Southwark Metal 105024 Beaded End Collar 24 Inch

Product Description

The SOUTHWARK METAL 105024 is a beaded end (B.E.) collar measuring 24 inches, used in sheet metal ductwork fabrication and installation. Beaded end collars provide a mechanical stop and a secure seating surface where duct sections connect to fittings, plenums, or equipment openings. The beaded edge adds rigidity to the collar end, helping maintain round shape during handling and installation. HVAC sheet metal contractors and duct fabricators install this fitting as part of low-pressure supply or return air distribution systems in residential and light commercial construction.

The 105024 collar is suited for round duct trunk runs, branch takeoffs, and equipment connections that require a 24-inch diameter collar with a beaded end finish. It is a standard shop or field fitting used when connecting round duct to air handlers, rooftop units, plenums, or duct transitions where a clean, reinforced collar seat is needed. The beaded end profile is compatible with standard snap-lock or spiral duct systems common in commercial and residential HVAC work.

Installation Notes

Installation is performed by licensed sheet metal workers or HVAC technicians following SMACNA duct construction standards. Power down all air-handling equipment before cutting into or modifying existing ductwork. Secure the collar with sheet metal screws and seal all joints with UL 181-rated mastic or tape per local mechanical code requirements. Do not overtighten fasteners on the beaded edge, as deformation of the bead can compromise the seal.
