"GlowRyder", the ultimate load backrest guard from J. McErins is made of high-impact polyethylene. Easy to install: simply cut to length, notch for cross bars, and snap/lock in place. "GlowRyder" snaps in place at the back of the rail and stays put. "GlowRyder" is a versatile load backrest guard system that is easily customized to your lifts. The 1” and the ½” extrusions can be abutted together to accommodate even those backrests that are made of both 1” and ½” flat bar. "GlowRyder's" O.S.H.A. fluorescent lime-yellow color dramatically increases the noticeability of your lifts for safer warehouse operation. Think about how much better your trucks will look, how much money you'll save on re-paint and decal work, and how much your insurance company and O.S.H.A. will appreciate the additional safety benefit.
