Duct

12" Stick On Collar

A 12-inch stick-on collar is a circular duct fitting used to connect a round duct (often flexible duct or rigid spiral duct) to a flat surface such as a plenum wall, ductboard, sheet-metal trunk, or other duct surface. It “sticks on” to the surface, often via flanges, tabs, adhesive, or mechanical fasteners, forming a transition point (“take-off”) from the flat surface to a round duct run. Common uses: To create a “tap” on a ductboard or plenum for a branch run To connect flexible duct to a flat plenum or trunk wall As a starting point for new duct runs Often used behind registers or grilles, or within duct cabinets These collars may include additional features like a built-in damper (for flow regulation), adhesive or gasket sealing surfaces, or tabs for easier mounting.

It is designed for draft (negative pressure) applications and tolerates flue gas temperatures no more than about 400 °F above ambient. Hart & Cooley +1 The product line includes straight pipe segments, elbows, tees, adapters, storm collars, and caps to allow full venting runs. Installation is simplified by curled ends, locking bands, and modular fittings to maintain alignment and structural integrity

White Wide Flapper Sceen 11"

The BB-111381 vent hood is a wall-mounted, wide-mouth exhaust hood designed to terminate 4-inch duct runs (for dryer vents, attic fans, or general exhaust applications). It features a molded polypropylene (plastic) hood body with an aluminum trim / tailpipe. A built-in back-draft flapper prevents unwanted air or pests from entering when the system is off, and a snap-in pest grid (bird guard) protects against insects, rodents, and debris. The tailpipe is factory-installed and riveted, facilitating straightforward installation. The wide-mouth design helps reduce airflow restriction at the hood opening. It’s commonly used in residential ventilation systems to provide a low-cost, durable termination point for duct exhaust, while offering protection from backflow air and pest entry.

TYPE B - GAS VENT 90 Degree Elbow 4.5"

The Type B 90° elbow is a double‑wall venting component designed to change the direction of flue gas flow by 90° (a right angle) in a chimney / gas vent system for gas‑fired appliances (Category I, draft‑hood equipped). It is part of a “B‑Vent” (or “B gas vent”) system, which uses a concentric double‑wall pipe: an inner liner to carry the hot flue gases, and an outer shell with an insulating airspace to limit heat transfer to surrounding structure. A 4.5‑inch outer diameter variant suggests a nominal 4″ inner flue diameter. This elbow allows installing a right-angle turn in the vent run—for example, to route around obstacles, penetrate wall or ceiling offsets, or align with vent terminations. The elbow must maintain proper clearances to combustibles, be supported, and be compatible with the rest of the Type B system. In many installations, the elbow is adjustable (0°–90°) or comes with swivel or rotatable joint to facilitate alignment. It joins to other vent components via twist-lock, snap-lock, or locking tabs. One actual product, the Metalbest 4RV 90° Type B adjustable elbow, lists an outer diameter of 4.5 in and inner pipe (flue) diameter of 4 in.

TYPE B - GAS VENT 90 Degree Elbow 3.5"

A Type B 90° Elbow is a double‑wall vent fitting used in gas venting systems (also called B‑vent, B Gas Vent) to change the direction of exhaust flue gases by 90 degrees (a right angle). It is used where vent routing requires a turn—e.g. to avoid obstructions, align with wall penetrations, or change from vertical to horizontal or vice versa. Because it's a “Type B” component, it is meant for use with gas-fired appliances (e.g. gas furnaces, boilers, water heaters) under certain temperature and pressure conditions (Category I type appliances). It’s not for use with wood or high‑temperature exhausts (unless explicitly rated). The elbow is prefabricated (rigid) or adjustable (telescoping / articulated) so you can set the angle precisely. It maintains the proper clearances to combustibles and ensures safe venting of combustion gases through the proper inner liner, while the outer wall protects the structure from heat. For your “3.5‑inch diameter” case, that might refer to the outside outer shell (outer wall) dimension, while the inner flue might be nominal 3" (common in B‑vent systems). For example, I found a 3” Type B 90° elbow listing which states an outside diameter of ~3.5".

