Genuine BMW E12 / E23 / E24 / E28 Front Door Lock Clamp – NOS – 51211848744

Genuine BMW New Old Stock retaining clamp for the front door-locking mechanism used on selected classic BMW E12, E23, E24 and E28 models.

This U-shaped clamp forms part of the front outer door-handle and locking mechanism. It is used to retain and correctly position the relevant component within the door-lock linkage assembly.

One clamp is used in each front door. Two clamps are therefore normally required per vehicle.

The original BMW packaging is included but shows considerable age- and storage-related wear, including:

• Torn and opened packaging
• Dirt and storage dust
• Discolouration
• Faded and damaged labels
• General deterioration of the plastic packaging

The clamp itself may show light storage marks and age-related surface discolouration. Supplied exactly as shown in the photographs.

Included

• Original aged BMW packaging shown in the photographs

Door handle, lock cylinder, connection rods, mounting hardware and other locking-system components are not included.

Important quantity information

This listing is for one individual clamp.

BMW specifies two clamps per vehicle—one for the left front door and one for the right front door.

Order two pieces when replacing the clamps in both front doors. The stated price is per individual clamp.

Installation recommendation

Before installation:

• Compare the new clamp with the original component
• Inspect the door-handle and locking mechanism
• Check all connecting rods and mounting points for wear
• Clean the installation area
• Confirm that the clamp seats securely in its intended position
• Check that the lock linkage moves freely after installation
• Test the interior and exterior door handles
• Test the key and central-locking system before reinstalling the door panel

Installation should preferably be performed with the interior door panel removed and by someone familiar with classic BMW door-locking mechanisms.
