Tongue Weight (TW) The downward force exerted on the hitch ball by the coupler. The tongue weight will vary depending on where the load is positioned in relationship to the trailer axle(s). To measure the tongue weight, use either a commercial scale or a bathroom scale with the coupler at towing height. When using a bathroom scale, use the method shown and multiply the scale reading by three. Sway Control A device used to reduce the lateral movements of the trailer that are caused by the wind. This may be used in conjunction with a weight distribution hitch or alone. Do not use this on a class I or II hitch, or with surge brakes. Safety Chains Safety chains are required by law and should be crossed under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Always leave enough slack so you can turn. Never allow the safety chains to drag on the ground and never attach the chains to the bumper. Trailer classification: safety chain breaking force-minimum Class I: 2,000 lbs. (8.9 kN) Class II: 3,500 lbs. (16.5 kN) Class III: 5,000 lbs. (22.2 kN) Each safety chain or safety cable must equal or exceed the GTW of the trailer. Trailer Balls Connection from the hitch to the trailer. There are many factors that determine the correct hitch ball: Most important is the hitch ball's gross trailer weight rating. The mounting platform must be at least 3/8" thick. The hole diameter must not be more than 1/16" larger than the threaded shank. Every time you tow, check the nut and lock washer to make sure they are fastened securely.
