1) For Mounting - A Flange or just an EMT End Connector - you can ether use a 1/2" or 3/4" pipe flange as a connection point to your substrate OR you can use the 1/2" and/or 3/4" EMT fitting that we are showing screwing into those as a connection system to a substrate (see product guide for details)

2)  Posts - You can use 3/4" conduit for tubing or you can use a combination of 1/2" and 3/4" tubing for telescoping applications.   The Brackets are purchased for 1/2" EMT but for this to work properly, they have to be installed on 3/4" tubing (I know, that can be confusing for some, but that's what made this system work with standard components).  If for some reason you wanted to try to use our brackets directly on on 1/2" tubing only, you need to add a simple bushing and you may need to add a locking screw depending on the weight of the item being held up.   One time it might make sense to try to attach these to 1/2" posts vs 3/4" is if you were doing dozens, hundreds or thousands, where the cost of the 3/4" posts was something you wanted to reduce.  The other time is if you wanted to intentionally add some color to the system, just for aesthetics. 

3) Brackets - We offer a 3 AXIS bracket and a 3/4 AXIS combo bracket.  These are ideal for a mounting plate for a monitor but they may have other connective uses.  They are designed to connect the mounting plate to the post with a single bracket but two brackets can be used per mounting plate we are providing for added strength. 

4) Monitor Mounting Plate - we offer a an aluminum/plastic composite mounting plate that is ideal for small to mid size monitors and it may work for larger monitors too. It comes with standard 75x75 and 100x100 mounting hole patters along with additional holes. It can also be easily drilled for other needs. 

See Catalog and Product Guide for more Details.  (links at top of page)

3/4” tubing only for post  - You can do a non telescoping stand with just 3/4” tubing.

1/2” tubing only for post  -   You can just use 1/2” tubing for the post but if you do that you will need to buy low bushings for the brackets and you will likely need a locking nut on the rear of the bracket too.  You would need a reason to do this as opposed to just using 3/4” since there is no material price difference and more components required for use. 

1/2” tubing for telescoping  -  If you want it to telescope, for a 2 piece telescope  you need 1/2” emt for the inner pipe and 3/4” emt for the outer. The outer can be longer, the same length or far shorter than the inner. They do not have to be the same length. It depends how much you want to telescope.  For a 3 Piece telescope you have 3/4” outside, 1/2” inside and 3/4” outside. This might be relevant if you want a tall stand that is rigid, with easier telescoping needs.
----- 

For 2 monitor mounts on a telescoping system,  the 3/4” piece needs to be a minimum of the height of the monitor plus 2”. That would leave no room to spare. We suggest a 3-4” more than that just for some room to flex and the post stick up can make for a good place to hand wires from.

These are sold at hardware stores in 10’ lengths for around $6 and $10 respectively.

Thus, for  $16 plus tax you can buy on piece of each and you have enough  for 5 to 10 stands if you are doing smaller stands. 

 We use commercial chop saw and $45 deburr tool but there are lower cost ways to do it.  ‘

You will need a cutting tool and a debur tool of some type.

The company “Maker Pipe” has a good video on cutting EMT with a manual wheel cutter that has an internal debur tool built in. The recommend the Brass Craft brand.
