I thought I bought this side vent from R&M but it doesn't look like the ones they had at the snow show in SLC. Anyway I need to get it recovered. If anyone knows who makes them could let me know I'd appreciate it.
if all you need is new mesh and the frame is fine, rip out the rivets get some petproof screen, and rivet that stuff in. its the same as in most vent kits i have seen, like the exact same stuff.
He is right, pet proof screen is the same as outside material, I use it and it is $20 for 8 feet of the stuff. Enough to cover about 20 sleds. I use that and then some finer fiberglass door screen on the inside, keeps out small and large snow that way. Also coat it with wd-40 once a year and your good to go.
