Soft-Close Drawer Runners Suitable for IKEA Faktum

A soft-close drawer runner dampens the momentum of a drawer over the final few centimetres and pulls it silently and flush into the cabinet carcass via an integrated spring mechanism.

The Faktum kitchen system from IKEA was the standard in many homes for years. Since the system was replaced by the Metod range in 2014, finding suitable replacement parts has become increasingly difficult. When old drawer runners are worn out, jamming, or slamming shut loudly, a complete kitchen replacement is not necessary. The carcasses are based on industrial standards, meaning modern fittings can easily be used as replacements for IKEA Faktum.

This guide is aimed at fitters and experienced DIYers looking to retrofit Faktum kitchen cabinets with modern dampening technology or replace defective runners.

Key Compatibility Considerations

For new drawer runners to be compatible with IKEA Faktum, several technical parameters must match the existing cabinet carcass and drawer box precisely. The older system used specific fittings for "Rationell" drawers, but these were built around the industry-standard drilling pattern.

System 32 and the Hole Pattern

The side panels of Faktum carcasses feature a continuous row of holes. This System 32 means that the distance between the centres of two drilled holes is exactly 32 mm. The distance from the front edge of the carcass to the first row of holes complies with standard specifications at 37 mm. The diameter of these system drillings is 5 mm.

When you fit compatible runners, the fixing points of the new hardware align precisely with this grid. Special Euro screws with a thread diameter of 6.3 mm are used for installation in these pre-drilled holes.

Installation Length and Nominal Length

A Faktum base cabinet typically has an external carcass depth of 600 mm, with a usable internal depth of just under 580 mm. The original drawers usually have a depth of 500 mm to 530 mm. The nominal length of the new runner must match the depth of the drawer box. A runner that is too long will hit the back panel, whilst one that is too short will not adequately support the drawer. For standard Faktum base cabinets, runners with a length of 500 mm are usually the correct choice.

Extension Type: Full Extension vs Single Extension

When selecting a replacement, the extension range is a key consideration. A single extension runner allows the drawer to be pulled out by only about 75%. The rear section of the drawer remains hidden inside the carcass, making access to items stored there difficult. A full extension runner, on the other hand, extends 100%. The drawer travels completely clear of the carcass front. Especially in the kitchen, where pots and food supplies must be easily accessible, this design represents the technical standard.

Suitable Components as an Alternative for Faktum Kitchens

To restore or enhance the functionality of the kitchen, the hardware range offers various technical solutions compatible with the Faktum system.

Ball-Bearing Runners with Soft-Close

For wooden drawers or bespoke pull-outs, side-mounted telescopic runners are frequently used. A ball-bearing slide consists of interlocking metal profiles separated by steel ball bearings. This design ensures a high load capacity of often 30 kg to 45 kg alongside smooth running. When opting for drawer runners with dampening, a small hydraulic damper absorbs the kinetic energy of the closing drawer—similar to a vehicle shock absorber.

To ensure maximum convenience when retrieving kitchen utensils, fitting drawer runners full extension is recommended. This makes the entire storage space right to the back corner fully accessible.

Concealed Runners for Wooden Drawers

A visually sleeker option involves fittings mounted underneath the drawer base rather than on the sides. These undermount drawer runners are invisible when the drawer is open. However, they require a specific wooden drawer construction: the side panels must extend downwards past the base to accommodate the runner. This variant is ideal for custom-built wooden drawer boxes integrated into a Faktum carcass.

Complete Drawer Box Kits

If not only the runner is defective, but the side panels of the old Rationell drawer are cracked or the front connectors are broken, replacing the entire box is worthwhile. Modern drawer systems consist of double-walled steel sides into which a back panel and base made of chipboard (usually 16 mm thick) are fitted. These systems come with the soft-close mechanism built into the runners from the factory and screw seamlessly into the Faktum cabinet via the 32 mm grid.

Installation and Retrofitting: Replacement in a Faktum Carcass

Retrofitting or replacing drawer runners requires precise work, but can be completed with standard hand tools.

Required Tools:

• Cordless drill/driver
• Screwdriver with PZ (Pozidriv) or TX (Torx) drive
• Tape measure or folding rule
• Spirit level

Step-by-Step Installation:

1. Removal: Remove the old drawer from the cabinet. On ball-bearing runners, a small release lever on the runner usually needs to be pressed to detach the drawer box.
2. Remove old runners: Unscrew the old runners from the carcass side walls.
3. Check positioning: Hold the new runner against the carcass wall. Align the mounting holes of the runner with the existing 5 mm System 32 drillings. Ensure that the runner is completely level.
4. Carcass mounting: Secure the runner using Euro screws (6.3 x 13 mm or 6.3 x 14 mm) in the pre-drilled holes. Use the appropriate PZ bit to prevent damaging the screw heads.
5. Drawer box mounting: Fit the mating member of the runner (for telescopic slides) onto the side of the drawer box. Standard wood screws (countersunk, 3.5 x 16 mm) are used for this.
6. Insertion and adjustment: Slide the drawer into the cabinet carcass until the runners click audibly into place. Test the movement and the soft-close dampening function.

Tip for uniform closing action: When upgrading drawers with soft-close, cabinet doors should also be prevented from slamming. Old hinges can be replaced with concealed cabinet hinges with soft-close. For standard kitchen doors, 110-degree concealed cabinet hinges with a cup diameter of 35 mm are the correct choice.

FAQ – Frequently Asked Questions About Compatibility

Can I combine soft-close with push-to-open? No, these two mechanisms work in opposite ways. A soft-close system decelerates the drawer and pulls it closed. A push-to-open (tip-on) system requires closing pressure to tension a spring that pushes the drawer open the next time it is pressed. If you are planning handleless fronts, you must use push to open drawer runners without dampening.

How do I correctly measure the required length for my Faktum drawer? Measure the depth of the existing drawer box (outer edge to outer edge) in millimetres. The dimension of the box determines the nominal length of the runner. For a box depth of 500 mm, order a runner with a nominal length of 500 mm. Do not measure the old runner in its extended state.

Why is the new soft-close drawer stiff to pull during the initial few centimetres? This is normal mechanical behaviour. When opening the drawer, the spring mechanism of the damper must be tensioned. This slight resistance over the initial centimetres of extension stores the energy needed later to pull the drawer smoothly into the carcass over the final millimetres.

Do the holes on the new runners align exactly with the old drillings? Because Faktum uses the standardised 32 mm hole pattern, the height alignment of third-party runners matches the drillings precisely. However, depending on the design of the new runner, you may need to offset the runner forward or backward by one hole increment (32 mm) in depth.
