Gooseneck Style Coupler -
Model TL-50: features a 3/4" heavy duty steel locking pin. Fits most Hammerblow, Stallion, Superior, and T.E.M. Gooseneck style couplers.
Use: simply install the narrow end (looks like a goose's neck) over the coupler bracket near the handle. Bring the wide opening of the TL-50 into position over the wide part of the coupler. Insert the pin into the hole that offers the tighter connection, then install your padlock.
Padlock not included.
