Retrofitting Soft-Close Dampers for Mepla Kitchens

Retrofitting soft-close damping to existing kitchen cabinets requires precision fittings that match the existing system in terms of 35 mm cup diameter, hole pattern, and mounting type.

Upgrading Older Kitchen Cabinets to Soft-Close

Older fitted kitchens often feature sturdy carcases, but mechanically they usually lack the modern standard of integrated closing dampers. When cabinet doors slam shut loudly or drawers crash unchecked into the carcase, modernising the fittings is the ideal solution. A complete replacement of the units is not necessary. By selecting the right replacement parts, you can bring the moving mechanisms up to modern standards.

When searching for a replacement for Mepla fittings or components suitable for Mepla kitchens, technical compatibility is key. Because furniture manufacturing standards have largely aligned over the decades, modern hinges and runners can serve as an alternative to Mepla original parts, provided the installation dimensions match precisely. A well-adjusted hinge operates like clockwork – the mechanism must align millimetre-perfectly with the drill holes in the timber to function smoothly.

Compatibility Considerations: Dimensions and Drill Holes

To ensure that new components are compatible with Mepla carcases, key parameters of the existing fittings must be measured prior to removal.

Cup Drilling and Hole Pattern on Hinges

The core element of door mounting is the concealed cup hinge. On most standard kitchen cabinets, the diameter of the circular recess routed into the door is exactly 35 mm. Smaller 26 mm variants are uncommon in kitchen fittings. In addition to the cup diameter, the hole pattern for the fixing screws is crucial. Many manufacturers follow System 32, where the drilling holes in the carcase are spaced on a 32 mm grid. The distance between the screw holes on the hinge cup typically varies between 45 mm and 52 mm depending on the model.

The Correct Mounting Type (Cranking)

A common mistake when replacing hinges is choosing the wrong cranking. The mounting type defines how the door rests on the carcase sides when closed:

• Full overlay: The door completely covers the cabinet side edge. The hinge arm is straight with no cranking.
• Half overlay: Two doors share a single carcase centre partition. The hinge arm has a moderate crank (usually 9.5 mm).
• Inset: The door sits flush inside the carcase opening. The hinge arm has a pronounced crank (usually 16 mm or more).

Drawer Runners: Length and Extension Type

When converting drawers, the nominal length of the runner must be measured. In kitchen cabinets, this typically ranges from 250 mm - 600 mm. In addition, you must decide whether to install a partial extension (drawer opens to about 75%) or a full extension (100% opening travel). The load capacity in kilograms is also a critical factor for pots, pans, and crockery.

Suitable Replacement Fittings for Retrofitting

Depending on whether you only want to add damping or replace the entire fitting, several technical solutions are available.

1. Complete Hinge Replacement

The cleanest approach is replacing old hinges with concealed cup hinges with integrated soft close. Here, the damping cylinder is built directly into the hinge arm or the cup. If the old carcase mounting plates no longer adhere to current standards, a set containing both hinge and cruciform mounting plate is recommended. For standard applications without damping, such as very narrow filler panels, standard concealed cup hinges are used.

2. Add-on Dampers

If you prefer to keep intact hinges on the carcase, separate door dampers can be installed. These are either clipped directly onto the hinge arm as clip-on dampers (requiring exact compatibility with the specific hinge model) or recessed into the front edge of the carcase as drill-in dampers. A simpler, purely acoustic solution against doors slamming hard is provided by self-adhesive silicone buffers and pads.

3. Converting Drawers to Soft-Close

Old roller runners can often be replaced with modern drawer runners with soft close. These feature a self-closing mechanism that catches the drawer over the final centimetres and pulls it gently shut. If you also want to improve access to the entire contents of the drawer, opt for full-extension drawer runners, ideally also equipped with a soft-close function.

4. Wall Units and Lift-Up Flaps

Many kitchens feature wall cabinets with upward-opening lift-up flaps. If these fall shut without braking or fail to stay open, the gas strut is usually worn out. Replacing it requires selecting the correct force rating, measured in Newtons (N). A gas strut must be matched precisely to the weight of the flap. For aesthetic integration with the cabinet interior, options such as the gas strut in silver are available.

Installation and Retrofitting: Step-by-Step

Retrofitting hardware is straightforward for experienced installers and confident DIYers with the right tools.

Required tools:

• Cordless screwdriver with suitable bits (usually PZ for chipboard screws)
• Folding rule or calliper
• Engineer's square
• Forstner bit (35 mm) if drilling new recesses

Replacing Hinges

1. Removal: Remove old hinges by loosening the fixing screws on the cruciform mounting plate.
2. Inspection: Measure the cup diameter in the door (35 mm) and the distance between the screw holes.
3. Fitting the mounting plate: Screw the new mounting plate into the carcase. If the hole pattern differs, new 5 mm holes must be drilled at a 32 mm spacing.
4. Inserting the hinge: Fit the new cup hinge into the door recess and screw it in place at a right angle.
5. Adjustment: Hang the door and align it precisely using the 3D adjustment screws (height, depth, and side overlay) on the hinge arm.

Retrofitting Drawer Runners

1. Measuring: Measure the internal depth of the carcase and the length of the existing runner.
2. Removal: Unscrew the old runners from both the carcase and the drawer box.
3. Positioning: Mark the position for the new ball-bearing runner on the inside wall of the carcase. Precise horizontal and parallel alignment is essential, as the soft-close mechanism may jam otherwise.
4. Fixing: Secure the runners using Euro screws or wood screws (4 mm diameter).
5. Testing: Insert the drawer and test the soft-close self-closing action several times.

Frequently Asked Questions (FAQ)

Can I use any hinge as a replacement for Mepla fittings? No. The new hinge must match the technical specifications required for Mepla drill patterns. The cup diameter (usually 35 mm) and the correct mounting type (full overlay, half overlay, or inset) are strictly required. The fixing screw hole pattern can, if necessary, be adapted by drilling new pilot holes into the timber.

What is the difference between push-to-open and soft-close? These two systems operate on opposing principles. Push-to-open (or tip-on) is an opening aid for handleless fronts: pressing the door triggers an internal catch that pops it open. Soft-close, by contrast, is a closing damper that catches the door or drawer as it shuts and pulls it gently against the carcase. In standard mechanical fittings, these two systems cannot be combined in a single unit.

How do I calculate the correct force for a gas strut? The force in Newtons (N) depends on the weight and height of the MDF or chipboard flap. As a rule of thumb: flap weight in kg multiplied by 10 gives the approximate Newton rating (e.g. 3 kg = 30 N). Because leverage comes into play, taller flaps require stronger struts. Do not confuse a gas strut (which supports the flap open) with a door damper (which cushions the closing movement).

Can partial-extension runners be easily replaced with full-extension runners? Yes, provided the installation clearance between the drawer side and the carcase wall is identical (often 12.7 mm or 27 mm for side-mounted ball-bearing runners). The full extension offers the advantage of allowing the drawer to extend 100% out of the carcase, greatly improving access to items stored at the back.
