Weight Distributing Capacity (WD)拓松汽车户外网 -)~0b\NX']!~N

The measure of the total weight a trailer hitch can safely pull with a weight distribution system installed. The use of a weight distribution system balances the weight of the cargo throughout the trailer, allowing for better steering, braking and level towing.

V8n*G2J$}0Tongue Weight (TW)

CR-u:H\5tbj9G0The downward force that is exerted on the trailer 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 bathroom scale reading by three.

"gNaT g9~N`"w0Safety 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 the vehicle can safely turn. Never allow the safety chains to drag on the ground and never attach the chains to the bumper. CURT offers chains in a variety of capacities to meet your towing needs. Each safety chain or safety cable must equal or exceed the gross trailer weight rating of the trailer.
