Installing a Full-Extension Pull-Out Laundry Basket: Securing Wire Baskets via Ball-Bearing Runners in the 32 mm Hole Pattern

November 24, 2025

A full-extension pull-out laundry basket provides 100-percent access to the wire basket and is mounted via ball-bearing runners in the standardised System 32 of the cabinet carcass.

Retrofitting a wire basket system into a wardrobe or utility cupboard requires precise work and an understanding of the existing hole patterns in the unit. While basic roller runners often allow only partial access, a genuine full extension ensures that the basket can be pulled completely clear of the cabinet front edge. This makes removing laundry or items significantly easier.

This guide is aimed at fitters and ambitious DIY enthusiasts. It covers the technical installation of a ball-bearing runner on a side wire basket support system, the correct use of the hole pattern, and how to avoid typical collisions with hinges.

Key installation details:

Difficulty level: Medium
Time required: Approx. 30 to 45 minutes per pull-out
Required knowledge: Basic understanding of furniture hardware and grid dimensions

Required Tools and Materials

For the professional installation of the pull-out laundry basket, you do not need specialist machinery, but precisely matching hand tools to prevent damage to the screw heads and the carcass material.

Tools:

Cordless screwdriver with torque control
Screwdriver bit PZ2 (Pozidriv) for standard chipboard and Euro screws
Tape measure or folding rule
Pencil and try square
Bradawl or wood drill bit if required (Ø 5 mm for Euro screws, Ø 3 mm for pre-drilling chipboard screws)

Materials:

Wire basket / laundry basket including model-specific brackets (spacers)
A pair of full extension drawer runners (matching the basket and carcass depth)
Euro screws (6.3 x 13 mm) for an existing 5 mm hole line
Alternatively: Chipboard screws (countersunk head, 3.5 x 15 mm or 4 x 15 mm) if no pre-drilled holes exist

Preparation: Understanding System 32 and Depth Planning

Before using the cordless screwdriver, the position of the runners must be determined. Industrially manufactured cabinets generally feature System 32. This hole pattern serves as the cabinet maker's coordinate system: the distance from hole centre to hole centre is exactly 32 mm. The distance from the front line of holes to the front edge of the carcass is standard at 37 mm. The diameter of these drill holes is usually 5 mm, which is designed precisely for Euro screws.

The length of the runner depends on the internal carcass depth. If the cabinet is 50 cm deep, for example, a usable internal depth of around 480 mm usually remains after deducting the back panel. Here, 450 mm drawer runners are ideally used. For more compact furniture, shorter variants such as 400 mm drawer runners should be chosen accordingly. It is vital that the runner does not strike the back panel when fully closed and that the basket is not obstructed when closing the door.

Step-by-Step Guide: Installing a Pull-Out Laundry Basket

Installation is divided into fixing the runners to the cabinet carcass and connecting the wire basket to the runners. Proceed systematically to prevent the mechanism from jamming.

Step 1: Separate the Runner Profiles

Modern ball-bearing telescopic runners consist of several profiles running inside one another. To install the runner, you must separate the carcass profile (the outer, wide runner) from the drawer profile (the inner, narrow runner). Extend the runner completely. Inside, you will see a small plastic release lever (usually black). Press this lever up or down (depending on the side) and simultaneously pull the inner profile completely out towards the front.

Step 2: Mark the Installation Height

Determine the desired height of the laundry basket. Ensure there is enough clearance above to drop laundry inside. Mark the corresponding row of holes in the System 32 grid on the left and right inside of the cabinet. Use spacers if the cabinet features door hinges that project inwards. The basket must be able to glide past the open doors when extended.

Step 3: Screw on the Carcass Profile

Place the wide carcass profile against the marked row of holes. Position the frontmost fixing hole of the runner over the drill hole located 37 mm from the front edge. Secure the runner with Euro screws. Use at least three screws per runner (front, centre, rear) to absorb the tensile forces when pulling out a full laundry basket. Drive the screws in at an exact 90-degree angle so that the heads sit flush within the metal profile and do not catch on the ball bearings later. Repeat the process on the opposite side at the exact same height.

