TEMPORARY GRATE COVER ESPECIALLY ADAPTED FOR PAINT SPRAY BOOTH AREAS

摘要

An improved cover for a paint spray area grate having parallel grate blades and parallel grate cross members is disclosed. The cover is provided with built-in protuberances in skirt members which lock or clamp the cover to grate cross members and with skirts which extend below the lower edge of the grate blades, thereby providing certain advantages over prior art structures which are not characterized by such structure.
