The SEAL-TITE 1240-1810 is a rectangular short way duct elbow fabricated from 26-gauge galvanized metal, sized at 18 inches by 10 inches. It is designed for use in low-pressure supply and return air distribution systems and connects rectangular duct runs at 90-degree turns where space constraints require a short-radius elbow. The hemmed collar and mechanically seamed corner provide a rigid, leak-resistant joint. The engineered throat and radii geometry helps maintain consistent airflow through the turn. Licensed HVAC technicians and sheet metal contractors install this fitting as part of forced-air duct systems in residential and light commercial construction.
This elbow fits rectangular duct systems where an 18-inch by 10-inch short way configuration is required. It is commonly installed in attic runs, platform returns, and interior chase applications where duct routing must change direction within a limited footprint. The fitting meets CCR/Title 24 and IECC applicable standards, making it suitable for projects in jurisdictions that enforce those energy codes. The double-lapped, mechanically seamed corner and joint construction supports code-compliant duct fabrication practices.
Designed as an OEM-style rectangular duct fitting for 18-inch by 10-inch short way elbow applications in residential and light commercial forced-air duct systems.
Installation is performed by licensed HVAC technicians or journeyman sheet metal workers. Shut down and de-energize the air handling unit before making duct connections. Secure all joints with listed duct tape, mastic sealant, or mechanical fasteners per local mechanical code requirements. Verify that elbow orientation matches the short way dimension of the duct run before final attachment.
