Rolled lift-off hinges

Rolled lift-off hinges are 2-part hinges. The upper lift-off hinge part rotates on the lower part (in hinges the fingers of the hinge parts rotate together). The pin is attached to the lower lift-off hinge part. The advantage of lift-off hinges (weld-on hinges) is that the valve or door is easy to place and take out. Rolled lift-off hinges are made to measure for you. So you specify your wishes, matching your construction.

The end play is the light axial movement between the knots over the axis of the pen. This is caused by the small space between the nodes, which causes the leaf to hinge.
