The Base GB-500 Series 3/4” Tread supports heavy
foot and cart traffic – our most rugged and durable
tread. 3/4” aluminum framework assures dimensional
stability and longevity. A vinyl hinge allows
the tread to be rolled up and moved for under-tread
cleaning. A solid 1/8” thick vinyl “T” profile footer
runs the full width and length of each section and
provides a low-impact cushion for all traffic. See
page 11 for insert types and colors.
