1. A universal firestopping collar assembly for sealing about a panel penetrating member comprising:

  • A. a sealing member of firestopping material extending longitudinally and defining a plurality of frangible zones directly in the firestopping material of said sealing member extending partially laterally thereacross and spatially disposed from one another to facilitate sealing around panel penetrating members of various sizes and configurations, each of said frangible zones extending across said sealing member at spatially disposed positions to define longitudinally therebetween a plurality of individual removable member sections, said sealing member being breakable along any one of said frangible zones to remove at least one of said removable member sections in order to provide adjustment in the total longitudinal length of said sealing member to facilitate installation thereof in surrounding engagement with panel penetration members of various different sizes;

    B. a mounting strap of flexible material to facilitate urging of said sealing member into engaging abutment surrounding a panel penetrating member immediately adjacent a panel, said mounting strap including;

    (1) a compression surface with said sealing member secured with respect thereto and extending longitudinally therealong, said compression surface being positionable facing the panel penetrating member to facilitating urging of said sealing member in abutting contact thereagainst;

    (2) an outer surface located oppositely from said compression surface and facing outwardly away from the panel penetrating member responsive to positioning of said compression surface of said mounting strap facing the panel penetrating member for urging said sealing member into a surrounding position thereadjacent;

    (3) a securement edge positioned between said compression surface and said outer surface and extending longitudinally therealong;

    (4) a retaining edge positioned between said compression surface and said outer surface and extending therealong and being spatially disposed oppositely from said securement edge;

    (5) a plurality of securement tabs secured to said securement edge and extending outwardly therefrom, said securement tabs being attachable to the panel surrounding the panel penetrating member to facilitate holding of said sealing member into abutment with and surrounding the panel penetrating member;

    (6) a first end area including an engagement prong means extending outwardly therefrom, each of said engagement prong means being formed by stamping thereof from said first end area of said mounting strap, each of said engagement prong means being flexibly resilient and moveable relative to said first end area of said mounting strap, each of said engagement prong means being tapered and including a wider prong section immediately adjacent said mounting strap and attached directly thereto, each of said engagement prong means further including a narrower prong section integrally formed with said wider prong section and extending outwardly therefrom spatially disposed from the location of attachment of said wider prong section to said first end area of said mounting strap, the length direction of the engagement prong means being perpendicular to the length direction of the mounting strap; and

    (7) a second end area spatially disposed from said first end area along said mounting strap and defining a plurality of individual engagement aperture means therein positioned longitudinally therealong, each of said engagement aperture means being capable of receiving one of said engagement prong means extending thereinto for engagement therewith in order to selectively affix said first end area and said second end area together with said mounting strap extending around said sealing member in abutment with the panel penetrating member for biasing them together to facilitate sealing therearound, each of said engagement aperture means being positioned spatially disposed longitudinally with respect to one another along said second end area of said mounting strap to facilitate adjustability in sizing thereof to facilitate use of said mounting strap with panel penetrating members of various sizes and configurations, each of said engagement aperture means being tapered to define wider aperture end section and a narrower aperture end section contiguous with respect to one another to facilitate engagement thereof by one of said engagement prong means which are tapered, said narrower prong section being flexibly positionable extending into said wider aperture end section to facilitate entry of said engagement prong means into said engagement aperture means, said engagement prong means being flexible to position said wider prong section thereof into said narrower aperture end section for abutting engagement therebetween for facilitating engagement of said engagement prong means with respect to said engagement aperture means, the length direction of the engagement aperture means being perpendicular to the length direction of the mounting strap.
