4” standard plastic chain is made with UV protectant added to retard fading and to maintain the integrity of the material. All our chain is guaranteed not to fade or become brittle for five years. The 4” standard plastic chain is manufactured from high density polyethylene and is formulated to contain no lead or phthalates, and it is recyclable. It has been used for several large light rail transit projects in the USA and Canada as it does not conduct electricity along railway tracks. It is also chosen for use in light rail projects because it is extremely strong and weather-resistant. More unusual uses have included mooring small paddle boats in marinas, and when paired with a rain gutter, it makes a decorative downspout replacement.
