Joiner - Pregalvanised Metal

Metal duct joiner is a critical part used in connecting two pieces of duct that are of the same size, whether that be Flexible Duct or Solid Round Duct like Spiral Duct. 

Purpose/Function: The main purpose of a metal duct joiner is to create a secure connection between two duct sections, ensuring that air flows smoothly through the ductwork without leaks or disruptions.

Design/Installation: Joiners are made of  galvanized steel and in a cylindrical form with an opening at each end.  To install, simply fit the ducting over the joiner, taping, clamping, and use fasteners to hold in place for stability.

Support: Properly support the ducts to prevent joints from being pulled apart or damaged remembering that not only the duct core but also the insulation material (if present) needs securing. Duct tapes and Ductstraps can be used for this purpose.
