VEVOR Adjustable Steel Jack Post, 53-93 in: specs and what to check

The VEVOR adjustable jack post is a telescoping steel column designed to hold up a beam, joist or floor while work is carried out. It is often called a basement jack or screw jack post. The idea is simple: a steel pole between the floor and the load, with an adjustable length. Here is what the listing gives and what the numbers mean.

What a jack post does

A jack post carries a load straight down through its column into the floor. Typical uses are temporary support during repairs, levelling a sagging beam, and supporting floors, patios or construction while permanent work is done. VEVOR lists beams, patios and construction as example uses. The listing says the post is for temporary support.

Load limit

VEVOR says each post handles up to 18,000 lb (about 8,165 kg) and is built from Q235 steel, a common structural carbon steel grade. A load limit is a maximum, and manufacturers' figures assume a straight, centred load on a solid, level base. Any real installation should be sized by someone qualified, who can work out how much weight the post will carry. Follow the manual and local building codes.

Height range

The post adjusts from 53 to 93 inches (134.6 to 236.2 cm). That covers many basement and crawl-space ceiling heights, but measure your own space from floor to the underside of the beam, allowing for the base plate and top plate. A wide range lets one post suit several jobs.

Adjusting it

VEVOR says you adjust the height by turning the lever with no extra tools. Two lock pins are included to secure the setting. The coarse adjustment normally comes from the pin position, with the fine adjustment from turning the screw. Ensure the pins are fully seated before any weight is applied.

Welded base plate

The base plate is welded to the pipe in one piece, which VEVOR says removes the need to fix the plate to the pipe and makes installation quicker. A flat, welded base helps keep the post upright on the floor. The listing gives the dimensions as 53 x 6 x 4 inches, which is the size of the post in its shortest form.

Who it suits

It suits renovators, contractors and homeowners who need temporary support while replacing a beam, fixing a floor or levelling a structure, as long as the work is planned and checked by a qualified person where needed.

What to check before you buy

• Required height: measure floor to beam and make sure it falls inside 53-93 inches.
• Load: have the load estimated properly. Don't rely only on the listed figure.
• Floor condition: a post needs firm, level concrete or a spreader plate under it, as the manual describes.
• Plumb: the post must stand vertical, not tilted.
• Temporary or permanent: the listing says temporary support. Permanent columns have their own code requirements.
• Local codes: check building rules and whether a permit or an engineer is required.
