This is a new Compression Cable Connector manufactured by Gilbert.  Due to their recent patent dispute with PPC, the design has been changed so the connector crimps from the top instead of the bottom.

The new Gilbert connectors are excellent quality and crimp very easily with a compression crimper. 

Although its not recommended, and since these connectors crimp from the top, instead of the bottom like traditional connectors,  we have had some of our customers report that they can install these connectors without a crimper by simply threading on a barrell connector and using a 7/16 wrench to tighten it up.  See Below.....

Tools needed are (2) 7/16 Wrenches, Cable Stripper and a Barrel connector

Step #1 Strip the Coax
