Product Description

About the Trailer Tongue Weight Scale

The scale uses a simple hydraulic principle to convert pressure into a reading in pounds on the gauge. No delicate electronics, no batteries, and only one moving part. It is available with gauges reading to 1000 lb, 2000 lb, or 5000 lb for 5th wheel trailers that typically carry a larger percentage of the overall weight on the gooseneck.

The scale is machined from solid billet steel and aluminum. It has a 3.25″ body diameter and is about 4.5″ high without the included screw-on hitch extension. (6.75″ with extension installed.) Actual weight is 4.4 lb. Gauge diameter is 2.75″. One year guarantee.

Stop guessing and start towing safely. Reasonably priced for individual trailer owners. Great for travel clubs and trailer dealers too.

Gauges Now Read in Pounds and Kilograms

All gauges have a dual-scale gauge that reads in pounds on the outside of the ring and the kilogram equivalent on the inside. This feature has been requested by many trailer users outside the USA and has now been incorporated into all the scales.

  • The 0-1000 lb gauge reads to 460 kg
  • The 0-2000 lb gauge reads to 900 kg
  • The 0-5000 lb gauge reads to 2250 kg

Avoid Trailering Disaster!

If you tow a trailer behind your car, truck or SUV and don’t know for sure if the tongue weight is within the recommended range, you could be headed for a disaster. Too much weight and you could damage the hitch or the trailer tongue, causing a catastrophic failure on the highway. Too little weight on the hitch and you could go into an uncontrollable fishtail at highway speeds. But how can you be sure if you are properly loaded?

Once the trailer tongue weight exceeds what you can pick up by hand or weigh on a bathroom scale, many people just guess at the weight based on how far the rear end of the tow vehicle sinks when the tongue is lowered onto the hitch. This is virtually useless and a very dangerous method to depend on. To properly load and balance a trailer you must KNOW what your tongue weight is, and the Sherline trailer tongue weight scale offers an easy and inexpensive way to find out. Just jack up the tongue until it clears the hitch. Pull the tow vehicle out of the way, block up the scale and then lower the tongue receiver onto the scale. An even easier method is to release the hitch, lower the jack onto the scale and lift until the trailer tongue just lifts off the ball. Though a little behind the actual pivot point, in most cases it is sufficiently accurate to tell if you are in a safe towing range. If you know the trailer’s empty weight and the weight of the items you have put in it, you can easily calculate the percentage resting on the tongue. You can also get a total weight measurement at a local drive-on scale to have a more accurate figure. Then you can drive in safety and confidence. This is particularly important for trailers that are loaded differently each time like cargo trailers, RV vehicle trailers and the like.
