ABSTRACT:
A seal for an enclosure of electrical equipment which is clamped between sealing surfaces on the enclosure base and the enclosure cover. The seal includes a cavity of a preferred hour-glass configuration and resiliently retains a resilient seal member of a preferred triangular configuration. The outer wall portions of the cavity permit expansion of the resilient seal member when the cover is forced against the base to provide a seal around the outer periphery of the enclosure.
