TCL-3 is now available for order. Like its twin brother TCL2, this new addition to the BLOCKHEAD family utilizes an extruded, tempered aluminum body to provide superior strength to weight ratio, distinctive look, and great value. Also the same simple, rugged push button lock mechanism. Unlike its TCL-2 brother, it fits 2″ and 2-5/16″ flat lip couplers only…no adaptor to add or remove! The result is a simpler, less expensive product for those 2″ & 2-1/2″ flat lip style couplers.
