Surly Track CogsSURLY TRACK COGS Our track cogs are designed to spin onto standard ISO threaded (1. 375" x 24tpi) hubs, so they will work with most English, Italian and Japanese hubs, including the Surly New track hubs.

These are easy to put together and to use. We have used them with all the panels. We have also used them broke down into 2 and 3 panels. They work well for blocking views. They don't block noise or help quiet the room being used, however. Only bad thing about them. We use them for our Auxiliary meetings.

Easy to assemble. Still used for over a year 🙌🏾

Color: White, Size: 6 Panel

Everything is perfect! I would buy again in other colors and heights if I need additional separation in the basement.

Cheap Garbage

Color: Black, Size: 4 Panel

This item is just cheap crap. Shoddily put together, shoddy materials, and looks cheap. If you’re just putting it in a space that you don’t really care that it’s cheap, then it might be fine for what you need. But don’t expect much.

Keeps areas separated

Color: Black, Size: 6 Panel

Item arrived quickly. I use this to keep my cats out of a part of the cellar. Works great. They've figured out how to slip through side. I made a panel that covers those spots. Still the best item to keep area separate.
