XINQIAO Cabinet Jacks for Installing Cabinets, Heavy Duty Third Hand Tools Adjustable Support Pole from 23.6 in to 45.3 in, 1 PC

I purchase these jacks to support my air conditioners. I had used 3x3 wood posts previously,but every time you get a new a/c the post need to be replaced to fit. These jacks are adjustable and will never have to be replaced.

Super useful to work over head when you are a single person

I used this to reinstall some paneling on my shower ceiling. Great idea but the clamp to tighten the pole leaves something to be desired. It kept slipping down when using the lever. Had to use a hose clamp to keep its position. But still a good product

Very sturdy and it gets the job done.

We used these as dust containment poles during our tile floor demo. It made putting up barriers so much easier. Recommend.

These are a great purchase. It’s like having an extra set of hands very strong very durable.

I purchased this product to serve as a reinforcement for a wall mounted closet and I was impressed by the quality as it was perfect for my needs. However, the spring loaded pins for two of the support rods refused to deploy. I made multiple attempts to get the pins to deploy using a small screwdriver with no luck. For one of them the pin fell back into the rod so there's no chance of me being able to get that fixed. I'm going to get bolts or external pins from Home Depot and use them in place of the pins that came with the rods because I just don't want to go through the hassle of packing these up and returning them. Just something to keep in mind if you are thinking of purchasing these.

As promised...works well
