EBW SAFE-LITE FRC manway covers are ultra lightweight. Engineered and tested to exceed the D.O.T. H20 load ratings. Covers weigh almost one-third less than steel, which dramatically reduces injury potential during cover removal. Available in 12", 30", 36", and 42" sizes. The slide action cover further reduces the chance of injury by eliminating the need to bend down to remove or replace the cover.
