What are Y-Clips and why do you use them?

​Think about if you've ever showered with a shower curtain.
You want the shower curtain as close to the inside of the shower, that way water does not escape the shower. 
The concept is the same using a Y-Clip degree clip. We want to glass as close to the shower as possible to eliminate leakage.
Dependent on your tile, one of our sales professionals will tell you if it's recommended.
