Material: zinc alloy + PTEE (heat resistant) Type: solderless Outer: nickel plated Scale maximum 12mm of the outer jacket from the cable, then strip 5-7mm of the insulation to expose the center core, slide the rubber liner for the jacket onto the cable, loosen the brass screw in the center of the connector and bend the center core around it - then tighten to hold the core in place (not too tight as it can arc to the outside when everything is assembled). Straighten the clamp strip and insert the insulation with braid covering the metal. Once assembled, use a proper crimping tool to secure the clamp to the braided section. Pull down the rubber liner to the metal connector and push it into place! Can be used on CCTV, DVR, DVR cards, Multiplexers, Switchers, and anything else that has a BNC input/output. Size: 5x1.4cm/1.97x0.55inch Note! Please allow 1-3mm error due to manual measurement. Make sure you don't mind before bidding.
