This patent describes a frame adapted to surround and sealably support a generally rectangular filter pack or the like and which comprises four separate side panels which are interconnected in an end to end, rectangular arrangement. In the improvement described here the adjacent end edges of adjacent side panels are effectively sealed along their interface and: each of the separate side panels of the frame includes opposite side edges extending in the lengthwise direction, opposite end edges, inner and outer faces, and at least one pair of channel forming means overlying the outer face of the panel and extending in the lengthwise direction and cooperating with the outer face of the panel to define a lengthwise extending slot between the pair of channel forming means, and with the slot of each side panel communicating in right angles relationship with the slots of the adjacent side panels, and at least one corner plate interconnecting each of the adjacent end edges of adjacent side panels, with each of the corner plates comprising a pair of flanges disposed at right angles to each other in cross section and so as to define a bight at the intersection of the flanges, and a recess formed in such corner plate which extends along substantially the entire length of the bight and continuously along at least the medial portion thereof, with the recess having a sealing material therein, and with the flanges being closely received within respective ones of the slots of the associated side panels to interlock the corners and such that the sealing material serves to seal the adjacent end edges of the adjacent side panels.
