Replacement Parts & Compatible Fittings for Mepla — An Overview

Compatible replacement parts for Mepla fittings rely on standardised dimensions such as the 35 mm cup diameter and System 32, allowing defective components to be replaced with accurately fitting alternatives.

Older kitchen cabinets, living room wall units, or bedroom furniture are frequently fitted with hardware from the Mepla brand. When a concealed hinge wears out after years of use, the spring breaks, or the soft-close mechanism fails, a complete replacement of the mechanism is required. As historical product catalogues from the manufacturer are often no longer up to date, the search for a Mepla replacement focuses primarily on the technical specifications of the existing routings and drill holes.

This guide explains how fitters and experienced DIYers can determine the correct dimensions to select compatible hinges and fittings and install them professionally.

What to Look for Regarding Compatibility

To find a suitable replacement part, the physical characteristics of the old fitting must be measured precisely. The part number on the old hinge (for example, markings for a 17m hinge with spring) is helpful, but the actual dimensions on the piece of furniture are decisive.

The Cup Diameter and Hole Pattern

The concealed cup hinge is the central connecting element. Measure the diameter of the round recess routed into the furniture door.

• 35 mm: The absolute standard dimension for most kitchen and living room cabinets.
• 26 mm: Found less frequently, usually on very lightweight or small doors.

In addition to the diameter, the distance between the fixing screws on the hinge cup is relevant. Common spacings are 45 mm, 48 mm, or 52 mm. Replacing a hinge works like a modular system – as long as the grid dimension matches, the new components will fit seamlessly into the existing drill holes.

The Door Overlay Type

The position of the door relative to the carcase side determines the crank of the hinge. This must match the old Mepla hinge exactly:

• Full overlay: When closed, the door rests fully over the cabinet side panel. The hinge is straight and has no crank.
• Half overlay: Two doors share a single central carcase partition (twin application). The hinge features a slight crank (usually 9.5 mm).
• Inset: The door sits flush inside the carcase side panels. The hinge has a large crank (usually 16 mm).

Opening Angle and System 32

For standard doors, an opening angle of 110° is generally used. For special applications, such as corner cabinets with bi-fold doors, angles of 155° or 165° are required.

The mounting plate (often designed as a cruciform mounting plate) is fixed to the interior of the carcase. This is where System 32 typically comes into play. This means that the distance between the pre-drilled holes in the cabinet side is exactly 32 mm. Compatible replacement mounting plates use this exact hole pattern.

Matching Alternatives and Furniture Components

A broken hinge is often the prompt to thoroughly upgrade the functionality of a piece of furniture or bring it up to modern standards. When looking for fittings compatible with Mepla, it provides an ideal opportunity to upgrade from unsprung or standard hinges to soft-close alternatives.

This approach applies to all interior cabinetry. For example, when updating kitchen fronts, you do not have to limit yourself to repairing standard opening doors. For top cupboards that open upwards, flap fittings offer a mechanical alternative. For particularly heavy MDF or solid timber fronts in the kitchen, gas struts for heavy flaps provide the necessary lifting assistance. The force is measured in Newtons (N) and must be matched precisely to the door weight.

Internal fittings can also be upgraded during a repair. Anyone wanting to use the space above the sink more efficiently can install a plate drying rack for wall cabinets inside the repaired wall unit. When connecting the worktops below, robust worktop connectors are used.

The compatibility rules for hinges apply equally to the living room and bedroom. Whether adjusting the doors on a sideboard for TV, assembling a lowboard for TV, or repairing heavy mirrored doors when servicing a wardrobe for 2 people: the 35 mm cup diameter and the 32 mm hole pattern remain reliable constants for identifying suitable replacement fittings.

Installation and Retrofitting: Step-by-Step

Replacing a hinge requires precision, but it can be completed using standard tools.

Required tools:

• Cordless screwdriver or manual screwdriver with a PZ drive (Pozidriv, size 2)
• Folding ruler or calliper
• If necessary, wood drill bits (3 mm or 5 mm) and wood glue

Installation steps:

1. Dismantling: Loosen the screws of the old mounting plate on the carcase wall. Lift the door away and then unscrew the hinge cups from the door.
2. Dimension check: Check whether the 35 mm cup of the alternative fits flush into the routed hole in the door.
3. Fixing the hinge cup: Insert the new hinge. Ensure it is aligned precisely at a right angle to the door edge. Secure it with chipboard screws (usually 3.5 x 16 mm or 4 x 16 mm).
4. Fitting the mounting plate: Screw the new cruciform mounting plate into the existing 32 mm system holes in the carcase.
5. Hanging and adjusting the door: Clip or slide the hinge onto the mounting plate. Use the adjustment screws on the hinge arm to precisely adjust the door in height, depth, and lateral alignment (gap reveal).

Note: Never combine old Mepla mounting plates with new hinge arms from other manufacturers. The clip-on or slide-on mechanisms are not cross-compatible. Always replace both components as a set.

FAQ – Frequently Asked Questions About Replacement

How do I find a suitable replacement for a Mepla hinge with a 110° opening angle? Measure the cup diameter in the door (usually 35 mm) and check the overlay type (full overlay, half overlay, or inset). Then search for a standard concealed hinge with 110° and these exact parameters.

What should I do if the screw hole pattern on the hinge cup does not match exactly? If the old screw holes in the door (e.g. at 52 mm spacing) do not match the new hinge (e.g. 45 mm spacing), fill the old holes with wooden dowels (or matchsticks) and wood glue. Once cured, pre-drill the new holes with a 3 mm drill bit and securely fasten the hinge.

Can I replace an old hinge without soft-close with a soft-close version? Yes. As long as the basic dimensions (35 mm cup diameter, overlay type) are identical, you can easily install an alternative with an integrated soft-close mechanism to improve the closing action of the furniture.
