Jackel 18 in Solid Sump Pump Basin Lid. Solid sump basin cover is ideal for use with a submersible sump pump where a gas tight sump basin seal is not a concern. The corrosion proof single piece cover is injection molded structural foam polyethylene and provides superior structural toughness and reliability. The solid design allows for discharge and vent holes to be drilled in the field allowing for maximum flexibility. All fittings must be purchased separately.
