Pitch pocket

Abstract

An enclosure assembly for use with mechanical penetrations through a roof including a plurality of structural sections. Each structural section has a vertical portion, including a first end and a second end, and a horizontal portion. Each first end includes projections and each second end includes receptacles, wherein each projection is adapted to sealingly engage with a receptacle of an adjacent structural section. Each projection is inserted into a cooperatively aligned receptacle of an adjacent structural section to form a polygonal-shaped assembly having a plurality of connections and defining a cavity. The projections may be hook-shaped and the receptacles may be rectangular-shaped. The resulting cavity is shaped to contain a sealing material suitable to sealingly enclose a mechanical penetration and a portion of the exterior roof surface within the cavity.

What is claimed is:  
     
         1 . A pitch pocket assembly for use with mechanical penetrations through a roof, comprising: 
 a plurality of structural sections, each structural section having a vertical portion and a horizontal portion, each of said vertical portions comprising a first end and a second end;    each of said first ends comprising at least one projection and each of said second ends comprising at least one receptacle, wherein each of said projections is adapted to sealingly engage a said receptacle of an adjoining structural section;    wherein each of said first end projections is inserted into a cooperatively aligned second end receptacle of an adjoining structural section, thereby forming a polygonal-shaped assembly, said assembly having a plurality of connections between adjoining vertical sections and defining a cavity formed by a plurality of said vertical portions and an external roof surface.    
     
     
         2 . The assembly according to  claim 1  wherein said projections are hook-shaped and said receptacles are rectangular-shaped, wherein said hook-shaped projections insertable engage said rectangular-shaped receptacles to form an essentially fluid-tight connection between adjoining vertical sections.  
     
     
         3 . The assembly according to  claim 1  wherein said cavity is adapted to contain an amount of sealing material suitable to sealingly enclose a portion of a roof penetration disposed within said cavity and a portion of the exterior roof surface disposed within said cavity.
