The majority of modern uPVC doors feature “Flag Hinges,” which enable three-way change:

• Lateral Adjustment: Moves the door left or right.
• Vertical Adjustment: Moves the door up or down.
• Compression Adjustment: Moves the door more detailed to or further from the frame to enhance the seal.

Euro-Cylinder Locks
