Abstract: A rectangular or square metallic frame defines an interior filter medium area. The structural frame member, or members, are channel-shaped in cross section with the channel opening toward the filter medium area. A slot is cut into one of the legs of the channel frame member at the juncture between that leg and the web of the channel, the slot being in general alignment with the interior surface of the channel web. A generally planar handle anchor plate extends through the slot and makes face to face contact with the interior surface of the channel web. A portion of the anchor plate protrudes laterally from the slot and pivotally carries a hand grip. The anchor plate is spot welded to the channel web.