Step 4: Attach the Drawer Profile to the Wire Basket

Fixing the narrow inner runners to the wire basket varies depending on the basket model. Often, specific plastic clips or metal brackets are supplied with the basket, which hook into the wire and are then screwed to the drawer profile. Ensure that the profiles are aligned precisely parallel to one another. The closed end of the profile must face towards the cabinet back panel, and the open end (with the plastic entry guide) must face forwards.

Step 5: Insert and Engage the Basket

Bring the wire basket with the mounted drawer profiles up to the cabinet. Pull the ball cages in the carcass profiles all the way forward. Now feed the runners of the basket simultaneously into the carcass profiles on both the left and right sides. Push the basket backwards with light, even pressure. You will feel slight resistance as the release lever engages. An audible click confirms that the profiles are securely connected.

Step 6: Functional Check and Adjustment

Pull the laundry basket out fully several times and push it back in. The movement must be smooth and free from metallic scraping. If the pull-out catches, the runners inside the cabinet may not be mounted exactly parallel, or the wire basket may be under tension. In this case, check the width of the basket relative to the internal cabinet width and adjust the spacers if necessary.

Common Installation Errors and How to Avoid Them

Even with careful planning, errors can occur when installing runner systems. The following issues arise most frequently in practice.

Collision with the Concealed Hinge

A classic planning error is ignoring the door hinges. A concealed cup hinge takes up space inside the cabinet. If the laundry pull-out is installed at the exact height of a hinge, it cannot be pulled out. Furthermore, the opening angle of the door must be taken into account. A standard hinge with a full overlay often opens only to 95° or 110°. The door still protrudes slightly into the clear opening of the cabinet. The wire basket would scrape against the door front when pulled out. This can be resolved by using special spacer strips behind the runners to set the basket further inwards, or by replacing the hinges with wide-angle hinges (e.g. 155°), which swing the door completely clear of the internal opening.

Selecting the Wrong Type of Runner

For a wire basket loaded with heavy, damp laundry, a basic roller runner is often inadequate. Roller drawer runners are usually designed as single-extension runners and offer lower lateral stability. When the basket is pulled out far, it tends to tip. A ball-bearing telescopic runner provides the necessary rigidity.

Confusing Soft-Close and Opening Mechanisms

Terms are frequently confused when selecting hardware. A soft-close mechanism ensures that the basket is gently braked over the final centimetres and retracted quietly. This protects the material. Soft-close drawer runners are highly recommended for laundry baskets. In contrast, there are systems with push-to-open (tip-on). Here, the drawer springs open when pressure is applied to the front. Since an internal wire basket inside a cabinet does not have its own front panel to press against, this mechanism is technically unsuitable for internal laundry pull-outs and leads to malfunctions.

FAQ: Frequently Asked Questions About Pull-Out Laundry Baskets

What load capacity should a runner have for a laundry basket? For standard domestic laundry baskets, a typical load capacity of 30 kg to 35 kg is entirely sufficient. A basket full of clothes rarely exceeds this weight. However, if you repurpose the basket to store heavy tools or catalogues, you should opt for heavy-duty drawer runners with a load capacity of 45 kg or more.

Can I replace a single-extension runner with a full-extension runner? Yes, this is generally straightforward provided the System 32 hole pattern is present. You only need to remove the old runners and fit the new full-extension runners in the same position. Ensure that the installation width (the thickness of the runner, usually 12.7 mm) is identical so that the basket still fits between them.

Do these pull-outs also fit into kitchen base units? The mechanics are identical. If you are planning a wire basket for tea towels in the kitchen, the runners correspond to the carcass width. For a standard base unit, you will need the matching basket width, suitable for a 60 cm kitchen unit pull-out or narrower, such as a 50 cm kitchen unit pull-out. The installation of the side runners is carried out exactly as described for the wardrobe.

Why do undermount runners not work with wire baskets? Undermount drawer runners are, as the name suggests, fitted beneath the base of a wooden drawer box and engage with specific drill holes on the rear of the drawer. A wire basket has neither a wooden base nor a solid panel back into which the locking clips of an undermount runner could lock. Therefore, side-mounted telescopic runners are strictly required for wire baskets.
