FAQ Section

How do I choose the right Trailer Screw Jack for my trailer?

Consider the weight of your trailer when fully loaded, and select a jack with a capacity that exceeds this weight by at least 20% for safety. Also, factor in the height range needed for your typical use and the type of base (swivel or fixed) based on the ground conditions you encounter.

Can a Trailer Screw Jack be used on all types of trailers?

Yes, these jacks are universal and can be installed on most trailers, including utility, boat, camper, and equipment trailers. Ensure the jack's mounting system is compatible with your trailer's frame, and always follow the manufacturer's installation guidelines.

How do I maintain my Trailer Screw Jack to ensure longevity?

Regularly clean the jack to remove dirt and debris, lubricate the screw mechanism with a high-quality grease every few months, and inspect for signs of wear or corrosion. Store it in a dry place when not in use to prevent rusting, especially for steel models.

What is the difference between a fixed base and a swivel base?

A fixed base is stationary and ideal for solid, flat surfaces, providing strong support. A swivel base can rotate and adapt to uneven ground, offering better stability on soft or angled terrain. Choose based on your typical operating environment.

Is it possible to over-extend a Trailer Screw Jack?

Yes, over-extending beyond the maximum height can damage the screw mechanism or cause instability. Always operate within the specified height range and avoid putting excessive side load on the jack, which could lead to bending or failure.

Can I use multiple Trailer Screw Jacks simultaneously for heavier loads?

Yes, for trailers with higher weights or uneven weight distribution, using two or more jacks is common. Ensure they are of the same model and capacity, and position them symmetrically to distribute the load evenly and prevent tipping.
