Retrofitting Soft-Close Dampers for Pelipal Kitchens

A soft-close system decelerates the closing movement of furniture doors or drawers using an integrated hydraulic cylinder and pulls them shut silently over the final millimetres.

When modernising or repairing kitchen units, reducing noise and material wear is often the primary focus. Older cabinets or basic configurations frequently feature non-cushioned fittings that slam loudly against the carcase upon closing. Retrofitting damping is a standard technical task that can be carried out precisely with the correct components. If you are looking for replacement parts compatible with Pelipal or similar kitchen manufacturers, dimensional accuracy is the sole deciding factor for a successful installation.

What to Look for Regarding Compatibility

To ensure smooth operation, the new hardware must match the existing drill holes and routings in the cabinet carcase and the door front exactly. The furniture industry predominantly relies on standardised dimensions.

Hinges and Concealed Cup Hinges

The central connecting element in kitchen cabinets is the concealed cup hinge. If you want to replace an un-damped hinge with a version featuring integrated soft-close, three technical parameters are critical:

1. Cup hole: The diameter of the recessed hole in the furniture door is usually 35 mm. Smaller 26 mm variants are rare in standard kitchens. The depth of the hole typically ranges between 11.5 mm and 12.5 mm.
2. Hole pattern: Mounting plates are almost always fastened to the carcase following the System 32 standard. This means the distance between the drill holes is precisely 32 mm. The standard setback from the front carcase edge to the first row of holes is 37 mm.
3. Cranking type: This is where most mistakes happen. If the door fully overlays the side panel, you require a full overlay hinge. If two doors share a central partition, a half overlay hinge is needed. If the door sits flush inside the cabinet opening, an inset hinge is required.

Drawer Runners

For pull-outs, the available installation width between the drawer side and the carcase inner wall is the most crucial dimension. A standard ball-bearing slide generally requires 12.7 mm of clearance on each side. In addition, the nominal length of the runner must match the depth of the drawer. Common lengths in kitchens range from 250 mm to 800 mm. A full extension runner provides the benefit of allowing the drawer box to pull out 100% clear of the carcase, whereas a single extension stops at around 75%.

Suitable Replacement Parts for Retrofitting

If you are looking for fittings to serve as an alternative to original Pelipal parts, various technical solutions are available.

Complete Hinge Replacement

The cleanest approach is replacing old hinges entirely with concealed cup hinges / cabinet hinges with damping (Soft Close). These components have the hydraulic cylinder invisibly integrated into the hinge arm. As long as the cup diameter of 35 mm and the hole pattern match, these hinges can easily replace existing kitchen hinges.

Clip-On Dampers and Door Buffers

If you prefer to keep your existing concealed cup hinges / cabinet hinges on the carcase, you can add soft-close retrospectively. A clip-on damper acts like a vehicle shock absorber, gently absorbing the kinetic energy of the closing door. Alternatively, you can use door dampers that are either recessed into a 10 mm hole in the carcase edge or surface-mounted using an adapter housing. Simple silicone buffers & dampers will also reduce slamming noise, although they do not provide active closing deceleration.

Converting Drawers to Soft-Close

To ensure gentle closing of cutlery or pan drawers, the runner mechanisms must be replaced. Drawer runners with damping catch the momentum of the pull-out over the final 30 mm to 50 mm and draw it closed using spring force. If you need maximum access to the rear of the drawer box, opt for drawer runners full extension, ordered to match your specific drawer depth.

Wall Units and Lift-Up Flaps

Kitchen wall cabinets are often fitted with upward-opening flaps. Here, gas struts keep the flap open and allow gentle closing. Selecting the correct replacement part depends on the weight of the MDF or chipboard panel. The force rating is specified in Newtons. For wide fronts, gas struts for heavy flaps rated at 250 N or 320 N, for instance, are required.

Installation and Retrofitting: Step-by-Step

Replacing hardware requires precision work, but it can be carried out using standard tools.

Required Tools

• Cordless drill/driver
• Matching bits (typically PZ 2 or TX 20)
• Folding rule or tape measure
• Try square
• Forstner drill bit (35 mm) if creating new cut-outs

Replacing Hinges

1. Dismantling: Release the door by pressing the release clip (on clip-on hinges) or by undoing the securing screw on the hinge arm.
2. Remove old hinges: Unscrew the old hinges from the door and the mounting plates from the carcase.
3. Fit new mounting plates: Secure the new cross mounting plates exactly into the existing 5 mm system holes.
4. Fit cup hinges: Insert the new soft-close hinges into the 35 mm cup holes in the door. Ensure a precise 90° angle to the door edge and screw them in place.
5. Hang and adjust the door: Clip the hinges onto the mounting plates. Use the adjustment screws on the hinge arm to align height, depth, and side overlay (gap reveal), typically within a +/- 2 mm range.

Replacing Drawer Runners

1. Remove drawer: Pull the drawer out and lift it over the stops to release it from the runners.
2. Dismantle old runners: Remove the carcase tracks and the profiles attached to the drawer box.
3. Mount new carcase runners: Take meticulous care with horizontal alignment. Use the system holes in the carcase. The front edge of the runner is usually mounted flush or set back 2 mm from the carcase front edge.
4. Screw on drawer profiles: Fasten the matching profiles to the lower side edges of the drawer box.
5. Functional test: Slide the drawer into the carcase until the ball-bearing mechanism audibly engages. Test the soft-close travel.

Frequently Asked Questions (FAQ)

Can I retrofit soft-close to any kitchen? Yes, provided the units were manufactured to standard industry dimensions. Replacement parts are almost always compatible with Pelipal and other brands if the carcase uses the 32 mm system and the door features a 35 mm cup hole.

Do I need to replace all hinges on a door with soft-close hinges? On small, lightweight doors, it is often technically sufficient to equip just one hinge with soft-close while leaving the other as a standard hinge. However, for optimum, balanced closing and on heavier doors, all hinges should have an integrated damping cylinder.

What is the difference between soft-close and push-to-open? These two systems serve opposite functions. Soft-close slows a door down upon closing and gently pulls it shut. Push-to-open (or tip-on) is an opening mechanism for handleless fronts that pushes the door slightly open when the front panel is pressed. These two systems cannot be combined in a single standard fitting.

How do I find the correct rating for flap gas struts? The required force in N is calculated from the weight of the flap including its handle. As a general guideline, 1 kg of flap weight requires approximately 10 N of holding force. Measure or weigh the front panel to determine the exact value needed.
