ABSTRACT:
An improved sidewall fitting is disclosed with a fitting body and one or more flanges disposed about the fitting body. Plaster catches disposed along a face of one flange and positioned approximately coextensively with the fitting body. The bodies of the plaster catches may be curvilinear-shaped, straight or concentric rings and the body portions may be of heights for aligned or off-setting configurations. The fitting is installed the plaster catches oriented directly below the body of the fitting, along a generally horizontal plane. Plaster is layered over the flange and plaster catches, and up to the opening in the fitting body. The plaster catches may be disposed along a posterior face of a flange, or simultaneously along the anterior and posterior faces. A second fitting type includes an extension surface for increased bonding with the plaster with additional surface area available for sealing with the plaster. Disposed onto the sealing surface is a leave-out strip, which protects the sealing surface during cementing. After removal of the leave-out strip, the sealing surface provides an uncontaminated surface on which a sealant may be liberally applied. Optionally, a seal may be provided on the sealing surface interposed between the leave-out strip.
