I'm helping out a cousin in his quest to make his living room into a working home theater that also satisfies his wife sense of decorum. He's got powered blackout blinds, but they still leak light around the edges. I knew a guy who had a similar problem and solved it by using the covers for raceway conduits as tracks around the sides of the blinds. So we went off to home depot and loews in search of something similar, but the only raceway conduits they seem to carry are low-profile ones. We need something that is at least 3/4" deep in order to effectively keep the blinds on track and block any light leakage.

We found some stuff online, like this one:
But it would be nice to find a local source so we can easily experiment with different dimensions and check the opacity of the material.

Any suggestions for other stores that might carry the stuff? If it matters, my cousin lives in the san fernando valley.

Panduit makes a big variety of duct and duct covers too

I had the same issue:

at Home Depot I found vinyl edging that is used for vinyl siding trim: the bar code ends in 37170 and is available in different sizes: it is L shaped

the nailer portion, which is wider, is affixed to sides of tracks and the return edge helps reduce any light leakage; it is not perfect but it helps

please take the high road in every post:do not respond to or quote a problematic post: report it a mess this is a red flag issue

Would a track made from wood trim be an option? 3/4" square dowel?

I believe Home Depot carries U-shaped aluminum extrusions in the bins with the angle iron and flat steel. You might find a size that would work.
