Retrofitting Door Dampers & Soft-Close as a Replacement for Mepla Hinges

A door damper mechanically cushions the cabinet door before closing, while a modern concealed hinge with integrated soft-close completely and functionally replaces old Mepla hinges.

Anyone repairing older kitchen cabinets or wardrobes frequently comes across fittings from the Mepla brand. Because this manufacturer no longer operates under its own name on the market, sourcing exact original replacement parts is often difficult. For joiners and fitters, this presents a clear technical task: either upgrade the existing, still functional hinge with a separate door damper, or replace the old component entirely with a contemporary hinge.

A hinge without soft-close acts like an unbraked car door – it slams into the carcass with full force. To stop this wear and tear and improve user convenience, replacement requires precise knowledge of cup dimensions, overlay types, and mounting techniques.

The Main Buying Criteria for Replacing Mepla Hinges

When replacing furniture fittings, the physical parameters of the old hinge must be analysed precisely. Only then can a compatible replacement fitting be determined.

The Cup Diameter

The concealed cup hinge is the standard in furniture construction. In most Mepla hinges and modern alternatives, the cup routed into the door has a diameter of exactly 35 mm. Rare exceptions for very lightweight doors use a 26 mm cup. The drilling depth for the 35 mm cup is usually 11.5 mm to 12.5 mm.

The Mounting Type

The position of the door in relation to the carcass side panel defines the required hinge. Choosing the wrong type will cause the door not to close or to bind.

• Full overlay: In the closed position, the door lies almost completely over the front edge of the carcass side panel. The crank angle of the hinge arm is minimal here (0 mm).
• Half overlay: Two doors share a central carcass divider. Each door covers the front edge by only half (approx. 8 mm to 9 mm). The hinge arm has a medium crank (usually 9.5 mm).
• Inset: The door sits flush inside the carcass. The front edges of the carcass side panels remain fully visible. The hinge arm has a high crank (usually 16 mm to 18 mm).

The Opening Angle

The angle determines how wide the cabinet door swings open.

• The standard for regular cabinet doors is 110°. Corresponding concealed hinges / cabinet hinges 110 degrees cover most applications.
• For corner cabinets with bi-fold doors, special angles are required; concealed hinges / cabinet hinges 135 degrees are frequently used here.
• If internal drawers are positioned behind the door (e.g. in a larder unit), the door must swing completely clear of the internal opening. For this, concealed hinges / cabinet hinges 155 degrees or wide-angle hinges with 165° are strictly necessary.
• For angled carcases (sloped ceilings, corner solutions), the fitter uses angled hinges, such as concealed hinges / cabinet hinges 45 degrees or concealed hinges / cabinet hinges 30 degrees.
• For blind corner constructions (post constructions), one relies on concealed hinges / cabinet hinges 90 degrees.

Overview of Types and Options: Retrofitting vs Complete Replacement

When dealing with an old Mepla fitting, there are two technical routes to modernise the closing action.

Option A: Retrofitting Separate Door Dampers

If the old hinge is still mechanically sound (no play in the joint, spring intact), fitting add-on dampers is sufficient. These door dampers absorb the kinetic energy of the closing door.

• Piston dampers (bore-in): Drilled directly into the front edge of the carcass side panel. Requires a precise wood drill bit (usually 10 mm diameter) and an exact drilling depth (e.g. 50 mm). The result is visually unobtrusive.
• Surface-mounted dampers: Screwed inside the cabinet onto the carcass side or the top panel using an adapter plate. Usually secured with a cross-recess drive (PZ). If necessary, their damping force can be adjusted via a regulating screw.

Option B: Complete Hinge Replacement (Soft-Close)

If the Mepla hinge squeaks, sags, or is defective, it must be replaced. Modern concealed hinges / cabinet hinges with damping (Soft Close) have the hydraulic cylinder built directly into the hinge arm or the cup. The benefit lies in the concealed mechanism and the elimination of extra add-on components inside the cabinet.

Important: Soft-close must never be confused with the push-to-open mechanism. Soft-close is a damper that slows the door down upon closing. Push-to-open (or tip-on) is a spring mechanism that pushes handleless doors open when pressed. Both systems work in opposite directions and are generally mutually exclusive on the same hinge.

