110° Soft-Close Concealed Hinges: How to Choose Standard Hinges Correctly

December 21, 2025

A concealed hinge with a 110° opening angle and integrated soft-close damping is the technical standard for furniture doors, enabling silent closing and protecting the cabinet carcase from vibrations through smooth deceleration.

When constructing or repairing carcases, kitchen units, and wardrobes, choosing the correct hinges is essential for long-term durability and clean door reveals. An opening angle of 110° provides the ideal balance between wide internal access and space-saving door movement. The integrated damper, typically housed in the hinge arm or hinge cup, cushions the door over the final centimetres of its closing travel. This guide details the technical specifications fitters and joiners need to select the exact fitting required.

Key Purchasing Criteria for 110° Soft-Close Concealed Hinges

The specifications of a hinge must precisely match the board thickness, drilling pattern, and door position. Pay attention to the following technical parameters:

Cup Diameter and Drilling Depth

The standard hole diameter in furniture making is 35 mm. For very narrow frames or thinner boards, specialist versions with 26 mm are available. The routing depth for the cup on most soft-close models is between 11.5 mm and 13 mm. The door thickness should therefore be at least 15 mm to prevent drilling through or tearing out the cup hole.

Drilling Pattern and Mounting Plate

The drilling pattern defines the distance between screw holes beside the cup. Common spacings are 45 mm or 52 mm. The hinge is clipped or screwed onto a cruciform mounting plate fixed to the inner carcase wall. These plates generally follow the System 32 standard, where row holes are spaced 32 mm apart and set 37 mm back from the front carcase edge.

Tool-Free Installation

Modern fittings utilise clip-on mounting. The concealed hinge is simply pressed onto the mounting plate without tools until it audibly clicks into place. This saves significant time during the final assembly of kitchens or large wardrobe units.

Cranking Types: Which Hinge for Which Application?

The position of the closed door relative to the carcase side determines the required cranking (the bend in the hinge arm). Choosing the wrong crank is the most common mistake when sourcing replacement hardware.

Full overlay: The closed door sits almost entirely over the side carcase panel. Only a narrow reveal of around 1.5 mm to 2 mm remains visible. The hinge arm on this variant is straight (uncranked).
Half overlay (twin overlay): When two doors share a single intermediate dividing panel, they must share the front edge of the board. Each door covers only half the edge. The hinge arm features a slight crank (bend).
Inset: The door sits fully flush within the outer carcase edges, positioned between the side panels. The hinge arm has a pronounced, deep crank.

Damping Mechanism: Sizing Soft-Close Correctly

Integrated damping acts like a vehicle shock absorber, smoothly absorbing the kinetic energy of the door. When choosing concealed cabinet hinges with soft-close damping, the door weight is the decisive factor.

The damping resistance on quality hinges is designed for standard MDF or chipboard fronts. On very light doors, the damper may provide too much resistance, preventing the door from closing fully. To resolve this, some models feature a small switch on one of the hinges to deactivate its damper.

The number of hinges required depends on the height and weight of the front:

Up to 900 mm height / 5 kg: 2 hinges
Up to 1600 mm height / 9 kg: 3 hinges
Up to 2000 mm height / 15 kg: 4 hinges
Up to 2400 mm height / 22 kg: 5 hinges

Special Applications: When 110° Is Not Enough

A 110-degree cabinet hinge covers roughly 90% of standard installations. However, specialised carcase configurations require different opening angles or angled hinges:

Corner units with wide access: When internal pull-out drawers are fitted, the door must clear the full internal opening. In these cases, 155-degree or 165-degree concealed hinges are used to swing the front completely clear.
Angled cabinets: For angled carcases (such as under eaves or in bespoke kitchen layouts), 30-degree or 45-degree concealed hinges are required.
Blind corners: In corner sink units with a fixed blanking panel, 90-degree hinges are used to mount the door directly to the face frame or panel.

Installation Guide for 3D Adjustment

Once the front is mounted, the door gaps must be accurately aligned. Soft-close 110° hinges typically offer 3D adjustment via adjustment screws on the hinge arm:

Depth adjustment: Regulates the gap between the door and the front edge of the carcase. This ensures the door does not bind against the carcase during opening and allows the damper to engage properly.
Side (lateral) adjustment: Alters the reveal width between adjacent doors or the edge of the carcase (typically ± 2 mm).
Height adjustment: Carried out on the cruciform mounting plate (usually by loosening the fixing screws or turning an eccentric cam screw) to align the door vertically.

FAQ – Frequently Asked Questions About Soft-Close Hinges

Can soft-close hinges be combined with push-to-open mechanisms? No. These two mechanisms are mechanically incompatible. A soft-close hinge actively pulls the door shut and decelerates it over the final millimetres. A push-to-open system requires an unsprung hinge, as the door must be free to pop open when pressure is applied to the push catch.

Why is my cabinet door not closing fully despite soft-close? This is usually caused by one of two issues: either the door is too lightweight to overcome the damper resistance, or the depth adjustment is set incorrectly, causing the hinge arm to mechanically bind before completing its full travel.

What cup diameter do I need for a replacement? Measure the existing hole in the door using a calliper. If it measures 35 mm, it is the standard industry size. If it measures 26 mm, you will need a mini concealed hinge.

How should soft-close hinges be cleaned and maintained? The internal mechanism is maintenance-free and lubricated at the factory. Clean only using a dry or slightly damp cloth. Never spray penetrating oils (such as WD-40) into the damping cylinders, as this will break down the viscosity of the internal damping fluid.
