Review for 1/4” X 1-1/2” X 48” UHMW polyethylene black plastic strip.This strip required a lot of clean up and edge deburring to make it useful. Badly warped. Not flat or straight at all. And badly scuffed on all sides.After I cut it to size and screwed it in place, it actually worked fine for my project. I knew it was McMaster but it was free shipping and that made it worth it.Width was +/- 0.1 over the full length.1 star for the condition of material. +1 star for length being oversized by about 1/2”.

This was clearly a production scrap from some other project. If it was actually UHMW polyethylene I wouldn't have been so disappointed, but it was just crappy acrylic plastic instead.
