I compared this with another Moen rod, DN2160CH, and decided to get this one. CSR2165CH is a fixed-length rod, perfect for my shower enclosure. DN2160CH, which is adjustable, is a two-piece overlapping tube, and the inevitable "seam" was the deal-breaker.
This was very easy to install, once I found out that the recommended 1/4" drill bit is exactly what I needed for drilling holes on the tile. I got the specialty drill bit for tile and glass with carbide tip from Lowes, and it worked beautifully.
I'm very pleased with the finished product!
