Wall stacks are rectangular sheet metal duct sections used to run supply air vertically inside wall cavities, connecting the floor boot to the register at the top of the wall. The buttonlock seam design allows the two halves to snap together in the field, reducing assembly time and maintaining a secure, rigid joint. HVAC installers use this type of component in residential forced-air systems where space constraints require a low-profile duct run inside a standard 2 x 4 or 2 x 6 stud bay.\u003c\/p\u003e\n\u003cp\u003eThis wall stack section is suited for residential heating and cooling applications where supply air must travel vertically through an interior or exterior wall cavity. The 3-1\/4 x 10-inch profile fits within standard stud-bay framing. The 100-inch section length covers a full wall run in many single-story installations, minimizing the number of joints required. It is typically installed by licensed HVAC contractors or sheet metal mechanics as part of a trunk-and-branch or radial duct system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-inch section length reduces the number of field joints in a single wall run\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 x 10-inch cross-section fits standard residential stud-bay cavities\u003c\/li\u003e\n  \u003cli\u003e2-piece buttonlock construction allows fast field assembly without separate fasteners\u003c\/li\u003e\n  \u003cli\u003eRectangular profile designed for low-profile vertical supply-air duct runs\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard wall stack boots, collars, and register fittings of matching size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction component for residential forced-air HVAC duct systems using 3-1\/4 x 10-inch wall stack fittings and boots.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC contractor or qualified sheet metal mechanic in accordance with applicable mechanical codes. Shut down the air handler and confirm the system is de-energized before connecting ductwork. Secure all joints with approved sheet metal screws and seal seams with listed duct mastic or foil-backed tape per local code requirements. Duct runs inside exterior wall cavities should be insulated as required by local energy codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSection Length\u003c\/strong\u003e: 100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Dimensions\u003c\/strong\u003e: 3-1\/4 x 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 2-Piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeam Type\u003c\/strong\u003e: Buttonlock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: HVAC Wall Stack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LUKJAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SK01310100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51306628317490,"sku":"SK01310100","price":45.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549136.jpg?v=1781293615","url":"https:\/\/voomisupply.com\/products\/lukjan-sk01310100-wall-stack-3-1-4-x-10-buttonlock-2-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