8x14x10 Ceiling Box

The Southwark 51F81410 / RB81410 is a straight ceiling box with flange designed for HVAC duct transition from a ceiling or plenum surface. It provides a mounting box and collar interface, enabling a round duct (in this case 10‑inch diameter) to connect into a ceiling or flat surface in a structured, sealed way. The box is built from steel and finished with hot‑dipped galvanization for corrosion resistance, making it suitable for indoor HVAC environments. Its flange allows you to fasten or seal it against a ceiling surface or ductboard, while the collar section extends into the ductwork system to accept round duct. It is intended for a 10-in duct collar, so it serves as a junction point in ventilation systems.

collar 7''

A snap collar (also called snap‑lock collar, starting collar, or ductboard snap collar) is a circular duct accessory used in HVAC systems. It is designed to be snapped together (i.e. the shell folds or latches) to form a rigid collar that fits into or onto a ductboard, plenum, or flat surface. Once snapped, it provides a connection point for round ductwork (in this case, 7‑inch diameter ducts). The “snap” mechanism allows for faster installation without welding or extensive mechanical fastening. Snap collars are used to transition from flat surfaces (ductboard, sheet metal, plenums) to round duct, for supply or return branches, and they help maintain airflow integrity and structural support.

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.

8" Stick On Collar

An 8‑inch stick‑on collar (also called adhesive or press‑on collar / takeoff collar) is a duct accessory used to connect a round 8‑inch duct (rigid or flexible) to a flat surface (plenum, ductboard, sheet metal) with minimal mechanical fastening. Unlike snap collars or starting collars that require screws, rivets, or snap tabs, a stick‑on collar uses a built‑in adhesive gasket or pressure‑sensitive adhesive (PSA) on its flange to “stick” to the mounting surface, forming an initial seal. It is designed for HVAC applications (supply or return branches) where ease of installation, reduced air leakage, and labor/time savings are prioritized. Some models include extras like scoops, dampers, or pre‑crimped edges to facilitate duct connection.

4" Stick On Collar

A 4-inch stick-on collar is a round duct connector designed to be attached to flat surfaces (such as rectangular duct plenums, ductboard, or sheet metal trunks) without requiring screws or rivets for initial placement. Instead, it uses a self-adhesive flange or gasket to "stick" securely to the mounting surface. Once attached, it serves as a transition point between the main duct or plenum and a 4-inch round branch duct, allowing the connection of flexible or rigid round ducts for air distribution. Stick-on collars are used in HVAC systems for both supply and return air applications and are valued for easy installation, improved sealing, and labor savings.

collar 4"

A 4-inch snap collar is a circular fitting designed to be mounted onto ducts, pipes, or walls to create a clean, secure transition point for round ducts or flex pipes. The "4-inch" refers to the inner diameter of the collar, which matches standard 4-inch ducting. It typically features a snap-in flange that locks into place, making it easy to install without screws or welding. It can be used for ventilation systems, dryer exhausts, HVAC applications, or dust collection systems.

TYPE B - GAS VENT Top 4" Round

A Type B gas vent cap (also called a rain cap, vent top, flue cap) is a fitting installed at the top termination of a Type B (B‑vent) gas vent system. Its purpose is to: Prevent rain, snow, debris, and animals from entering the vent pipe Provide a safe termination for combustion gases to exit the vent system Allow gases to be expelled safely while maintaining draft Protect the venting system from external elements and ensure compliance with codes This cap is specifically meant for Category I gas appliances that use a Type B venting system, which is a double-wall, air-cooled metal vent system for gas furnaces, water heaters, boilers, etc.

RETURN Plenum Supply 16.5x17x24 - No Insulation

It's a supply plenum or duct plenum created by CEN Fabrications. The plenum is a box‑shaped sheet metal piece used in HVAC systems to connect an air handler, furnace, or coil outlet to the ductwork, distributing conditioned air into the ducts. The dimensions 16.5″ width × 17″ height × 24″ depth indicate a relatively compact plenum, probably used where space is tight (e.g. compact utility closet or small air handler). Likely uninsulated, unless otherwise specified, since many plenums are built without insulation unless required (for noise, thermal control, condensation prevention). Probably involves standard galvanized steel (galv. sheet metal) construction by CEN, with seams, flanges or collars for connection to ducts.
