Soft-Close Dampers as Replacements for Alno Kitchens

A soft-close mechanism gently decelerates furniture doors and drawers, silently pulling them into their closed final position over the last few centimetres.

Kitchen cabinets are subjected to high daily demands. After years of use, mechanical components such as hinges, drawer runners, or flap stays experience wear. When a door slams shut loudly or a drawer jams, replacing the entire furniture unit is usually unnecessary. By carrying out a targeted replacement of the fittings, functionality can be fully restored. This guide explains the technical parameters required to identify and correctly install accurate replacement dampers and hinges for Alno kitchens.

Compatibility: Technical Requirements for Replacement

The furniture industry has operated with standardised dimensions for decades. This considerably simplifies the search for replacement parts. Anyone seeking components compatible with Alno must, above all, measure the hole pattern and drillings of the cabinet carcasses and fronts.

The foundation of most kitchen units is System 32. This means the row hole drillings inside the cabinet have a continuous spacing of exactly 32 mm from one another. The distance from the front edge of the carcass to the centre of the first hole is also standardised at 37 mm. Fittings manufactured according to this grid fit existing drillings without issue.

For doors, the classic concealed cup hinge is used. The standard diameter for the drilling in the door (the cup) is 35 mm. Less common, smaller variants measure 26 mm. Alongside the diameter, the mounting type is crucial for the correct operation of the door:

• Full overlay: The door completely covers the carcass side when the cabinet is closed.
• Half overlay: Two doors share a single carcass side (centre partition). The door covers only half the edge.
• Inset: The door sits flush within the carcass sides.

If the wrong mounting type is selected during replacement, the cabinet door will not close properly.

Suitable Alternatives for Faulty Door Hinges and Dampers

When old hinges squeak or become worn, replacement is unavoidable. Standard opening angles for normal kitchen cupboards are 95° or 110°. For corner cabinets with carousels or internal drawers, wide-angle hinges with 155° or 165° are often required.

Those wishing to upgrade functional but noisy doors do not necessarily have to replace the entire hinge. As an alternative to original Alno components, separate door dampers can often be retrofitted. These are either clipped onto the existing hinge (provided they share an identical construction) or drilled or screwed into the carcass side as an independent component. Simple silicone buffers and dampers adhered to the front edge also reduce impact, though they do not provide an active self-closing action.

If the mechanism needs a complete renewal, one can opt directly for concealed hinges with integrated soft-close damping. In these models, the damping cylinder is integrated invisibly within the hinge arm or cup. For cabinets where damping is not required, classic concealed cabinet hinges with a standard closing spring are sufficient.

Drawer Runners: Replacing Worn Slides

Kitchen drawers often carry heavy loads of pots, pans, or crockery. When the runners stick or the damping fails, replacing the slides is necessary. Accurate replacement fittings are also available for Alno drawers.

First, the installation length must be determined. This typically ranges from 250 mm to 800 mm. Measure the depth of the drawer box from the back panel to the inside edge of the front.

Furthermore, a distinction is made between two extension types:

• A full extension runner pulls out 100% from the carcass. The entire contents are instantly accessible.
• A single extension runner opens only to approximately 75%. The rear section of the drawer remains inside the unit.

Modern convenience is provided by drawer runners with soft-close damping. They absorb the momentum of the drawer and pull it gently shut. When repairing heavy pan drawers, you should rely on full extension drawer runners with a high load capacity (e.g. 30 kg or 45 kg). Pay attention to the runner mechanism: while older kitchens often rely on side-mounted roller runners, modern units are usually equipped with concealed undermount slides beneath the drawer base.

Re-adjusting Kitchen Flap Cabinets

Wall units with upward-opening fronts use a gas strut (also known as a gas spring or gas damper) to assist movement. This holds the flap open and prevents it from falling uncontrolled. If the cylinder loses its internal pressure over the years, it must be replaced.

The force of a gas strut is specified in Newtons (N). Typical values range between 50 N and 150 N. The required force depends precisely on the weight and height of the furniture front. A damper that is too weak will not hold the flap open, while a damper that is too strong will cause the door to shoot upwards and make closing difficult.

For wall cabinets compatible with Alno, standard gas struts are suitable for lightweight fronts made of engineered wood or glass. For wide, solid fronts (such as microwave lift flaps), heavy-duty gas struts with higher Newton ratings are necessary.

Tools and Installation: Professional Replacement

Replacing fittings is like adjusting the tracking on a car — the mechanism only functions smoothly when accurately aligned. To replace hinges and runners, you will need the following tools:

• Cordless screwdriver or matching cross-head screwdriver (PZ for Pozidriv or PH for Phillips — check the drive type of the wood screws precisely to avoid stripping the heads)
• Folding rule or vernier calliper (to determine the cup diameter in mm)
• Pencil and bradawl (for marking and piloting new screw holes)

Step-by-step concealed hinge replacement:

1. Release the old door by pressing the release catch on the hinge arm (for clip-on models) or by loosening the fixing screw on the cruciform mounting plate.
2. Unscrew the old hinge from the 35 mm cup hole in the door.
3. Insert the new soft-close hinge into the drilling. Ensure it sits at an exact 90° angle to the door edge, then screw it into place.
4. Replace the mounting plate inside the cabinet carcass if the new hinge does not fit the old plate (observe the 32 mm hole spacing).
5. Clip the door into position and adjust the door alignment using the adjustment screws (height, depth, and lateral overlay).

FAQ – Frequently Asked Questions About Kitchen Spare Parts

Can I use any hinge as a replacement in my kitchen? No. The hinge must meet three criteria to ensure compatibility: the cup diameter must match the drilling in the door (usually 35 mm), the mounting type (full overlay, half overlay, or inset) must be identical, and the mounting plate must fit the 32 mm hole pattern of the carcass.

What is the difference between push-to-open and soft-close? These two systems serve opposite mechanical purposes. Push-to-open (or tip-on) is used for handleless fronts; pressing the door pops it open. Soft-close, by contrast, decelerates a moving door and pulls it shut. Combining both mechanisms in a single hinge requires specialised, complex fittings.

How do I calculate the required force for a new gas strut? The force in Newtons (N) is usually printed on the cylinder of the old damper (e.g. "80 N"). If the print is illegible, weigh the cabinet flap. As a rule of thumb, 10 N corresponds to a lifting capacity of approximately 1 kg. For a flap weighing 3 kg with struts fitted on both sides, you will require two struts of around 40 N to 50 N each.

Can roller runners be replaced directly with undermount slides? A direct 1:1 replacement is often difficult. Undermount slides require specific clearances beneath the drawer bottom and precise routing on the rear panel. When replacing worn side-mounted roller runners, the best option is usually a side-mounted ball bearing runner of identical installation length and height.
