10" Stick On Collar

A 10‑inch stick‑on collar (also called adhesive take‑off collar) is a duct accessory used in HVAC systems to transition from a flat surface (plenum wall, ductboard, sheet metal) to a 10‑inch round duct (either rigid or flexible). It uses an adhesive (often in the form of a peel‑and‑stick gasket or pressure‑sensitive adhesive) on the flange to adhere to the mounting surface, creating a more airtight connection and reducing the need for (or augmenting) mechanical fasteners. These collars are ideal where ease of installation, sealing, and labor/time savings are desirable. Some models include features like dampers, scoops, or reinforcement ribs.
