Retrofitting Drawers for Pelipal Kitchen Cabinets

When retrofitting drawers in existing cabinet systems, the hole pattern pitch, typically the System 32 standard, determines the seamless compatibility of the drawer runners.

Replacing or Adding Drawers in Kitchen Cabinets

When upgrading the functionality of existing kitchen cabinets, replacing or adding drawers is often the primary focus. In base units especially, drawer solutions offer significantly better ergonomics than simple shelves. Anyone looking for fittings suitable for Pelipal kitchens or similar established cabinet systems must adhere to strict technical specifications.

Replacing drawer runners or complete drawer side systems becomes necessary when old runners are worn out, the load capacity is no longer sufficient for heavy cookware, or comfort needs to be enhanced with modern dampening mechanisms. Since most industrially manufactured kitchen units are based on standardised dimensions, manufacturer-independent replacement parts can be fitted without problems, provided the installation width and cabinet depth specifications match precisely.

Key Compatibility Factors to Consider

The hole pattern inside the cabinet carcass acts as the backbone of the furniture construction, dictating the exact position for every fitting. To ensure that new hardware components work as alternatives to factory-fitted elements, three technical measurements must be verified.

System 32 and the Hole Grid

Most European furniture manufacturers use System 32. This means the vertical distance between the pre-drilled holes in the side panel is exactly 32 mm. The first line of holes is standardised at 37 mm from the front edge of the carcass. If the new runners support this hole pattern, they can be fixed using Euro screws (Ø 5 mm) without requiring additional drilling.

Internal Cabinet Width

The internal width is the clear interior dimension of the cabinet. It is calculated by taking the external width and subtracting the thickness of both side panels (typically 16 mm or 19 mm). For a 600 mm wide unit with 16 mm thick side panels, the internal width is exactly 568 mm. Modern drawer systems require precisely defined installation spaces to operate without play.

Nominal Length of the Drawer Runners

The depth of the cabinet determines the maximum length of the runner. The nominal length of the runners is generally specified in 50 mm increments, often starting at 250 mm up to 600 mm or more for kitchen applications. A clearance tolerance of at least 3 mm to 5 mm must be maintained between the back panel of the cabinet and the end of the runner.

Suitable Components for Retrofitting

Depending on the requirements for load capacity and extension type, different technical concepts are available. The choice of drawer runners significantly influences daily operating convenience in the kitchen.

Full Extension vs Single Extension

A single extension runner pulls out to approximately 75% of the cabinet depth. The rear section of the drawer remains inside the carcass, making access to items stored at the back more difficult. In contrast, a full extension runner provides a 100% extension path. The drawer pulls out completely past the front edge of the cabinet. For kitchen base units, full extension drawer runners are the technical standard, as they make every corner of the storage space fully accessible.

Runner Types and Mechanics

Basic roller runners operate using plastic wheels and are often found in older or budget furniture. A ball bearing runner uses steel ball bearings within a telescopic profile, providing smoother travel and higher load capacities. The undermount runner is fitted invisibly beneath the drawer base and provides the highest lateral stability.

To upgrade to modern closing comfort, fitters use drawer runners with soft-close mechanisms. These brake the momentum of the drawer front and pull the drawer shut softly and quietly over the final centimetres. If handleless fronts are desired, push to open drawer runners are required. A light push against the front triggers a mechanical spring that pops the drawer open. Soft-close and push-to-open are opposing mechanical systems and cannot be combined in purely mechanical designs.

Heavy-Duty Requirements and Safety

When storing pots, pans, or heavy stacks of plates, standard runners (often rated for 25 kg to 30 kg) reach their operational limits. In these cases, the use of heavy-duty drawer runners is essential, capable of supporting dynamic loads of 45 kg, 60 kg, or more without twisting.

For cabinets containing potentially hazardous items such as sharp knives or cleaning chemicals, integrating a drawer lock can also be practical to physically restrict access.

Installation and Retrofitting Steps

Fitting requires precision work to ensure the gap spacing around the drawer fronts remains consistent.

Required tools:

• Cordless screwdriver with PZ2 (Pozidriv) bit for chipboard screws or Euro screws
• Folding rule (tape measure) and pencil
• Bradawl (for marking any new pilot holes)
• Spirit level

Installation in 4 steps:

1. Fit the cabinet runners: Remove the old runners. Inspect the hole pattern in the carcass. Fix the new carcass runners at right angles to the side panels. When using the 32 mm grid, the runners are usually screwed into the frontmost hole (37 mm from the front edge).
2. Assemble the drawer box: For complete metal drawer side systems, screw the back panel and the base panel (usually 16 mm thick chipboard) to the metal sides.
3. Insert and engage: Place the assembled drawer onto the extended undermount runners and slide it in until the locking catches audibly click into place.
4. Align the front: Modern systems feature 3D adjustment (height, side, and tilt). Adjustment screws located behind the cover caps on the drawer sides allow precise alignment of the front gaps with surrounding cabinets (tolerance adjustment typically +/- 2 mm).

Additional Fittings for Kitchen Base Units

Once the mechanical hardware is renewed, interior accessories can be addressed. A smooth melamine base offers little grip for pots and glassware. An anti-slip drawer mat prevents items from sliding around during dynamic opening and closing, while protecting the drawer base from scratches and moisture.

For cutlery and cooking utensils, a made-to-measure kitchen drawer organiser provides structured compartments. In addition to drawers, waste separation systems are essential in base units. To make the best use of space under the sink, runner mechanisms can be used to install kitchen waste separation bins. These systems mount directly onto the carcass base or side panels and slide forward when opening the cabinet door.

Frequently Asked Questions (FAQ)

Can I replace an old roller runner with a modern undermount runner? Yes, this is technically feasible. The prerequisite is that the internal cabinet width and cabinet depth are sufficient. With undermount runners, the drawer base and back panel often require specific routings or specific dimensions. It is usually more efficient to replace the old wooden drawer box entirely with a new drawer side system.

How do I measure the required drawer runner length correctly? Measure the nominal length. This corresponds to the depth of the drawer box (excluding the front panel) from the back edge to the inner edge of the front. The runner length matches this dimension. The internal cabinet carcass must be at least 3 mm to 5 mm deeper than the nominal runner length.

Why does my newly installed soft-close drawer not shut completely? This is usually caused by an installation misalignment. Either the carcass is not completely square and level, or the internal clearance width of the drawer is too large or too small for the cabinet, creating tension along the runners. Check the diagonal measurements of the carcass and verify that the runners are screwed strictly parallel to each other.
