We did this job a few months back in Fort Collins. The customer kicked around the idea of doing either u-channel or glass clamps for a while, but ultimately decided on clamps. The tile was very level, so this turned out very nice! The hardware was all brushed nickel and included beveled clamps. We actually got a thank you note from the owners after this install which was great!
Just caulking the interior with a mold resistant silicone in this picture.
