Product Code:SAE J684
Title:Trailer Couplings, Hitches and Safety Chains - Automotive Type
Issuing Committee:Trailer Committee
Scope:This SAE Standard includes couplings, hitches, and safety chains used in conjunction with all types of trailers whose Gross Vehicle Weight Rating (GVWR) does not exceed 4540 kg (10,000 lb). This includes such types as utility, boat, camping, travel, and special purpose trailers which are normally towed by conventional passenger cars, light-duty commercial vehicles, light trucks, and multi-purpose passenger vehicles. This document is intended primarily for ball-and-socket type of couplings and hitches. It should not be construed as a limitation to this type alone but should apply where appropriate to ring-and-pintle, clevis-and-pin, or any other draft means designed to serve this purpose.
