How to fit a door handle — step-by-step guide

Fitting a door handle is a job you can do yourself in 10-15 minutes, with no special tools.

What you need

• A no. 2 Phillips screwdriver
• A 2.5 mm Allen key — usually included in the box
• A ruler or calliper

Step 1 — Remove the old handle

1. Find the small screw on the rose (on the side or the inner face)
2. Loosen it with the Allen key
3. Pull the handle off the spindle
4. Unscrew the rose (2 screws) and take it off
5. Repeat on the other side and remove the square spindle

Step 2 — Check the dimensions

The new spindle should exceed the total thickness of the door by 5-8 mm. If it is too long, you can cut it with a hacksaw.

Step 3 — Fit the rose

1. Set the rose into the groove in the door
2. Fit the 2 screws — do not tighten fully, leave play for alignment

Step 4 — Insert the spindle and fit the handle

1. Push the square spindle through the lock opening
2. Slide the handle onto the spindle
3. Press until it reaches the rose
4. Tighten the Allen locking screw

Step 5 — The other side

1. Fit the rose on the other side
2. Slide the handle onto the spindle
3. Align both handles so they are parallel
4. Tighten the Allen screw and the rose screws on both sides

Final check

• The handle goes down and springs back to horizontal on its own? OK
• The latch goes in and out easily? OK
• The rose is firm, with no play? OK

Common mistakes to avoid

• Overtightening the Allen screw can jam the handle
• A spindle that is too short keeps the handle from engaging the mechanism properly
• Forgetting to align the handles before the final tightening

Tools and materials needed

You need: PH2 Phillips and flat-head screwdrivers (some Enger handles use Torx screws — check the box); a metal ruler to measure the axis distance and alignment; a pencil and an 8 mm wood drill bit (only needed for a new door without holes). Check the contents of the box: 2 handles, front and back roses, spindle, long fixing bolts, rose screws.

Preparation — what to check before you start

Check compatibility: the PZ axis distance must be the standard 72 mm; the locking type must match the lock (OB without cylinder, PZ with key, WC for bathrooms with a thumb-turn, BB with an inside button); door thickness — the standard 80 mm spindle included suits doors up to 45 mm; rotating handles on roses are universal left/right.

Fitting the rose and the cylinder

Step 1 — Remove the old handle: find the fixing screws (visible, or hidden under a decorative cap on the rose). Undo the long bolts that pass through the door, then pull the handles off. Step 2 — Remove the old cylinder: undo the fixing screw in the lock faceplate (visible on the edge of the door). Insert the key and turn about 30 degrees to extract the cylinder. Step 3 — Insert the new cylinder: with the cam slot aligned to the housing in the lock. Secure it with the faceplate screw. Do not overtighten — the cylinder must turn freely. Step 4 — Position the front rose: aligning its holes with the existing ones. A SLIM rose sits directly on the door surface, without spacers.

Fitting the handle

Step 5 — Push the spindle through the door: the 8 mm square spindle passes through the central hole of the lock. Orient it correctly — some spindles have a locking recess on one face only. Step 6 — Fit the front handle: slide it onto the spindle, align the fixing holes with the rose, insert the long bolts but do not tighten fully. Step 7 — Fit the back rose and handle: on the other side of the door, fit the rear rose, then the handle; align and insert the fixing bolts. Step 8 — Tighten the screws gradually: alternating front and back, a little at a time, so the rose stays flat on the door. Do not force — SLIM roses are zinc or aluminium and can crack if overtightened.

Adjustment and final check

• Test that the handle turns freely and springs back (the internal spring works)
• Check that the latch extends and retracts fully when you work the handle
• Test that the key works correctly in the cylinder from both sides
• Check that the rose sits flat on the door with no play or grinding
• Test with the door closed — the latch enters the strike plate without rubbing
