Masterlock 44240-tpc Thermoplastic Duct Set 24in Set of 3

Product Description

The MASTERLOCK 44240-tpc is a set of three 24-inch thermoplastic duct components designed for HVAC air distribution applications. Thermoplastic construction provides resistance to moisture and temperature variation, making these components well suited for residential and light commercial duct systems. Licensed HVAC technicians and installers use this set when routing or terminating ductwork in room air or forced-air systems. The three-piece configuration allows for consistent, matched fittings within a single installation zone.

This set is intended for use in HVAC room air and forced-air duct systems. At 24 inches, these components fit standard duct runs in residential installations and light commercial buildouts. The set-of-three packaging reduces the need for separate sourcing when multiple matching fittings are required in the same project. Typical applications include supply or return air duct connections in split systems, package units, and air handler configurations.
