Carrier DAMPSLB16X20 Slip-in Bottom Mount Damper

Product Description

The CARRIER DAMPSLB16X20 is a slip-in bottom mount zone damper designed for low-voltage HVAC zoning systems. Operating at 24 volts AC, it fits a 16-inch by 20-inch duct opening and delivers a 15-second blade travel time for responsive zone control. The damper installs directly into the duct from the bottom without sheet metal modification, making it a practical choice for service techs adding or replacing zone control components in residential or light commercial forced-air systems.

This damper is suited for use in ducted forced-air systems where individual zone temperature control is required. It is typically installed in branch or trunk ductwork serving a single zone, paired with a zone control board and low-voltage thermostat. The bottom-mount slip-in design reduces installation time compared to round-cut dampers, making it a common choice for retrofit zoning projects.

Key Features

• Slip-in bottom mount design for tool-free duct insertion without sheet metal cutting
• 24-volt AC control voltage compatible with standard zoning control boards
• 15-second blade travel time for smooth, responsive zone modulation
• 16-inch by 20-inch nominal duct opening size
• Carrier and Bryant compatible per manufacturer specification

Compatibility

Designed for use in Carrier and Bryant zoning systems. Confirm duct opening dimensions and control board low-voltage wiring requirements before installation.

Installation Notes

This damper is installed by licensed HVAC technicians as part of a zoning system. Power down the air handler and de-energize the zone control board before making any wiring connections. Secure the damper in the duct per the manufacturer instructions and verify blade operation through the full open-to-close cycle before restoring power. Follow local mechanical codes for duct penetration and sealing requirements.
