2 individually adjustable blades for non-standard and standard cables1/4 in. strip between blades; open end for variable conductor lengthsDesigned for use on RG-58/RG-59/RG-6/RG-6QuadSpring loaded handles - 5-7 rotations for most cablesHex wrench included in handle for blade depth adjustmentsOne of our original styles of coaxial cable strippers for RG-58/59/6/6 Quad coax. What makes these products unique is that each blade is individually adjustable so if you are working with a non-standard type of coaxial cable (thicker jacket or thinner dielectric 50O cables, for example) the blades can be positioned according to the cable dimensions for a precise cut. If the traditional industry standard x prep tools just wont work for your application, these are the products to try.A 3 position top side slide bar adjusts the cable V-notch size for fast adjustments of different diameter cables.Each tool includes a hex wrench stored in the handle. It is used to adjust the hex set screws to change the depth of each blade. The 45-520 is a 3 blade model that is designed to offer a shield exposure, dielectric exposure, and conductor exposure. Conductor exposure is variable, up to . This is primarily used in legacy RF crimp connectors. It is not used with modern day compression connectors. The third blade can be recessed to a no-cut position to allow the 45-520 to operate as a standard 2-step stripper.
