Soft-Close Drawer Runners as Replacements for Alno Kitchens

A soft-close runner dampens the momentum of a drawer and pulls it in gently and silently over the final centimetres, making it an ideal replacement for worn or defective mechanical runners.

When the runners of an older fitted kitchen jam, catch, or have broken plastic rollers after years of heavy use, a replacement is due. People often specifically search for brand-specific spare parts. Technically, however, it is generally not mandatory to use identical components from the original kitchen manufacturer. As long as the installation dimensions, hole pattern, and load capacity match, modern fittings can easily be used as replacements for Alno kitchens or models from other manufacturers.

This guide explains the technical specifications fitters and experienced DIYers must consider to find the right alternative to Alno fittings and bring drawers up to modern standards.

What to Look for Regarding Compatibility

Choosing the correct replacement part does not depend on a brand logo, but on exact millimetre measurements and the construction of the cabinet carcass. To select fittings suitable for Alno cabinets, the following parameters must be determined:

1. Nominal Length and Installation Depth

The length of the runner depends on the depth of the drawer. Standard lengths in furniture making range from 250 mm - 800 mm. For standard kitchen base units, runners with a nominal length of 450 mm or 500 mm are typically used. The cabinet carcass must have a clear internal minimum depth, which generally corresponds to the nominal length plus a 3 mm to 5 mm tolerance.

2. Extension Type: Full Extension vs. Partial Extension

A full extension allows the drawer to be pulled 100% out of the carcass. This provides full access right to the rearmost corner. A partial extension, on the other hand, stops at around 75% of the runner length, leaving the rear area inside the cabinet. When retrofitting, switching to drawer runners full extension is often recommended, provided the drawer construction allows it.

3. Runner Types

• Roller runners: The classic standard in older kitchens. An epoxy-coated metal runner runs over a plastic roller.
• Ball bearing runners: Telescopic runners mounted to the side of the drawer. They run on steel ball bearings and typically require a lateral side clearance of exactly 12.7 mm per side.
• Undermount runners: The runner is mounted concealed beneath the drawer base. This is the modern standard, as the hardware remains invisible. Undermount drawer runners, however, require specific routing or construction of the wooden drawer box.

4. System 32

Most industrially manufactured kitchen cabinets are based on System 32. This means that the rows of holes in the carcass feature a vertical spacing of exactly 32 mm, and the distance from the front edge of the cabinet to the first hole is 37 mm. If the replacement runner is also designed for this hole pattern, the existing drill holes in the cabinet can be reused directly.

Matching Replacement Parts for the Drawer System

When replacing kitchen cabinet pull-outs, the cabinet width also plays a role in sizing the load capacity. A heavily loaded pan drawer requires heavy-duty runners, whereas standard runners with a load capacity of around 30 kg are sufficient for a cutlery drawer.

Specific solutions compatible with Alno standard dimensions are available for different carcass widths:

• A kitchen cabinet pull-out 60 cm is the classic dimension for hob units or pots and pans.
• A kitchen cabinet pull-out 50 cm or a kitchen cabinet pull-out 40 cm is frequently used for food supplies and crockery.
• Narrow variants such as the kitchen cabinet pull-out 30 cm, the kitchen cabinet pull-out 20 cm, or the kitchen cabinet pull-out 15 cm are often found as larder units or spice pull-outs in alcoves.

Switching to drawer runners with soft close is possible across all these widths, as long as the lateral side clearance and depth have been measured correctly.

Replacing runners is much like balancing a tyre in a workshop – only when the geometry is accurate to the millimetre will the movement run smoothly and free of vibrations in the end.

Installation and Retrofitting of New Runners

Replacing mechanical runners with soft-close versions requires precise workmanship.

Required Tools

• Cordless screwdriver with suitable bits (PZ or TX)
• Tape measure or folding rule
• Spirit level
• Bradawl or a 3 mm wood drill bit
• Chipboard screws (usually Ø 3.5 mm or 4 mm)

Step-by-Step Installation

1. Dismantling: Remove the old drawer and unscrew the runners from the carcass. If dealing with roller runners, the profiles screwed to the drawer must also be removed.
2. Measuring and marking: Check whether the old hole pattern (typically System 32) can be used for the new runners. If not, mark the new horizontal line using a spirit level.
3. Mounting the carcass profile: Screw the new runners to the inner cabinet wall. Use Euro screws (for existing 5 mm holes) or traditional wood screws for this.
4. Mounting the drawer profile: Fasten the counterpart to the drawer. With an undermount runner, the locking devices are also screwed to the front underside of the drawer base.
5. Inserting and adjusting: Slide the drawer onto the runners until it audibly clicks into place. Using the adjustment screws on the clip or runner, you can now adjust the alignment in height and partly in tilt.

Upgrading Doors Too: Concealed Hinges with Soft-Close

Those renewing their kitchen runners often modernise their cabinet doors in the same step. Here, too, springs wear out over the years. A concealed hinge is the standard hinge in furniture construction. The cup hole in the door almost always features a diameter of 35 mm in kitchen cabinets.

If you are looking for hinges as an alternative to original Alno parts, you must determine the overlay type in addition to the cup diameter:

• Full overlay: The door rests completely over the carcass side edge.
• Half overlay: Two doors share a central carcass partition wall.
• Inset: The door sits flush inside the carcass frame.

For standard kitchen cabinets, an opening angle of 110° is usually required. Matching replacement parts can be found under concealed hinges / cabinet hinges 110 degrees. If you wish to make door closing just as silent as drawer closing, choose concealed hinges / cabinet hinges with soft close. In modern versions, the damping cylinder is integrated directly into the hinge arm.

FAQ – Frequently Asked Questions About Replacing Kitchen Runners

Can I combine soft-close damping with push-to-open? No, this is mechanically not possible with standard fittings. A soft-close mechanism slows the drawer down and pulls it shut. A push-to-open mechanism builds up tension during closing to eject the drawer again upon pressure. These are opposing mechanisms.

How do I measure the length of the required drawer runner correctly? Measure the length of the drawer on the outside from the rear panel to the inside of the front panel. Round this value down to the nearest smaller standard dimension (e.g. from 480 mm to 450 mm) if necessary. The runner must never be longer than the internal carcass depth.

Do I need to modify the drawer when replacing partial extensions with full extensions? For side-mounted ball bearing runners, a partial extension can usually be replaced 1:1 with a full extension, provided the installation width (usually 12.7 mm per side) is identical. For undermount runners, the position of the locking clips and the depth of the rear cut-out must match.

Which screws do I use for fixing into a chipboard carcass? Use dedicated countersunk chipboard screws, ideally with a PZ or TX drive for optimal torque transmission. The diameter should be 3.5 mm or 4 mm; the length depends on the carcass thickness (usually 16 mm or 18 mm), with 15 mm or 17 mm long screws typically being used.
