Can you combine two of these units to increase its height?

Not safely. You can add hoses or mount the pole to something other than the tank.

You can screw another leg in to make it taller. From counter height to bar height. We love them. Very comfortable and they look good in person. Not cheap looking.

Yes you can that is what I do with mine. Has lots of extenders for height and width.

The answer is no but you can build it smaller or in different order of spaces

Yes that would be easy to do. I can lift mine of the base and add it to a built in unit at any time.

I am not sure the system will allow additional units to be added. It might be better to buy an addtional system if you a phone jack where you can plug in the additional set.

Yes you can!! We have stacked them 2 high (2 big squares) but it would be easy to add another . 2 high was just fine for the tomatoes. But I will warn you that the tomatoes do get very tall but it is nice to just reach in with very little bending.

Hi-Thanks for your inquiry-You should be able to do it as Each Raise It adds 1 inch of height.Thanks!

Dear Ron, Yes, by stacking them two high as each square riser measures 1" high.

I don't know if the seller offers this, but I know you can add additional units.

You can stack 2 by turning one upside down. More than that is not possible.

No, I don't see any way to stack it as there's no connectors that would hold a second unit securely on top.

yes you should be able to do that. each cube is almost 1 square foot so if you have your unit going two cubes side by side and 4 cubes going up then you could stack the six cubes 2 side by side and three going up on top (that would be about 7 feet tall). They do come with little wall mount brackets if you need to attach them to the wall for stabilizing or support. These are very sturdy and heavy so you would have no problems with stacking them.

Mechanically that would be possible but I doubt the unit would be very stable with double height. Another question is whether the junctions are designed for the extra weight (albeit not a giant increase) One or maybe two of the sections would be worth a try though.

No, or no unless you can secure both to a wall. You could I suppose turn them on their sides and stack them. Upright thay are quite high. Decent inexpensive rack.

I think not, as the tip of the unit is a bit wider than the sides...like a table top. I think it could be stacked, however, although i have not tried that. It would work well as two units side by side really.

I saw the following on the Fellows Webpage in there FAQs:"Can I get additional columns to make my monitor riser even taller?Unfortunately, no. Fellowes has tested the maximum height and weight distribution to ensure the safety of persons and equipment using this product.Additional risers are not recommended, as injury or equipment damage could result.We strongly discourage modifying the height over and above the original product design."
