Abstract

A device for the support of ceramic catalyst monoliths especially of square cross section as well as for the combination of several of such monoliths into one package. It is formed of an elastic gasket attached on one or both monolith ends and a metal frame attached on the gasket under pressure. The frame has recesses on two adjacent lateral surfaces, and at the two opposite lateral surfaces it has projections which can engage interlockingly into the recesses of adjacent frames.
