re: Oneida Supercell

Barb, you don’t need that kit. The generic green S&D pipe from HD or Lowe’s works perfectly fine. And the elbows that fit it are much less expensive. The pipe is easy to cut to size. I’d go with the Powertech aluminum blast gates. You can get them on Amazon. More expensive but much stronger and easier to keep clean. Use plastic plumbing tape to screw mount the pipe to the walls and press fit everything. Once you’re happy with it, get some proper duct tape (the metal stuff) and tape all your joints. Just my opinion, but kits usually end giving you several things you don’t need, and you pay for it. It’s more work to build your own system, but there’s less waste.
