3D Adjustable Concealed Hinges: How Much Each Model Adjusts

Updated 2026-11-08 · RAYEN 雷茵

What does each direction correct?

• Up and down: raises or lowers the whole door. Use it when the door rubs the floor or the head, or when the top gap is uneven between doors in a row.
• Left and right: moves the door towards or away from the hinge side. Use it to even out the gap down the lock side, or when the latch misses the strike.
• Front and back: moves the door face in or out of the frame. Use it to bring the door flush with the frame, or to press it evenly onto the seal.

The hydraulic models call the third direction in and out. It is the same movement under another name, and the Chinese drawings use one word for both.

What should you check?

• Door weight and thickness. These pick the model.
• The tolerance your fitter works to, in mm, on height, gap and flush.
• Whether the door must also close itself. If so, look at the hydraulic models below.
• How many doors you hang in a row. Adjustment saves most time on a long run of matching doors.

Concealed hinge adjustment by model

Only the models with a range appear with figures. Read the pattern:

• Up and down is ±3.0mm on most models. RY140 and RY80J give ±2.5mm, and RY80 gives ±1.5mm.
• Left and right is uneven on R-CC120J, R-CF120 and RY120: +3.5mm one way, -2.0mm the other. Elsewhere it runs from ±1.5mm to ±3.0mm, the widest on R-CC200 and RY177.
• Front and back is the smallest movement on most models, ±1.0mm to ±2.0mm. RY80J gives ±2.5mm.
• RY80 adjusts in two directions only, up and down and front and back, at ±1.5mm each.

The R-CS models list no adjustment, so they need an exact cut. The EDA models are named 3D adjustable but print no range, so ask us for the figures before you rely on them.

Hydraulic concealed hinges

If the door should also close by itself, the RY8001–RY8004 series combines both.

All four give ±1.0mm in and out. Up and down is ±2.5mm on RY8001 and RY8004, and ±2.0mm on RY8002 and RY8003. JL607, JL608 and JL609 are also named three-dimensionally adjustable, without a printed range. The hydraulic hinge guide covers their loads.

Is there an adjustable butt hinge?

Yes. 4x4x2.5-3D is a visible hinge with adjusting screws on the leaf. Its leaf is 103 × 102mm and 2.5mm thick, in iron and zinc alloy. No range is printed, so confirm it with us.

A worked example

A hotel corridor has thirty 45mm timber doors at 70kg, hung flush with the wall. The fitter works to a 3mm even gap and wants each door flush within 1mm. RY120 carries 120kg on two hinges, needs a door of 40mm or more, and gives ±3.0mm up and down, +3.5/-2.0mm side to side and ±1.5mm front and back. That covers the gap and the flush with room to spare. RY100 would also carry the door, at 100kg, but gives ±1.0mm front and back, which leaves no margin on the flush.

If those doors must close by themselves, RY8001 on two hydraulic hinges and one plain carries 80kg, with ±2.5mm up and down and ±1.0mm in and out.

Does the frame need anything?

Yes. A concealed hinge sits in a pocket in the frame as well as in the door, and the adjustment only works if both pockets match the drawing. On aluminium or thin metal frames, check the routing depth first.

What should you write on the order?

• Model, such as RY120.
• Door weight, thickness, height and width.
• The adjustment you need, in mm, if your specification sets one.
• Hinges per door, and the set for hydraulic models.
• Material grade and finish.
