Abstract
The present invention provides a transitional telescoping plenum apparatus that is intended to facilitate the interconnection of HVAC equipment to duct systems. The unit expands in length, width and height directions, and is composed of modular tier sections. Each modular tier includes at least four corner sections, with each corner section being interleaved with two adjacent corner sections to complete a single modular tier. Each modular tier includes a tier-connecting flange that communicates with a tier-connecting flange on another modular tier, such that the modular tiers can be interconnected to form a finished transitional telescoping plenum apparatus. Clips are also taught for connecting modular tiers to each other.
