works great
Bombproof. I had buried my initial vault too deep by several inches. I dug around the old vault and simply placed the extension upon the old vault. easy

Great Quality!
I bought this box riser to correct for uneven terrain at the main water shut off. It fit perfectly and I completed the job in less than 10 minutes.

Absolutely perfect fit atop my NDS valve control box
I bought 2 of these. I have 2 existing buried valve control boxes that are somewhat even with their tops at ground level. They're both in line with my bushes so, the wood chips used by the HOA landscapers cover several inches over the lids of both of the valve control boxes. The get the tops above ground again, I removed the current NDS cover lids, placed these extensions over the in-ground boxes, and then applied my cover lids atop these extensions. Now, when they come to apply the landscaping wood chips, I'll have a few inches left that won't be burying the tops of these. There's about a 3/4-inch overlapping "lip" that makes these fit atop the valve control boxes so well. They don't quite "snap" on but they're snug enough to hold their fit once the surrounding soil and wood chips are reapplied around them. These were a perfect solution.

NDS-113 box extention worked well
The NDS-113-6 Standard Valve Box Extension worked eactly as expected - made the NDS-113 box 6 inched taller. Fit nicely. Might have been nice if there was a way to bolt the two together, but not necessary once buried.

This valve box extension did what it was supposed to do. It would be helpful if there was hardware included to attach to the base valve box.

I have added a back flow valve and I need the height to make it work. Local store does not carry the extension.

Water line access was too deep for standard 12in valve box, I wanted it above the dirt line

wanted a tall one, this will extend the basic NDS box

Using with bricks under it - instead of full depth box

I had installed a standard valve box near a driveway and had increased grade around the original install necessitating use of this extension.

Can you stack multiple extensions in order to reach the height needed?

how does nds-113-6 attach to nds-113bc. does it just sit on top or is it anchord together?
A shopper on Mar 22, 2014
BEST ANSWER: The nds-113-6 extension has a lip around its bottom that fits precisely on top of the nds-113bc. No further attachment is necessary.
looking for a 24 1/4 x 17 3/4 valve box extension ?
sam d on Oct 3, 2018
BEST ANSWER: My order of the 14 x 19 x 6 worked great, I didn't need to order the lid with it, the existing lid worked fine.
I have an older Armor Control Box Box. Cover seems to match this NDS 113-6 extension. (within 1/8th")

DO you think this can work?
David A on Jun 18, 2013
BEST ANSWER: I am not familiar with the Armor company. I used the NDS as intended on an NDS box. If your dimensions are within the 1/8th" and using it as an extension it should slip over your box as long as there are no obstructions around the outside perimeter of the box and the shape is the same.

Hope this is helpful information
which valve box extention for Ametek 3858755?
A shopper on Apr 27, 2013
BEST ANSWER: Sorry, I don't know if I can help. The one I have is an NDS brand so I figured this extension would fit. I did go to the spec page and compare all the measurements just to be sure and it fit perfect.
This company also sent the extension out immediately, I had it within a couple of days.
Does this fit on top of a water meter box outside at the street to make it be higher so water does not fill the meter box when it rains? Please advise

how does a nds- 113-6 extension and a nds-113bc attach together? are there any shorter extensions than a 6 inch?
carl m on Mar 22, 2014
BEST ANSWER: This is the only extension height for a NDS-113bc box (14"x19"x12"), it just slips on top of the 12" box and gives about 5 1/2" of extension worked great for my valves at 18" deep (you can check the NDS website to see if they have added any additional heights). If you need a shorter extension try putting paver bricks under the regular box as the brick is 2 1/2" high and will not rot.
