Clear Shower Door Bottom Rail and Wipe Seal For 3/8" Glass- 95" Long

Moved into a new house with a frameless glass shower. Used this product on the hinge side of the door. Works great! The best way to cut this to length is a miter box and hacksaw. Clean up the end with a razor knife.

It's the perfect configuration but it said it is easy to cut and I can't seem to cut it without shattering the more rigid part, so it's still propped against the wall. My first attempt looks awful.
