Lukjan SK01310100 Wall Stack 3-1/4 X 10 Buttonlock 2-piece

Product Description

The LUKJAN SK01310100 is a 100-inch section, 2-piece buttonlock wall stack measuring 3-1/4 x 10 inches. 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.

This 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.

Key Features

• 100-inch section length reduces the number of field joints in a single wall run
• 3-1/4 x 10-inch cross-section fits standard residential stud-bay cavities
• 2-piece buttonlock construction allows fast field assembly without separate fasteners
• Rectangular profile designed for low-profile vertical supply-air duct runs
• Compatible with standard wall stack boots, collars, and register fittings of matching size

Compatibility

Designed 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.

Installation Notes

Installation 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.
