Patent attributes
A kit includes a trim plate that has rigid sections arranged end-to-end, defining a cavity within an inner perimeter thereof. Each section has a corresponding beveled edge outwardly sloping away from the inner perimeter. A core member has a unitary body formed from deformably resilient material and is registered between the rigid sections, beneath the floor surface. Mounting flanges are aligned along the inner perimeter of the trim plate and abuts the outer perimeter of the core member. Each mounting flange has ribs that inwardly protrude into the core member and extend along an entire length thereof. The ribs are coupled with the core member so that same is prohibited from downwardly traveling beneath the floor surface. Computer cables pass through the core member, causing same to expand against the mounting flanges and constrict air gaps created within the core member when the cables are passed below the floor surface.
