No more uncertainty when inserting the cable into the connector. No more collapsed center pins. No more wasted connectors and rework time on the job.With the patented InSITE Technology feature, now standard on all IDEAL BNC and right angle (90) compression connectors, field termination of these blind entry connectors is simpler, faster and now provides a higher performance connection for all applications from CCTV to HD Video.The InSITE window is a 360 clear window which allows the installer to verify that the prepped cable has been inserted far enough into the connector to make contact with the fixed pin-before the connector is compressed. All IDEAL compression connectors require a x industry standard coax preparation. The prepped cable is then inserted into the connector until the folded braiding is visible within the InSITE window. No measuring, no jacket marking, no guesswork a confident connection every time.
