Can these tubes be cut in half? 48 inches is too long for my application. If I can cut these tubes in half and use the shorter pieces it would be perfect.

Answer: 
Yes, we used a circular saw and cut to the 3 ft. length we needed. A hand saw would work too. They are a little thick for a razor blade knife.

Answer: 
Yes. I use a table saw. Raise the blade just far enough to go thru the tube wall about an inch. Move the fence to the length you want and place one end of the tube against the fence and move onto the blade and just turn the tube until you cut all the way thou. Gives you two straight ends.

Answer: 
The 8 inches is a nominal diameter. Some tubes could be 8,25" and others could be 7.75" etc. This is done to cut done on space in shipping, so the tubes will fit inside of each other. Four of the 8" tubes shipped together will vary accordingly. If you need an exact size, you may have to visit a couple of stores or measure the tubes that they have in stock.

Answer: 
Thank you for your inquiry. These tubes may vary ± .5 inch because they are designed to slide into one another in instances where multiple form tubes of the same size are purchased. I would recommend going to the store and measuring if you are looking for an exact size for your project.

Answer: 
Thanks for your question. The tube is approximately 1.4 cu. ft and each 80lb bag of concrete yields approximately .6 cu. ft. Given this, you will need to purchase 3 80lb bags of concrete to completely fill the tube.

Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Ideal Form Tube For Setting 4x4 Posts This form tube is easy to use and helps to simplify the process of setting concrete for posts or columns. The manufacturer provides printed instructions on the outside of the tube form. Most important is that this form tube which is made of treated cardboard must be completely dry prior to concrete being poured into it for the tube form to maintain maximum strength and integrity. The manufacturer also specifies the amount of concrete mix required per foot on the outside of the form tube to fill the length of the form tube. The diameter of the form tube is +/- 0.5 inch to make it cheaper and easier to ship several form tubes by nesting them inside of each other. I used three 80 pound bags of concrete mix to fill all of the 48" length of this 8" diameter tube form and had some concrete left over. It is always better to have some concrete left over then it is to not have enough concrete because concrete must be mixed properly and poured all at once for all of the concrete to bond correctly as one solid mass before the concrete sets. The 8" diameter of this form tube is an ideal size for setting 4x4 posts since the Strong Tie post bases recommend 2" of concrete on all sides of their bases. 8" diameter is also just large enough to be able to use a spade shovel to compact the concrete as it is poured into the tube form.

Rated 5.0 out of 5.0 by Makes pouring footings easy These are the only way to go if you have to pour footings for under a deck or anything else. Just dig a hole to the depth you need, check local codes, cut to length, drop it in the hole and back fill around the outside for stability. You are ready to pour. Having a nice straight end makes setting the tops level on multiple footings easy with a string line. February 3, 2016
