Lukjan rx1010 Metal Tab Start Collar 10 Inches

Product Description

The LUKJAN rx1010 is a 10-inch metal tab start collar designed for round duct transitions in forced-air HVAC systems. Fabricated from galvanized steel, it features precision-formed tabs and a crimped connection edge that seat firmly against duct fittings to minimize air leakage at the transition point. The short profile makes it practical in tight plenum and trunk-line spaces where clearance is limited. HVAC contractors and sheet metal installers reach for this collar when building out supply or return duct systems that demand consistent, airtight connections. At 0.5 pounds, it is lightweight enough for single-hand positioning during install without sacrificing structural integrity.

The rx1010 fits 10-inch round duct and is suited for both residential and light commercial HVAC applications. Typical use cases include connecting round branch ducts to rectangular trunk lines, plenum boxes, or air handlers where a start collar is required. The crimped end accepts standard snap-lock or spiral round duct, allowing it to integrate smoothly into conventional duct layouts. Contractors working on new construction, renovation, or system retrofits will find this collar compatible with common round-duct runs in forced-air heating and cooling systems.

Key Features

• Galvanized steel construction resists corrosion in mechanical room and attic environments
• Precision-formed tabs provide a secure mechanical connection to duct openings
• Crimped end seats standard 10-inch round duct without additional forming
• Short collar profile fits confined plenum and trunk-line installations
• Lightweight at 0.5 pounds for easy single-hand positioning overhead or in tight spaces

Compatibility

Designed as an OEM-style replacement and standard-fit start collar for 10-inch round duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is typically performed by a licensed sheet metal mechanic or HVAC technician. Shut down and lock out the air handler or furnace before cutting into an existing plenum or trunk line. Secure the collar tabs against the duct opening with sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant to maintain system static pressure. Follow local mechanical codes and SMACNA duct construction standards for fastener spacing and sealing requirements.
