ABSTRACT:
A resilient gasket seals a connection between a wallplate rim and a wall, and is formed in situ by locating an insert on the backside of the wallplate inside of the rim and then introducing a flowable gasket material therebetween. The insert serves as a temporary dam during the in situ formation of the resilient gasket and is adapted to be removed from the wallplate prior to mounting to the wall. The insert extends above the wallplate rim, thereby protecting the resilient gasket during shipping, and also enabling vertical stacking of the wallplates prior to curing of the flowable gasket material. Use of this insert reduces the manufacturing time and labor costs in forming such wallplates.
