Soft-Close Runners Compatible with Nobilia Kitchens

A soft-close runner hydraulically cushions the closing movement of a drawer over the final few centimetres and pulls it shut automatically and silently.

When the runners in an existing kitchen wear out after years of intensive use, catch, or lose their damping function, a complete kitchen replacement is rarely necessary. A targeted replacement of the fittings restores full functionality. However, anyone seeking replacement hardware compatible with Nobilia kitchens must pay attention to exact technical specifications, dimensions, and hole patterns to guarantee smooth operation. This guide is aimed at fitters and technically skilled users who want to replace defective drawer runners and hinges with compatible components.

What to Look for Regarding Compatibility

Kitchen manufacturers generally use standardised grid dimensions and drill holes for their carcasses. Replacing a drawer runner is much like changing a tyre on a car – the hole centres and installation dimensions must match precisely, otherwise the component cannot be mounted.

The most important dimension when installing furniture hardware is the System 32 standard. This industry-wide hole pattern defines the distance between drill holes (exactly 32 mm) as well as the distance from the frontmost hole to the front edge of the carcass (typically 37 mm). If you are looking for fittings as alternatives to original Nobilia parts, you should check whether the existing holes in the cabinet carcass match this grid.

Another decisive criterion is the type of runner:

• Undermount runner: The runner sits invisibly underneath the drawer base. This is the standard in modern kitchens.
• Ball-bearing runner: The runner is screwed to the side of the drawer. It remains visible when the drawer is opened.
• Roller runner: A basic system using plastic rollers, which is rarely installed in high-quality kitchens today.

Furthermore, an extension type must be distinguished. A full extension runner can be pulled out of the carcass by 100%, allowing full access to the entire contents. A single extension stops at approximately 75% of the depth. When replacing old runners, upgrading to full extension drawer runners is often recommended, provided the cabinet depth permits it.

Suitable Runners for Different Cabinet Widths

The nominal length of the runner (the depth extending into the cabinet) and the load capacity (in kilograms) must match the existing drawer box. Common nominal lengths in kitchen cabinets range between 400 mm and 550 mm. The width of the drawer, on the other hand, determines whether additional stabilisers are required.

When replacing kitchen cabinet pull-outs, use the external width of the carcass as a guide. furnica offers compatible solutions for all standard grid dimensions. For narrow base units, which are often used to store spices or tea towels, a 30 cm kitchen cabinet pull-out or a 40 cm kitchen cabinet pull-out is commonly used.

For wider base cabinets designed for pots and pans, the load capacity of the runner is crucial. A 60 cm kitchen cabinet pull-out strictly requires runners capable of handling a dynamic load of at least 30 kg, or ideally 40 kg to 50 kg, without sagging. When purchasing drawer runners with damping, ensure that the weight of the loaded drawer does not exceed the specifications of the soft-close unit, as otherwise the soft-close mechanism will no longer pull the drawer front shut reliably.

Hinges: Compatibility for Kitchen Fronts

Alongside drawers, the hinges on standard opening doors are among the most heavily stressed wear-and-tear parts. Here too, defective parts can be replaced with compatible components. The standard concealed cup hinge in kitchens requires a cup hole drilled into the door front with a diameter of exactly 35 mm.

When replacing hinges, you must identify the door overlay type:

• Full overlay: The door completely covers the side panels of the carcass when closed.
• Half overlay: Two doors share a single dividing side panel (twin application).
• Inset: The door sits flush inside the carcass side panels.

For standard kitchen cabinets, an opening angle of 110° is most commonly used. For this, 110-degree cup hinges / cabinet hinges are ideal. However, if the door needs to open wider around a corner or for internal pull-out drawers, wide-angle hinges with 155° or 165° opening angles are used. To prevent cabinet doors from slamming loudly, you can use damped cup hinges / cabinet hinges with soft close as replacements designed to fit the existing 35 mm drill holes.

Installation and Retrofitting: Step by Step

Replacing runners requires precision. A deviation of just a few millimetres will cause the fronts to scrape or result in uneven gap reveals.

Required Tools

• Cordless screwdriver
• Matching bits (usually PZ size 2 or TX size 20)
• Folding rule (tape measure)
• Pencil and square
• If necessary, an awl for marking and pre-punching new screw positions

Installing Drawer Runners

1. Removal: Remove the drawer. On modern undermount runners, release the locking catches on the underside of the drawer. Unscrew the old runners from inside the carcass.
2. Check the hole pattern: Hold the new carcass runner against the side panel. Use the frontmost drill hole according to System 32 (37 mm from the front edge).
3. Screw the carcass runner in place: Fasten the runner using Euro screws (for 5 mm drill holes) or chipboard screws (for 3 mm drill holes). Ensure the runner is positioned perfectly level.
4. Fit the locking catches: If you are using an undermount runner, screw the new locking catches flush to the front corners of the drawer base.
5. Insert and adjust: Place the drawer on the runners and push it in until the locking catches audibly click into place. Use the adjustment wheels on the catches to adjust the height and tilt of the drawer front until the kitchen alignment and gap reveals are completely uniform again.

Frequently Asked Questions (FAQ)

Can I use any soft-close runner as a replacement for Nobilia? No. The runner must match the existing drawer box (drawer side profile) precisely in both construction type (undermount vs. side-mount) and nominal length. The position of the locking catches also varies by manufacturer. When replacing runners designed to be compatible with Nobilia, check the depth of the wooden or metal drawer box in millimetres.

What is the difference between soft-close and push-to-open? These two mechanisms are often confused, but in their pure mechanical form they are mutually exclusive. Soft-close is a damping system that slows the drawer down when closing and pulls it gently shut. Push-to-open (or tip-on) is an opening mechanism for handleless fronts: pressing against the closed drawer activates a spring that pushes it open.

How do I measure the correct runner length? Do not measure the full depth of the entire kitchen cabinet; measure only the external depth of the drawer box (from the back of the front panel to the rear panel of the drawer). Typical measurements are 450 mm or 500 mm. The runner must match this nominal length exactly so that the locking mechanisms engage correctly.

Which screws should I use for fixing into the carcass? If your kitchen carcass features pre-drilled System 32 hole lines (Ø 5 mm), use dedicated Euro screws with flat, blunt ends. If you need to drill new pilot holes, use wood screws (chipboard screws) with a diameter of 3.5 mm or 4 mm. Always pay attention to the correct drive type – never use a PH bit for a PZ screw to avoid stripping the screw head.
