Full Extension Runners as Replacements for Mepla Kitchens

A full extension runner allows 100 per cent access to the drawer contents, whereas a partial extension stops at around 75 per cent – a crucial technical detail when replacing defective runners in older kitchen systems.

Many established kitchens fitted years ago are equipped with Mepla hardware. When these mechanical components wear out after intensive use, fitters and joiners face the task of finding suitable replacements. Since the original components are often no longer manufactured in the exact same format, finding a technical alternative to Mepla is unavoidable. Modern runner systems and hinges can easily be used as Mepla replacements, provided the installation dimensions, hole pattern, and load capacity match precisely.

This guide explains the technical requirements for professionally replacing drawer runners and concealed cup hinges to restore furniture functionality.

Key Compatibility Considerations

Replacing a runner system is similar to replacing railway tracks – the gauge and fixing points must correspond precisely to the existing infrastructure. To find a suitable replacement for Mepla runners, three technical parameters are decisive:

1. System 32 and the Hole Pattern

Most industrially manufactured kitchen cabinets are based on System 32. This means the drill holes in the cabinet side panels have a vertical spacing of exactly 32 mm. The distance from the front row of drill holes to the front edge of the cabinet is standardly 37 mm. When installing new kitchen cabinet pull-outs, they generally rely on this standardised grid.

2. Nominal Length and Installation Width

The length of the runner (nominal length) must match the depth of the drawer. Typical lengths in the kitchen range from 250 mm - 600 mm. Additionally, pay attention to the lateral clearance (installation width) between the drawer side and the internal cabinet wall. For a classic ball-bearing runner, this is often exactly 12.7 mm per side. An undermount runner, on the other hand, is fitted invisibly beneath the drawer base and requires different routing on the timber drawer box.

3. Dynamic Load Capacity

Kitchen drawers are subject to heavy loads. While a load capacity of 30 kg is often sufficient for cutlery drawers, heavy-duty runners with 45 kg or more should be selected for pan drawers or an integrated pull-out kitchen waste bin.

Suitable Replacement Hardware for Various Cabinet Widths

When retrofitting, the cabinet width determines the choice of drawer box, but the side runners remain identical in function. Modern runner systems are compatible with Mepla cabinets across various standard widths.

Different configurations are used depending on the existing cabinet dimensions:

• A kitchen cabinet pull-out 60 cm is the standard size for hob base units and large pan drawers. A full extension runner is essential here to reach heavy pots stored right at the back.
• A kitchen cabinet pull-out 50 cm is frequently used for sink base units or larder units.
• A kitchen cabinet pull-out 40 cm is often positioned next to the cooker, ideal for spices or smaller utensils.

After successfully installing the new runners, the gained storage space can be organised with a tailored kitchen drawer organiser.

Replacing Hinges: Concealed Cup Hinge Compatibility

Alongside drawer runners, cabinet door hinges are also frequently subject to wear and tear. Anyone searching a Mepla hinge catalogue or looking for specific models such as a Mepla hinge 17m with spring will discover that a direct like-for-like replacement with identical legacy parts is difficult. Modern fittings serve as an exact alternative to Mepla.

Pay attention to the following specifications when replacing hinges:

• Cup diameter: The standard for kitchen hinges is a concealed cup hinge with a drill hole diameter of 35 mm.
• Opening angle: Older models often feature an angle of 110°. This standard is easily covered by current hinges.
• Door overlay type: Check how the door sits on the cabinet carcass. A full overlay is used when the door fully covers the cabinet side. A half overlay is used for twin doors sharing a central dividing partition.

Installation and Retrofitting of Runners

Installing new runners requires precision and the correct tools.

Required tools:

• Cordless screwdriver
• Screwdriver with PZ (Pozidriv) or TX (Torx) drive
• Tape measure or folding rule
• Spirit level
• Bradawl
• Matching countersunk wood screws (e.g. 3.5 mm or 4 mm diameter)

Step-by-step installation:

1. Removal: Remove the old drawer and unscrew the defective Mepla runners from the cabinet carcass.
2. Measuring: Check the existing hole pattern. Use the front hole at a distance of 37 mm from the front edge as your reference point.
3. Fitting the cabinet profile: Align the new runner profile horizontally and screw it into the system holes. Ensure the screw heads sit flush to prevent jamming the rollers or ball bearings.
4. Fitting the drawer profile: Attach the matching component to the drawer side (for ball-bearing runners) or under the base (for undermount runners).
5. Insertion and adjustment: Slide the drawer into the cabinet. Modern systems engage with an audible click. Check the smooth running and, if necessary, adjust the tilt using the adjustment dials on the locking device.

To give the refurbished kitchen the finishing touch, the kitchen furniture handles can also be replaced during the repair, provided the hole centres on the fronts match.

Frequently Asked Questions (FAQ)

Can I replace Mepla hinges with modern concealed cup hinges? Yes, this is generally straightforward. The crucial point is that the new hinge must be selected to match the existing cup diameter (usually 35 mm) and the overlay type (full overlay, half overlay, or inset) must be identical. The mounting plate (cruciform mounting plate) must also match the existing hole pattern.

What is the difference between soft-close and push-to-open? These two mechanisms serve opposite functions and must not be confused. Soft-close is a dampening system that catches the momentum of the drawer or door upon closing, pulling it shut gently and quietly. Push-to-open (or tip-on) is a release mechanism for handleless fronts that pushes the drawer open slightly when light pressure is applied to the front.

What load capacity do I need for my kitchen runners? For standard drawers holding cutlery or light provisions, a dynamic load capacity of 30 kg is sufficient. For wide pan drawers or pull-outs storing heavy plates and pans, a system with a 45 kg or 50 kg load rating is strongly recommended to prevent sagging or jamming.

What is the difference between roller runners and ball-bearing runners? A roller runner uses plastic wheels running in an epoxy-coated steel profile. It usually offers only a partial extension. A ball-bearing runner consists of interlocking telescopic steel profiles with steel ball bearings. It operates more precisely, supports higher loads, and is standardly engineered as a full extension runner.
