Soft-Close Drawer Runners as Replacements for Pelipal Kitchens

A soft-close system mechanically cushions the closing action and silently pulls the drawer shut over the final few centimetres, whereas conventional runners slam unchecked against the carcass.

When runners jam, stick, or lose their dampening on existing furniture, replacing the fittings is the right course of action. This frequently affects heavily used bathroom or kitchen units. Anyone looking for replacement parts suitable for Pelipal or similar established furniture systems must pay close attention to exact technical specifications when changing slides. A replacement is straightforward provided that fundamental parameters such as installation length, load capacity, and the drilling pattern match. This guide is aimed at fitters and joiners who wish to replace defective drawer runners with compatible components or retrofit older furniture with modern soft-close mechanisms.

What to Look for Regarding Compatibility

The successful replacement of a drawer runner requires an accurate analysis of the existing system. Fittings in mass-manufactured furniture are generally based on standardised grid dimensions.

System 32 and the Drilling Pattern

Most modern carcass systems use System 32. This means that the drill holes in the side panels have a vertical spacing of exactly 32 mm between each other. The distance from the frontmost hole to the front edge of the carcass is standard at 37 mm. When installing replacement parts suitable for Pelipal, you can generally use the existing hole rows in the carcass directly for the new runners, provided they are also designed for System 32.

Identifying Runner Types

Before installing new runners, the existing type must be identified:

• Roller runner: A simple system with plastic rollers. It typically requires 12.5 mm of space on each side.
• Ball bearing runner: Consists of interlocking metal profiles with steel ball bearings. It is screwed to the side or into a groove on the drawer box.
• Undermount runner: The runner sits invisibly beneath the drawer base. This is today's standard in high-quality bathroom and kitchen furniture.

Nominal Length and Extension Type

The length of the runner is referred to as the nominal length. Common dimensions range from 250 mm - 800 mm. The nominal length of the new runner must match the depth of the drawer, but it must not exceed the internal depth of the carcass.

In addition, a distinction is made between two extension types:

• A full extension runner can be pulled 100% out of the carcass. This allows unrestricted access right into the rearmost corner of the drawer.
• A single extension runner only opens the drawer to roughly 75%. The rear section remains inside the carcass.

Upgrading from a single extension to a full extension runner is usually straightforward within the same space requirements and significantly increases ease of use.

Suitable Components for Replacement

For repairing or upgrading existing carcass systems, the market offers a variety of compatible solutions. The choice of runner depends on the existing drawer box and the desired level of convenience.

Those wishing to equip classic wooden drawers with modern dampening opt for drawer runners with soft close. These side-mounted telescopic runners integrate a compact oil damper and a tension spring. Over the final centimetres of the closing stroke, the damper absorbs the kinetic energy, while the spring smoothly pulls the drawer into its final position.

For maximum access to storage space, drawer runners full extension are technically the best choice. Especially in the kitchen, where heavy pots or provisions are stored, unrestricted accessibility is essential. When planning complete cabinet conversions, it is worth looking at specific kitchen cabinet pull-outs. Here, the width of the carcass must be strictly taken into account. For instance, a kitchen cabinet pull-out 60 cm requires different base dimensions than narrower variants.

If the furniture came with concealed runners from the factory, undermount drawer runners must be used as replacements. These engage with special locking clips on the underside of the drawer. In this setup, the dampening system works like a miniature shock absorber on a car: it absorbs the kinetic energy of the loaded drawer and ensures silent closing, even when loaded with 30 kg.

Installation and Retrofitting: Step by Step

Replacing a runner requires precision, but it can be carried out efficiently with the right tools.

Required Tools

• Cordless screwdriver with suitable bits (usually PZ or TX)
• Folding rule or tape measure
• Spirit level
• Bradawl
• Chipboard screws (typically 3.5 x 16 mm or 4 x 16 mm countersunk)

Dismantling and Preparation

1. Remove the drawer. For undermount systems, this is usually done by releasing the locking clips on the underside; for ball bearing runners, by depressing small levers on the tracks.
2. Unscrew the old carcass runners.
3. Check whether the existing drill holes in the carcass (37 mm setback from the front edge, 32 mm grid) can be reused. If the wood around the drill holes is damaged, plug them with wooden dowels or mount the new runner shifted by one grid spacing up or down.

Fitting the New Runners

1. Mount the carcass runner: Position the new runner against the inner carcass wall. The frontmost screw is placed at the 37 mm mark. Check the horizontal alignment using a spirit level and drive in the remaining screws.
2. Mount the drawer runner: For side-mounted ball bearing runners, unlatch the inner member and screw it exactly in the centre or along the bottom edge of the drawer side. For undermount runners, fix the locking clips flush at the front underneath the drawer base.
3. Insert and engage: Place the drawer onto the carcass runners and push it in until the mechanism audibly clicks into place.
4. Fine adjustment: High-quality undermount systems feature adjustment wheels on the locking clips, allowing height (typically +/- 2 mm) and often side tilt adjustments of the drawer front. This ensures an accurate gap pattern.

Concealed Hinges as a Complementary Upgrade

When the drawers of a bathroom or kitchen cabinet are retrofitted with soft-closing runners, the loud slamming of cabinet doors above them often stands out negatively. A comprehensive upgrade therefore includes the door hinges as well.

Replacements for defective or unbuffered door hinges are provided by concealed hinges / cabinet hinges with soft close. Fixed standards apply here too: the diameter of the hinge cup hole in the door is almost always 35 mm. The door overlay type is crucial for compatibility. If the door fully overlays the carcass sides, a full overlay hinge is required. If the door sits flush inside the carcass sides, an inset hinge is necessary.

For standard kitchen cabinet doors, concealed hinges / cabinet hinges 110 degrees are ideal. This opening angle provides ample room to manoeuvre in everyday use without the door striking neighbouring fronts.

Frequently Asked Questions (FAQ)

Can I retrofit any old drawer with a soft-close runner? Technically yes, provided there is sufficient lateral clearance between the drawer and the carcass side panel. For ball bearing runners, this is usually 12.7 mm per side. For undermount runners, the drawer box requires specific rear cut-outs and a recessed base of at least 12 mm to 15 mm underneath.

Is soft-close the same as push-to-open? No, they are opposing mechanisms. Soft-close brakes the drawer as it closes and pulls it gently shut. Push-to-open (or tip-on) pushes the drawer slightly out of the carcass in response to mechanical pressure on the handleless front. Combining both systems is only possible with specialised, high-end fittings.

How do I determine the correct length for the replacement runner? Measure the depth of the drawer box (outer edge of the back panel to the inner edge of the front panel). The nominal length of the new runner should match this measurement or be slightly shorter. Also measure the internal depth of the carcass; the runner must not exceed this space, otherwise the drawer front will not close flush.

Why does the new runner feel stiff over the final few centimetres of opening? This is due to the integrated spring of the dampening system, which is tensioned during opening. Slight resistance during the first few centimetres of pulling open is normal and inherent to the design of mechanical dampening systems. When closing, the system utilises this stored spring tension to gently pull the drawer closed.
