Snap-rite 04-309 Crimped Round Cap

Product Description

The SNAP-RITE 04-309 is a crimped round cap used in HVAC ductwork and sheet metal applications. The crimped end allows the cap to slip over or seat onto a round duct section, providing a secure, clean termination point. This type of fitting is a standard component in forced-air systems and ventilation assemblies. HVAC technicians and sheet metal contractors install this cap when terminating a round duct run or capping off an unused duct opening. Its round configuration and crimped construction make it a direct, no-modification fit for typical round duct connections.

The 04-309 is suited for residential and light commercial HVAC duct systems. It is used wherever a round duct end requires a finished, closed termination. The crimped design is compatible with standard round duct fitting assembly methods, allowing it to be seated and secured without special tooling. Sheet metal contractors and HVAC service technicians typically install this fitting during new system installation or when reconfiguring existing ductwork.

Key Features

• Crimped construction allows secure seating onto standard round duct ends
• Round cap configuration provides a clean, closed termination for duct runs
• Single-unit selling format for job-specific or replacement use
• Straightforward installation with standard sheet metal hand tools

Compatibility

Designed as an OEM-style replacement or new-install fitting for standard round duct termination applications in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Before installing or removing any duct cap, shut down the air handling system and confirm the duct section is depressurized. Use standard sheet metal hand tools for seating and securing the crimped fitting. Follow local mechanical codes and SMACNA duct construction standards where applicable.
