Couple of small pieces of Lexan, screwed to endcaps (or maybe wood inserts), if I recall correctly. You'll also want the hose clamps on the arm when you put them on, because the screws also attached the guard strips.

I don't remember exactly what we used for those guard strips, but I want to say it was some sort of tile edging. Some of the more senior mentors will probably remember (or Shane will).
