Replacement Parts & Compatible Fittings for Alno — Overview

Compatible replacement parts for Alno kitchens generally follow the standardised System 32, allowing defective hinges, runners, and flap stays to be replaced with dimensionally identical alternatives.

The maintenance and repair of kitchen units requires precise mechanical components. When hinges give way, drawers stick, or lift-up doors no longer stay open, replacing the fittings becomes necessary. When searching for replacements for Alno kitchens, it is not strictly necessary to rely on manufacturer-specific original parts. Crucial to ensuring a precise fit is matching the technical parameters, particularly the hole patterns, routings, and load capacities. This guide is aimed at fitters and joiners, explaining the technical criteria for compatible fittings.

What to Look for Regarding Replacement Part Compatibility

Cabinet construction across Europe relies heavily on industrial standards. The most important design principle here is System 32. This grid dimension defines the spacing between drill holes in cabinet side panels, which is exactly 32 mm. The distance from the front row of holes to the front edge of the cabinet is standard at 37 mm.

When looking for fittings suitable for Alno, check this hole pattern first. If the spacings of the mounting plates and runners match this grid, alternative components can be installed without additional drilling work. Replacing a hinge is like changing a wheel on a vehicle – if the bolt circle and dimensions match exactly, the replacement part integrates smoothly into the existing mechanism.

Suitable Replacement Parts and Compatible Fittings for Alno

Selecting the correct mechanism requires precise measurement of the old components in millimetres as well as determining the exact operating type.

Concealed Cup Hinges and Fittings

Concealed hinges, commonly known as cup hinges, are the most frequent wear parts. Two dimensions are critical for compatibility: the diameter of the cup hole in the door and the opening angle. In most kitchen frontals, the cup diameter is exactly 35 mm.

Additionally, the mounting overlay type must be determined:

• Full overlay: The door completely covers the cabinet side panel.
• Half overlay: Two doors share a central cabinet partition wall.
• Inset: The door sits entirely flush inside the cabinet frame.

An alternative to Alno hinges must feature the exact same overlay type. When retrofitting, you can also choose between models with integrated soft-close damping or un-sprung/standard variants.

Drawer Runners and Extension Systems

When replacing guide runners, the nominal length (frequently 450 mm or 500 mm in kitchen applications) and the installation width must be taken into account. A distinction is made between two opening types: a full extension runner pulls out 100% from the cabinet carcass, whilst a partial extension stops at approximately 75%.

The mechanism itself is usually based on ball-bearing runners (side-mounted telescopic slides) or an undermount runner (fitted concealed beneath the drawer base). For heavy-duty drawers, pay attention to the specified load capacity in kilograms, as pots and crockery generate high dynamic loads.

Flap Mechanisms and Wall Units

Wall units are frequently equipped with upward-opening front panels. This is where flap stays and lift-up fittings are used. If the front panel no longer remains in the open position, the gas strut is usually defective.

When looking for a replacement for Alno gas struts, the force rating in Newtons (N) is the critical factor. This is usually printed directly on the cylinder (e.g. 250 N, 320 N, or 380 N). A strut that is too weak will not hold the flap open, whilst one that is too strong will prevent proper closing. For particularly large and heavy panels made of MDF or solid wood, specialised gas struts for heavy flaps with a correspondingly high stroke and rating must be installed.

Kitchen-Specific Fittings and Accessories

Alongside moving hardware, there are rigid connecting fittings. For seamless and secure jointing of worktops at corners, specialised worktop connectors are recessed into routed slots on the underside and tensioned with a threaded bolt.

To functionally upgrade wall units above the sink, a plate rack for wall cabinets can also be retrofitted. Such systems are likewise based on standard cabinet carcass widths (e.g. 600 mm or 800 mm) and are fixed via side brackets into the system grid.

Cross-Room Furniture Concepts

Because open-plan kitchens often transition smoothly into living areas, joiners use the same compatible fitting systems for adjacent furniture units. Using identical cup hinges and undermount runners, suitable hardware setups can be built for a TV sideboard or a low TV unit.

If part of the kitchen run is adapted into a work area, a recessed desk cable grommet ensures tidy routing of appliance cables. In bedroom spaces as well, such as when assembling fittings for a double wardrobe, fitters utilise the identical System 32, cam connectors, and hinge types that are standard in kitchen installation.

Installation and Retrofitting of Compatible Fittings

Installing compatible replacement parts requires technical understanding and the right tools.

Required tools:

• Cordless drill/driver
• Pozi screwdriver (PZ drive for chipboard screws, PH for sheet metal screws)
• Folding rule or vernier caliper
• Where applicable, a Forstner bit (35 mm) for new hinge cup holes

Steps for replacing a concealed hinge:

1. Measurement: Measure the cup diameter and the distance between fixing screws on the mounting plate.
2. Removal: Loosen the screws of the cruciform mounting plate on the carcass. With clip-on hinges, the door can be removed beforehand without tools by pressing the rear release button.
3. Installation: Insert the compatible hinge into the 35 mm hole of the door and screw it tight.
4. Adjustment: Attach the door to the carcass. Use the 3D adjustment screws on the hinge arm to set the gap height, depth, and lateral overlay precisely to between 1.5 mm and 2.0 mm.

Frequently Asked Questions (FAQ)

Can I use any random hinge as a replacement part? No. The replacement part must strictly share the same cup diameter (usually 35 mm) and the same overlay type (full overlay, half overlay, or inset). In addition, the hole pattern of the mounting plate must match the existing grid in the carcass.

How do I find the correct gas strut for my lift-up flap? Read the rating in Newtons off the old gas strut. This value (e.g. 250 N) must be identical on the new component. If the value differs, the flap will either close too hard or fail to stay open.

Are soft-close and push-to-open the same thing? No, these are opposing mechanisms. Soft-close is a damper that decelerates the closing movement of the door or drawer. Push-to-open (also known as tip-on) is an ejection mechanism for handleless fronts that opens the door when pressed. Both systems cannot usually be combined within the same fitting.

Which screws are suitable for mounting fittings? Use dedicated Euro screws for pre-drilled holes in the 5 mm grid. For direct fixings into chipboard, chipboard screws with a diameter of 3.5 mm to 4.0 mm are suitable. Ensure you use the correct drive type (PZ or TX) to avoid rounding the screw head.
