Great product and great price!
After figuring out the previous owners had only installed a 6 inch riser i decided to increase the height and replace our damaged lid. Luckily this was the same product as what was allready there and a direct replacement. Installation was as easy as placing the new riser on top of the old one and screwing it into place. The lid fit perfectly and has a rubber gasket for a good seal. No more digging 2 and a half feet to get to my lid!

Worked as well I I hoped!
These are stackable, and qty 4 Allowed me to create two 24โ deep access portals to my septic tank. I recently installed an aerator so having Easy access to the tank to monitor this system was my aim. I only installed 12โ and the lids in the beginning and finally decided to add more dirt to level off my yard so I added 2 more 12โ to the existing risers. I was pleasantly surprised that the stacking/nesting seal at the joint works as well as tight as the lid seal, and mounting ring seal. I bolted this to tank and everyone says Bhutl tape was the way to go but I found it hard to work with, and ultimately a failure. (Installer issue Iโm sure) I just sealed it up it โgreat stuffโ Expansion foamโ weโll see in a year or so if that w a mistake- it looks good now, but itโs only been 60 days

Easy in install.
The shrink wrap distorted the shape of the riser but after a day or so the out of round shape is ok. Easy to install - use #10 x 1 1/2 inch stainless steel screws. The riser sections do not have an o-ring gasket but the lid does. Lightweight but very sturdy.

I'm glad I bought this septic risers instead of the other options available on Amazon, this were super easy to install and are super sturdy. I bought 4 riser sections 2 lids and 2 adapters the price wasn't the best but I think I got what I paid for QUALITY.
