Introduction: The AFX Armco Barriers are a natural evolution from the classic Guard Rails and connect seamlessly with Brand New Catch Fencing. Though HO scale slot cars create significantly less force or risk of damage, these Armco Barriers play an integral role in protecting your slot cars. Its intricate design is strong yet bendable. Shape it to any curve in your track layout for secure, reliable connections. The best part is the space added between the edge of the track and the barrier. This “wiggle room” gives your cars more play on curves so your car corners better than ever before.