Which System for Which Scenario? (Decision Guide)

The choice of the right repair method depends on the condition of the furniture components and the desired level of effort.

• If the old Mepla hinge is still firmly seated and the door does not sag, then a separate surface-mounted damper is the fastest and most economical solution.
• If the cabinet door creaks during opening or the closing spring is broken, then the old fittings must be replaced with new concealed hinges / cabinet hinges.
• If the door is very heavy (e.g. large MDF fronts from 22 mm thickness upwards), then hinges with integrated damping should be chosen, and if needed, damping on the hinge arm can be activated or deactivated to achieve a synchronous closing motion.

Fitting Guidelines for Hinges and Dampers

Replacing a hinge requires precise work and the correct tools.

Required tools:

• Cordless screwdriver
• Pozi screwdriver bit (PZ2 for woodscrews)
• Wood drill bit (3 mm for pilot holes)
• If applicable, Forstner bit (35 mm) for completely new drillings
• Folding rule and try square

Step-by-Step Replacement:

1. Dismantling: Remove the old door. With Mepla hinges, a locking screw on the hinge arm often needs to be loosened before the door can be pulled off the mounting plate.
2. Checking dimensions: Measure the diameter of the cup hole in the door (target: 35 mm).
3. Removing the mounting plate: Unscrew the old cruciform mounting plate from the carcass. Modern mounting plates frequently utilise System 32, where the screw holes are spaced 32 mm apart vertically on the cabinet side. The standard setback from the carcass front edge is 37 mm.
4. Inserting the new hinge: Insert the new concealed hinge into the 35 mm hole in the door and align it square.
5. Adapting the hole pattern: The drilling pattern for the fixing screws on the cup (usually 45 mm or 52 mm spacing) often differs from the old Mepla holes. In this case, ignore the old holes, align the hinge straight, and pre-drill approx. 2 mm deep with a 3 mm drill bit. Then secure with 3.5 x 15 mm woodscrews.
6. Fitting the cruciform mounting plate: Screw the new mounting plate into the carcass.
7. Hanging and adjusting the door: Modern hinges feature clip-on technology. The door is simply pressed onto the mounting plate until it audibly clicks into place. Afterwards, carry out 3D adjustment using the adjustment screws on the hinge arm (aligning reveals in height, lateral position, and depth).

Frequently Asked Questions (FAQ)

Can I replace Mepla hinges 1:1 with new hinges? No, an exact 1:1 replacement without drilling new screw holes is rarely possible. While the 35 mm cup drilling in the door almost always matches, the hole pattern for the small cup fixing screws and the position of the mounting plate on the carcass often differ by a few millimetres depending on the new manufacturer. Pre-drilling with a 3 mm wood drill bit is usually required.

How many door dampers do I need per cabinet door? For standard kitchen doors (up to approx. 900 mm high and 600 mm wide), a single door damper or a single hinge with activated soft-close is generally sufficient. For very tall or heavy doors (e.g. full-height wardrobe doors), two dampers should be installed – one in the upper third and one in the lower third of the door.

Do modern hinges fit onto old Mepla mounting plates? No. The attachment mechanism on the hinge arm (clip system or slide-on system) is manufacturer-specific. A new concealed hinge strictly requires fitting the supplied, matching cruciform mounting plate inside the carcass.

What is the difference between a standard concealed hinge and a wide-angle hinge? A standard concealed hinge opens the door to approx. 110°. A wide-angle hinge, such as concealed hinges / cabinet hinges 165 degrees, allows the door to fold back almost completely. This is technically necessary when internal pull-outs or drawers are situated behind the door, as they would otherwise catch against the door edge when pulled out.

Can I retrofit soft-close to existing fittings without drilling? Yes, there are clip-on dampers that snap onto the hinge arm without tools. However, these are strictly manufacturer- and series-specific. For obsolete Mepla hinges, such specific clip-on dampers are virtually unobtainable, making universal surface-mounted dampers the proper trade alternative.
