These versatile covers can be used as side guide rails, support members under belting and table top chains, cable guides, and lane dividers. Since the introduction of stainless steel guide rails in the 1980s, Spiratex has been providing guide rails where the ULTREXTM UHMW/PE insert completely fills the 304 stainless steel sheath. The solid design eliminates the gap between the insert legs and steel sheath, which prevents dirt and bacteria collection. Custom ULTREXTM UHMW/PE materials including gray lubricated, enhanced conductivity, anti-static and high temp are available upon request.
