Abstract: A terminator fitting useful for connecting corrugated tubing to an electrical outlet box and including a cylindrical collar having first and second ends and a rib projecting radially inwardly from the collar for engaging an external rib on corrugated tubing placed within the collar. The collar carries circumferentially-spaced, axially projecting projections on one of its ends, with each such projection including a wedge-shaped free end portion. Each wedge-shaped end portion is joined to the first end of the collar by a web portion. The web portion, free end portion and collar define a groove for engaging the side wall of an outlet box when the arcuate projections are forced through an opening in the box to secure the fitting in the box. A plurality of blocking flanges are included in the terminator fitting with each blocking flange extending in a circumferential direction from a lateral edge of one of the wedge-shaped free end portions.

Abstract: A multiple channel duct manifold system for optical fibers which includes a plurality of elongated, corrugated tubing sections extended in parallel, contiguous relation to each other, and retained in such contiguous relation by a surrounding overwrap of thin flexible, synthetic resin film.

Abstract: A system of flexible conduit and fittings useful particularly, though not exclusively, for conveying, supporting and connecting electrical service cables and wires. The system includes a corrugated, synthetic resin conduit which is flexible and mechanically strong, connector sleeves for clampingly engaging sections of the corrugated conduit in end-to-end relation, and hanger sleeves for clampingly engaging the conduit and suspending it from a wall or similar surface. A novel electrical outlet box is provided and includes internally toothed conduit-receiving inlet fittings for securely engaging an end of the conduits in inlets to the box.

Abstract: A wall drainage system for protecting foundations and basement walls from water contact and seepage and including a water-impermeable synthetic resin backing plate adapted for securement to a surface to be protected and defining drainage channels along one side thereof facilitating drainage of water downwardly along the backing plate through the channels. A water-permeable synthetic resin strainer film is secured to the backing plate across the drainage channels. A synthetic resin water-receiving footer structure is connected to the lower end of the backing plate and includes a foraminous, synthetic resin bead pack and a perforated drainage pipe at least partially surrounded by the bead pack.
