This kit allows you to install Optitap mechanical hardened connectors, in the field, on roc drop cable. This kit saves you money because it assumes you already have the tkt-Unicam kit, cam tool and a Corning fiber optic cleaver. This is brand new and ready to go, it was an extra from our tech deployments. I am an FOA trained fiber optic technician, I have reviewed this kit myself, and also have one on my truck.
