## At a glance

- The central threaded rod adjusts the support height, and the listing says to set the height before loading because adjustment may be difficult once loaded.
- A spanner and glove are listed among the included components.
- The listing describes use for floor leveling, joists, beams, decks, porches and auxiliary RV step support.

## Pros

- The stated 11–16-inch range suits support points that fall within that height window.
- An eight-piece set is presented for supporting larger areas or multiple projects.
- A wrench and glove are listed in the package contents.

## Cons

- The stated height range is limited to 11–16 inches, so it will not suit support points outside that span.

## Before you buy

- The manufacturer says to set the desired height before loading, as raising the jack after loading may be difficult. On gravel or slightly uneven ground, it recommends a hard steel plate or wooden board beneath the base and prohibits bricks or fragile materials. The listing also says these are auxiliary support only for RV use, not a substitute for a professional vehicle jack or safety stand.

## In the box

- 6 adjustable house floor jacks (Included)
- 1 glove (Included)
- 1 wrench (Included)

## A good fit for

- DIYers supporting floor joists, beams, decks or porch structures at heights within the listed range.
- RV owners seeking auxiliary support for steps, rather than a vehicle-lifting jack or safety stand.

## Less suited to

- Buyers needing supports shorter than 11 inches or taller than 16 inches.
- Vehicle lifting or primary RV safety support.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the four- or five-star categories, but the overall picture is limited by the small number of ratings and includes some three-star feedback. The figures do not explain what customers liked or disliked. Buyers should judge fit against the listed 11–16-inch range and treat the 5,000 lb capacity as a manufacturer claim, not customer-verified performance.

## Frequently asked questions

### What height range does the listing give?
It lists adjustment from 11 inches to 16 inches, approximately 28 cm to 40.6 cm.
### Can these be used to lift an RV?
The listing says they are not a substitute for a professional vehicle jack or safety stand and should be used only as auxiliary support in emergency situations.
### Should the height be adjusted under load?

It recommends a hard steel plate or wooden board. It specifically says not to use bricks or fragile materials.
