When using our Trailer Restraint System, most people will replace their cotter pin(if their axle nut has one) with an oversized safety pin. These may be found locally at a hardware store, or you can purchase from us.
Cotter pin functional length is 1-11/16". Wire diameter is 13 gage(0.091"). Inside clearance 0.5" width. Total product length is 2.75" x 7/8".
