How to Adjust a Kitchen Cupboard Door Concealed Hinge

All of these adjustments can take place while the door is in position. The images below is a close up of a concealed hinge, each adjustment screw is numbered. Follow the instructions below to adjust the door to the number of the adjustment above.

Please note screwing tight is a clockwise turn, unscrewing is anticlockwise

• Adjustment number 1: (Door lifted higher) is done by undoing screws 2 and 4 on both hinges and lifting door to required height. Hold in position and tighten screws
• Adjustment number 2: As above but lower door and tighten screws
• Adjustment number 3: Screw tight number 1 on the top hinge and/or unscrew number 1 on the bottom door
• Adjustment number 4: Unscrew number 1 on the top door and/or screw tight number 1 on the bottom door
• Adjustment number 5: Unscrew number 1 on the top door and/or screw tight number 1 on the bottom door
• Adjustment number 6: Screw tight number 1 on the top hinge and/or unscrew number 1 on the bottom door
• Adjustment number 7: Unscrew number 3 on both hinges, move door over and tighten
• Adjustment number 8: Unscrew number 3 on both hinges, move door over and tighten
• Adjustment number 9: See adjustment 1
• Adjustment number 10: Screw tight number 1 on the bottom hinge

Any one or more of these adjustments can be made at the same time, for example if the top corner (B) of the door needs to go up a great deal, you can make the adjustments shown in adjustment 5 while at the same time unscrewing number 3 in the bottom hinge and pulling out slightly

Remember that moving a door left or right by just using screw 1 will tilt the door also, This can be compensated by unscrewing the equivalent screw on the other hinge or making necessary adjustments with screw 3.
