Has anyone ever used this brand?
They sell a model that extends from 19 inches to 3ft.

These posts seem to work by inserting a smaller tube into a larger one
then bolting them together. Then turning a screw to fine adjust the
height. The screw must adjust it only to a certain level before you'd
have to bolt the smaller tube higher. I've read some info that says
these posts aren't meant to be used permanently.

With the height of the post plus the height of the wood, I only need
the min height of the post so I'd never be changing the bolt positions
- both tubes would be resting on the concrete pad. So I was wondering
if I could fill the tube with concrete up the the level wherever the
screw reaches. If I fill my foundation hole with cement up to the
level where the post height & the wood height gets me to a 1/4 inch or
so I could then use the screw for the final height adjustment. Maybe
that would make the post more viable to be used permanently. After the
final adjustments were done maybe I could fill in the rest of tube with
concrete. This may be easier than trying to shim in wood if I use
cinder blocks.

I was wondering if that would actually work with this particular post.

The crawl space under the kitchen is only 2 feet high. Would solid
cinder blocks also work as opposed to an adjustable jack post? I would
think that would be better support but then I'd have to worry about
making it the right height to fit the wood beam sin snugly whereas an
adjustable post would make that part easier.

Blocks would work. It may be possible to set them in place and somehow shim
them the last inch or two. Since yo are not tryhing to raise the floor, a
snug fit of a 2 c 4 would be sufficient. It would stop downard movement and
that is your concern now.




I also have a lot of small stone in the garage that I was thinking of
dumping in the holes around the concrete tube forms rather than dirt.
Is it ok to leave the forms in the ground?

Yes and yes. Just be sure to pack in the stone as best you can.
