End cap for 10-325?

I just installed the 10-325 shower sweep with drip rail and noticed that on the left end (NOT the side closest to the actual shower but the side that actually swings out when the door is open) the metal could potentially be a hazard if one were to hit it hard.

Do you suggest putting some kind of plastic end cap on that side so that it?s smoother and wouldn?t hurt someone if they were to accidently hit it?

If so, do you sell and end cap that fits the 10-325 shower sweep? Thanks.

Thank you.
