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.
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?
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.
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
NOTE on Inaccurate Gauge Reading
Is your trailer scale in a cold place (freezing or below)? If yes, this could be a factor. Cold or not, the piston has two O-rings on it. If the scale goes unused for a period of time (or if it is cold), the O-rings sometimes stick.
Hold the base down and try to turn the piston as if you were trying to screw it into the base. Then push down on it a few times (see Figure 1). If the gauge is reading 300-400 pounds with no load, then the piston is stuck. When you turn the piston, it should free it up and your gauge should go back to the “box area” at the zero end of the gauge.
CAUTION: Do not pull up on the piston. If you pull up too hard or too far, you will pull the piston out of the base.
If this fixes the problem, weigh your trailer again and see what the hitch weight is. Then remove the weight, see if the gauge goes back to the Zero box, and then check it again.
