a replacement handle set, you choose one with a slightly larger backplate width and length than the old handle you are replacing. This will ensure any scuff marks or general wear and tear mess is covered up by the larger backplate. Where possible select a replacement door handle set with the same distance between the screw centres as the old handle set to avoid needing to create new screw holes.
1. Position the New Handle
Align the new handle with the bolt-through fixings on the door.
2. Secure the New Handle
Make sure the handle is properly aligned and secured. Insert and tighten the bolt-through fixings to secure the new handle in place.
3. Test the Handle
Gently test the handle to ensure it operates smoothly and locks properly.
