Round Duct Bracket AWENTA KO100-28 for 100 mm ventilation duct

AWENTA KO100-28 is a mounting bracket designed for 100 mm round ventilation duct. The bracket secures circular ducting to walls or ceilings, providing stable mechanical support for HVAC installations in residential and light commercial environments. It helps maintain duct alignment along runs and reduces movement or sagging by offering a fixed anchoring point for each section of round duct.

Advantages

The bracket is shaped to fit 100 mm round ducts precisely, enabling quick and accurate positioning during installation. Constructed from corrosion-resistant metal with a simple fastening layout, it delivers steady load-bearing capacity and long-term reliability in typical indoor ventilation conditions. Its compact form factor minimizes visual impact while allowing straightforward attachment to a variety of mounting surfaces.

Suitable for

• Securing 100 mm circular ventilation ducts to walls
• Mounting round ducts to ceilings or soffits
• Residential and light commercial HVAC runs
• Repairing or reinforcing existing ductwork support points

Key specifications

• Designed for round ventilation duct with 100 mm nominal diameter
• Material: corrosion-resistant metal suitable for indoor HVAC use
• Bracket profile: supports full circumference contact for stable hold
• Mounting method: screw/bolt attachment to structural surfaces
• Finish: protective coating to reduce oxidation in indoor environments

How to use

Position the bracket so the duct rests evenly within the curved support. Mark mounting points on the wall or ceiling through the bracket holes, then drill and fix the bracket using appropriate screws or anchors for the substrate. Place the 100 mm round duct into the bracket and secure it with screws, clamps or self-tapping fasteners as compatible with the duct material. Check alignment along the duct run and add additional brackets at regular intervals to prevent sagging and to maintain airtight joints where required.

Usage recommendations

Use suitable fasteners for the mounting surface (masonry anchors for concrete, wood screws for timber studs). Space brackets at intervals recommended for 100 mm ductwork—commonly every 1–1.5 metres—or more frequently where the duct carries additional loads or runs horizontally. Inspect bracket fixings after installation and during periodic maintenance to ensure continued support and alignment.
