A 12 spoke wagon wheel design with 2 spokes 'covered' by two bars creating a center badge. The 4 numbers and the foundry name, Campbell Foundry, Harrison N.J., are the only inscriptions. 8 straight vents circle the center. Unlike earlier variants the foundry name is not on the rim but on the middle of the three rings.
This type cover is often associated with parks, highways or NYC housing projects This is one of the rare examples of this type with 8 vents, needed at times to prevent the build-up of explosive sewer gases.
This type of cover is found throughout the city, often in parks or near housing projects. This one is south of LaSalle Street between Broadway and Amsterdam Ave.
