Patent ID: 7297009

Claim:
An insulating kit for providing a barrier through which cables are channeled from one room to another room, said kit comprising: a trim plate including a plurality of rigid sections contiguously arranged end-to-end and spanning across a floor surface such that said rigid sections define a cavity within an inner perimeter of said rigid sections, each of said rigid sections having corresponding beveled edges outwardly sloping away from associated ones of said inner perimeters; a core member having a single and unitary body formed from deformably resilient material, said core member being centrally registered between said rigid sections and disposed beneath the floor surface; and a plurality of mounting flanges symmetrically aligned along said inner perimeters of said trim plate and directly abutting said outer perimeter of said core member, each of said mounting flanges being provided with a plurality of monolithically formed ribs inwardly protruding into said core member; wherein a plurality of computer cables are removably passed through said core member and thereby causing said core member to laterally expand against said mounting flanges and constrict air gaps created within said core member when the computer cables are passed below the floor surface and into said core member.
