Soft-Close Dampers Compatible with IKEA Pax
A soft-close damper or a cushioned concealed cup hinge is compatible with the IKEA Pax system if it features the standardised hole pattern according to System 32 and a 35 mm cup diameter.
Retrofitting wardrobe doors and drawers with soft-closing mechanisms is one of the most common customisations in furniture making. When wardrobe doors slam shut loudly, the proper dampening mechanism is often missing. Upgrading works like an acoustic shock absorber for the wardrobe: the door is gently braked over the final few centimetres and closes silently. For fitters and experienced DIYers, replacing hinges or adding dampers is a straightforward routine task, provided that the technical specifications of the replacement hardware match the carcase precisely.
Technical Requirements for Compatibility with IKEA Pax
To choose replacement fittings or extensions compatible with the IKEA Pax system, standard furniture industry dimensions must be observed. The cabinet carcase of this wardrobe type is based on established industry standards, which simplifies the search for an alternative to factory-fitted hardware.
System 32 and the Hole Pattern
The side panels of the carcase feature continuous line drilling. These pre-drilled holes have a diameter of 5 mm and an exact spacing of 32 mm from one another. This System 32 defines where the cruciform mounting plate of the hinge or the runner rail of a drawer is screwed in. The distance from the front edge of the carcase to the first row of holes is standardly 37 mm. Compatible fittings must feature this exact hole pattern to be fitted without additional drilling.
Cup Diameter and Drilling Depth
The core of the door fixing is the concealed cup hinge. The circular recesses routed into the wardrobe doors have a diameter of 35 mm. The depth of the hole is generally between 11.5 mm and 12.5 mm. Replacement hinges must strictly be designed for a cup diameter of 35 mm. A smaller 26 mm hinge would not hold securely within the recess.
Type of Overlay and Opening Angle
On classic wardrobes, the door rests on the side panels of the carcase when closed. This is a full overlay (also known as a standard overlay). When ordering, this must not be confused with an inset application (door sits fully within the carcase) or a half overlay / dual mounting (for central panels where two doors are mounted back-to-back).
The standard opening angle for regular wardrobe doors is 110°. If you are searching for an exact replacement, concealed cabinet hinges 110 degrees are the technically correct choice. If the doors need to open wider, for instance in wardrobes with internal drawers, hinges with 155° or 165° are used.
Suitable Replacement Hardware for Retrofitting
Depending on your starting situation, there are various technical approaches to integrating dampening or replacing defective components.
Integrated Soft-Close Hinges
The neatest solution is replacing the old hinges entirely with concealed cabinet hinges with soft close. In these models, the hydraulic damping cylinder is integrated directly within the hinge arm. They are fully compatible with the 35 mm door drillings and the 32 mm carcase hole pattern. Those who prefer to forgo soft-close can opt for standard concealed cabinet hinges with a conventional sprung self-closing mechanism.
Clip-On Dampers and Buffer Pads
If the existing hinges are fully intact, external door dampers can be retrofitted. These components are either clipped directly onto the hinge arm of compatible hinges or screwed into the carcase as an independent fitting. Alternatively, simple silicone door buffers from the buffers and dampers range soften the hard impact of wood on wood, although they do not provide a mechanical braking action.
Drawer Runners
Internal drawer units can also be upgraded. When replacing or constructing drawers compatible with IKEA Pax, you will need runners that screw directly into the System 32 hole line. Drawer runners with soft close absorb the drawer's momentum and pull it quietly closed over the final millimetres. Take note of the extension type: a full-extension runner pulls out 100% from the carcase, making access to garments stored at the back considerably easier. Corresponding full-extension drawer runners are available for furniture making in lengths ranging from 250 mm - 800 mm.
Guide: Installing Soft-Close Hinges on a Wardrobe
Replacing hinges on an existing carcase requires precise working, but it can be completed quickly with the correct tools.
Required Tools
- Cordless screwdriver or hand screwdriver with PZ (Pozidriv) or PH (Phillips) drive, matching the wood screws
- Folding rule or tape measure
- Pencil
Step 1: Removing the Old Hinges
Undo the screws on the cruciform mounting plate inside the carcase. Remove the door and lay it flat on a soft surface. Next, undo the screws on the hinge cup and carefully lever the cup out of the 35 mm recess.
Step 2: Installing the New Cup Hinges
Place the new soft-close hinge into the recess of the door. Align the hinge at a 90-degree angle to the door edge. Secure the cup using suitable chipboard screws (typically 3.5 mm x 15 mm).
Step 3: Attaching the Mounting Plates
Screw the new mounting plates into the predefined 5 mm holes in the carcase (System 32). Ensure that the height matches the position of the hinges on the door precisely.
Step 4: Hanging and Adjusting the Door
Guide the hinge arm onto the mounting plate. With modern clip-on hinges, the arm engages audibly with light pressure. The door must now be adjusted using the three adjustment screws on the hinge arm:
- Depth adjustment: Regulates the gap between door and carcase (usually via an eccentric screw).
- Height adjustment: Raises or lowers the door via the slotted holes on the mounting plate.
- Side adjustment (overlay): Aligns the door parallel to the outer edge and corrects the door reveal gap.
Frequently Asked Questions (FAQ) on Compatibility and Damping
Do I need to replace all hinges on a door with soft-close variants? Technically, for light to medium-weight wardrobe doors, a single soft-close hinge per door is often sufficient to produce the braking effect. For heavy or very tall doors (using three or more hinges), using two soft-close hinges is recommended to ensure a smooth, even closing action.
Is soft-close the same as push-to-open? No, these are two opposing mechanisms. Soft-close brakes a door when closing and pulls it shut silently (requiring a handle). Push-to-open (or tip-on) pushes the door open after light pressure on the front (for handleless designs). Both systems cannot generally be combined within the same hinge.
Which dampers do I need for lift-up flaps above the wardrobe? If you are using top bridge units or overhead modules with upward-opening flaps, standard hinges are not used; instead, you need gas struts. The force of these cylinders is measured in Newtons (N). For heavy MDF or solid timber flaps, you will require gas struts for heavy flaps with an appropriately high Newton rating (e.g. 120 N or 150 N), calculated according to the precise flap weight.
Do these hinges also fit other IKEA furniture? The 32 mm system and 35 mm cup are industry standards. Therefore, hinges with these specifications are not only suitable as an alternative to Pax components, but are also often compatible with kitchen systems (Faktum, Metod) or living room furniture (Besta), provided the overlay type (full overlay, half overlay, or inset) is selected correctly.
