Duct Support System

A lightweight, modular and adjustable duct support solution.

An adjustable roof mounting system that supports any type of ducting, pipework or fans, across many roof build-ups. Duct Supports that will withstand even the windiest conditions in Australia.

Our Duct Support systems are fixed using Monkeytoe clips and fixings that maintain the roof's structural integrity and ensure compliance with roofing warranties. 

As with all Monkeytoe products, loads are transferred back to the roof substructure through our premium roofing fixings. The Monkeytoe roofing clip ensures optimal roof protection with compatible materials and no debris traps.

Our Benefits
  • Reduce weight by 75% over alternative structural systems
  • High-tensile aluminium delivers longer spans - meaning fewer roof penetrations. 
  • Eliminate penetrations through the pan of the roof
  • Modular assembly
  • Fabricated from marine-grade aluminium
  • Modular assembly
  • Fabricated from marine-grade aluminium
  • Compatible with roofing warranties
