IKEA PAX Wardrobe Fittings: Compatible Hardware Guide

The IKEA PAX system is one of the most widely used modular storage solutions in UK homes. While these carcasses offer immense versatility, their hardware components—such as hinges, drawer slides, and shelf pins—frequently require replacement due to wear, or upgrading to achieve higher performance. Fortunately, because the carcass design adheres closely to standard European cabinetry conventions, finding compatible ikea pax wardrobe fittings across trade hardware ranges is straightforward once you understand key dimensions.

Understanding the 32mm Cabinet System

At the core of PAX modularity is the standard 32mm cabinet system. The pre-drilled vertical holes running down the inside of PAX carcasses feature 5mm diameter holes spaced exactly 32mm apart centre-to-centre, positioned 37mm back from the front edge. This layout is standard across the European furniture hardware industry, allowing you to use a wide variety of aftermarket fittings without needing to drill new holes.

• Hole Diameter: Standard 5mm drillings accept Euro screws, shelf supports, and mounting plates.
• Row Spacing: 32mm vertical increments allow for versatile positioning of runners and accessories.
• Front Setback: 37mm distance from the front edge to the first hole line aligns with standard hinge mounting plates.

Hinges: Upgrading and Replacements

PAX wardrobe doors standardly use concealed European-style cup hinges with a 35mm cup diameter drilled into the back of the door. If original hinges sag, snap, or lack dampening, standard 35mm clip-on hinges can serve as direct replacements.

Hinge Overlay and Opening Angles

Standard PAX layouts generally utilise full overlay hinges (typically 110° opening angle), where the door sits over the carcass edge. However, if your wardrobe includes internal drawers or pull-out wire baskets, standard 110° hinges can cause the door to obstruct the drawer path when opened. In these layouts, zero-protrusion hinges (often opening to 155° or 165°) are essential to swing the door completely clear of the internal frame.

Drawer Runners and Internal Pull-Outs

Upgrading the movement of internal timber drawers or retrofitting bespoke timber boxes inside a PAX unit is entirely possible using standard furniture fittings. When selecting replacement runners, key specifications must be matched:

• Length: Standard depth PAX units (58cm carcass depth) generally accommodate 500mm or 550mm drawer runners, while shallow depth frames (35cm carcass depth) typically suit 300mm runners. Always measure internal clearance before purchasing.
• Fixing Method: Use 5mm flat-head Euro screws (typically 11.5mm to 13mm in length) to secure the runner directly into the pre-drilled holes, ensuring a strong mechanical hold without splitting the chipboard core.
• Action: You can choose between ball-bearing side-mounted runners or concealed undermount soft-close slides depending on the design of your drawer boxes.

Handles, Knobs, and Alignment Fixings

Changing door handles is the simplest aesthetic upgrade. Most PAX doors are supplied without pre-drilled handle holes, meaning any standard single-hole knob or multi-hole handle with 96mm, 128mm, or 160mm hole centres can be fitted using standard M4 machine screws.

For stability, multiple PAX units placed side by side should always be connected. Standard cabinet connecting bolts (sleeve connectors) fitting 5mm or 8mm holes provide far greater rigidity than simply screwing carcasses together with wood screws.

Frequently Asked Questions

Can I fit standard soft-close hinges to older PAX doors?

Yes. As long as the door has standard 35mm hinge cup drillings with standard depth, standard European soft-close hinges and compatible 37mm setback mounting plates will fit.

What screws should I use in the pre-drilled PAX holes?

Always use 5mm diameter Euro screws (Varianta screws) for mounting runners and hinge plates into the pre-drilled carcass holes, rather than standard pointed wood screws which can strip the particleboard.
