Abstract

An aerial closure for protecting an electrical or optical cable splice from weathering forces is provided. The aerial closure has a central header portion and wing-like housing segments that may enclose a cable splice. The wing-like housing segments may be raised, providing access to the cable splice from either side of the cable splice and below the cable splice. Each end of the aerial closure has a seal assembly for sealingly engaging the ends of the cable segments whereby the ends of the aerial closure are also protected from the weathering elements. The seal assembly has concentrically circular and corrugated features thereon so that an appropriately sized hole may be cut into the seal assembly for any standard cable size. The corrugated features allow marking the standard cable sized alternatingly on either side of the seal assembly so that it is easier to find and cut the correct sized hole for the cable. The housing segments may be locked with a simple latch, a nut and bolt assembly, or both. In the closed position, the bottom edges of the housing segments interlock for mechanical strength, but also have small spaces or cracks to allow any water to drain from the closure.
