The W2S series is a double door, channel framed access cover with 300 lb. psf (1464 kg psm) load rating. Units are supplied with spring assists and are ideal for casting into top slabs directly above equipment in vaults that do not have provisions for drainage. Please see the drawing page for standard features. The channel frame acts as a gutter to capture water run off and divert it away from the interior of the vault. Although the unit is not 100% water tight, it should be used when water intrusion is a determining factor.
