Poly Hook Spanners for optimal stability and RF connectivity

SPINNER’s poly hook spanners – also called C-Spanner or hook wrench – helps you tighten your connectors for ideal mechanical stability and outstanding RF performance.

While assembling a connector to a cable, the back nut has to be tightened to the connector body. Connectors for cable sizes LF 1 1/4", LF 1 5/8" and LF 2 1/4" have to be assembled by using a poly hook spanner in order to ensure optimal strength.

The best possible result can be achieved by using a poly hook spanner in combination with a SPINNER torque wrench. For precise measurement results, the connectors must be coupled according to specific standards. Furthermore, the use of torque wrenches can prevent overstraining of connectors and ensure maximum product life time at the best possible performance.

The use of SPINNER poly hook spanners helps you to reduce installation costs significantly and to maintain constant installation quality at the same time.
