Technovision grip rings are bidirectional rings that can be applied in either direction, thus providing the following advantages.


These grip rings are the only ones available that can be applied in either direction.

Even in an assembly process involving heavy use of grip rings, these rings relieve operators of the need to perform time-consuming and troublesome direction checks.

This in turn relieves them of pain in their hands and fingers, significantly improving their work efficiency.

Prevents tapes and films from tearing or breaking.
Eliminates the need to check the direction of the grip ring.
Allows even unskilled operators to do work safely.
The rings have no sharp edges that would hurt hands or fingers.
Further prevent tapes and films from tearing or breaking by eliminating projections (gate) caused by plastic injection.
