Decor Grates AJH410-NKL Oriental Floor Register, 4x10 Inches, Brushed Nickel Finish

I bought a 4-pk of 4"x10" floor registers because they were much cheaper to buy in multiples, and I need 5 of this size. Unfortunately, I'm still waiting on the extra (more expensive) one. These are quite red in direct sunlight, almost copper looking, but they're perfect in indirect/artificial light with our brown-stain hardwoods. I like the open/close mechanism a lot; 2 sheets of perforated plastic slide over each other to align or overlap the slits. This seems much more reliable than the metal flaps on other vents, which can catch on carpet or rough opening edges. The tab for the mechanism looks a little flimsy, but I probably only adjust vents, at most, twice a year (with the seasons), so I'll just be careful!
