Soft-Close Drawer Runners as Replacements for Mepla Kitchens

A soft-close drawer runner features an integrated hydraulic damper that slows down the drawer over the final few centimetres, closing it silently.

Many older fitted kitchens feature runner systems from manufacturers whose exact original parts are difficult to source today. When the rollers wear out, the drawer catches, or it slams loudly against the carcase when closed, it is time for a replacement. Retrofitting modern runners is a standard technical task in cabinet making. In this regard, fittings from Furnica serve as an exact alternative to Mepla and other established systems. This article explains the key technical criteria for identifying compatible replacement parts and installing them correctly.

What to Look for Regarding Compatibility

When replacing drawer runners, it is not the brand that determines fit, but the geometry of the carcase and the drawer box. The hole pattern in the side panel functions like a standardised coordinate system. In Europe, cabinet making is heavily standardised, which simplifies swapping fittings.

Two dimensions are essential when selecting replacement parts:

1. Nominal length: This is the exact length of the runner when closed. It is determined by the depth of the drawer. Typical lengths in kitchen environments range from 400 mm to 550 mm. The runner must never be longer than the internal carcase depth.
2. Installation width: This refers to the clearance between the outer side of the drawer box and the inner side of the cabinet carcase. For side-mounted runners, this dimension is usually exactly 12.7 mm per side.

Most kitchen cabinets are based on the System 32 standard. This means the pre-drilled holes in the carcase wall are spaced 32 mm apart vertically. The frontmost hole is positioned 37 mm from the front edge of the cabinet. If the existing Mepla runners utilise this grid, new drawer runners with soft close can generally be screwed in without drilling new holes into the carcase.

Suitable Runner Systems to Replace Mepla

Depending on the construction of the existing timber or metal drawers, various runner types are suitable as replacements. It is technically important not to confuse the damping mechanism (Soft-Close) with mechanical opening aids (Push-to-Open), as these utilise opposite mechanical forces.

Ball Bearing Runners

A ball bearing runner is screwed to the side of the drawer. A solid steel cage containing ball bearings ensures smooth travel. This variant is ideally suited as a sturdy replacement for old roller runners, provided the 12.7 mm installation width is present. For kitchen use, a full extension runner is recommended, allowing the drawer box to be pulled 100% clear of the carcase. A single extension runner, by contrast, only exposes around 75% of the depth. Corresponding full extension drawer runners offer the daily advantage in the kitchen of easily reaching pots and pans stored right at the back.

Undermount Runners

In modern kitchen construction, the runner sits concealed beneath the drawer base. The undermount runner supports the load from below and locks into place via front-locking clips. If the existing Mepla kitchen is already based on undermount technology, the new undermount drawer runners must match the existing wooden drawer box precisely in terms of nominal length and the rear hook position.

Retrofitting Complete Drawer Systems

If the old drawer box itself is damaged or warped, simply replacing the side runners is not enough. In this scenario, the entire box is replaced with compatible kitchen cabinet drawer boxes. These kits contain the runners, the metal drawer sides, and the front fixing brackets. The base and back panel made of chipboard must be cut to size.

Selection strictly depends on the external width of the kitchen unit with a standard carcase thickness of 16 mm or 18 mm:

• A kitchen cabinet drawer 60 cm is designed for standard cooker housing units or wide pan storage.
• A kitchen cabinet drawer 40 cm fits narrower base units, which are frequently used for cutlery or dry food storage.

Installation and Fitting of New Runners

Installation requires precise alignment. An offset of just a few millimetres will prevent the soft-close damper from engaging or cause the runner to bind.

Required tools:

• Cordless drill/driver
• Screwdriver with PZ (Pozidriv) size 2 bit
• Tape measure
• Try square
• Bradawl or 3 mm wood drill bit

Step-by-step installation:

1. Removal: Take out the old drawer and unscrew the Mepla runners from the carcase.
2. Check hole pattern: Measure the distance from the old drill holes to the front edge. If this measures 37 mm, the existing holes can be reused.
3. Fit the carcase profile: Secure the new runners into the row of holes using Euro screws (5 mm). Alternatively, use countersunk chipboard screws (4 x 16 mm). The runner must be perfectly level.
4. Fit the drawer profile: For ball bearing runners, disengage the release lever to detach the inner member of the runner. Screw this profile centrally along the outside of the drawer box.
5. Insertion: Align the drawer horizontally and slide it into the runner cage until the locking mechanism audibly clicks into place.

Complementary Replacement Parts: Hinges

When renewing runners in an older kitchen, cabinet doors often show signs of wear as well. Modern components here also serve as compatible alternatives for Mepla fittings. The classic concealed hinge for kitchen doors features a standardised cup drilling diameter of 35 mm.

For standard opening cabinet doors, 110 degree cabinet hinges are used. If the door fully overlays the carcase sides, a full overlay hinge is required. These fittings can also be brought up to modern standards by selecting cabinet hinges with soft close, preventing cabinet doors from slamming shut.

FAQ: Frequently Asked Questions on Replacing Drawer Runners

Can I replace old roller runners directly with soft-close ball bearing runners? Yes, this is technically straightforward, provided the side clearance between the drawer and the carcase wall (the installation width) is exactly 12.7 mm. The nominal length of the new ball bearing runner must match the depth of the drawer box.

What does load capacity mean for a drawer runner? The load capacity is stated in kilograms (e.g. 30 kg or 45 kg) and defines the maximum permissible total weight of the drawer itself plus its contents. For cutlery drawers, 30 kg is sufficient, whereas runners with a higher load rating should be chosen for deep pan drawers.

Do I need to adjust the front panels when switching to soft-close? No. The damping mechanism is built directly into the runner (typically as a small cylinder with a tension spring at the rear). The position of the drawer front remains unchanged. Gaps and alignment can be fine-tuned via the slotted holes on the runner or via the eccentric cams on the front fixing brackets of complete metal drawer systems.
