Butt hinges

Left hand or right hand hinge

To distinguish between hinges with screw-on flanges, view them in open position from the front against the countersunk screw hole side.

If the female flange (= door flange) is on the left, it is a left hand hinge. If it is on the right, it is a right hand hinge.

ⓐ = female flange (= door flange)

ⓑ = male flange (= side flange)

Crank

There are 5 different types of crank.

Crank A, straight hinge

For butting inset or overlay doors.

The hinge pin is positioned centrally between the two flanges.

Crank B

For set back doors.

One flange is cranked by the material thickness.

Crank C

Crank C is equivalent to crank B, but causes the door to protrude.

Crank D

For rebated doors, with shorter female flange.

Crank L1

For butting overlay doors. Door opening angle 270°. The hinge has an external knuckle.

Number of furniture hinges per door

The number of concealed hinges per door depends on:

• Door width and height
• Door weight
• Door material

The number of furniture hinges shown in the diagram is a recommendation and provides a guideline for 600 mm wide doors made from 19 mm chipboard. Trial mounting is recommended. The distance X between the furniture hinges must always be as long as possible for stability reasons.

According to the example diagram two furniture hinges have to be fitted with a door height of 900 mm.
