Radial Duct Cutting Tool for 75mm & 90mm Semi-Rigid Ducting

Description

The Casavent LIN/898603 Radial Duct Cutting Tool is a purpose-built cutter for trimming semi-rigid radial ducting to length on site. Designed around the corrugated profile of the duct wall, it produces a clean, square cut without crushing or deforming the bore, so the cut end seats properly in a flange, connector, or plenum spigot.

Cutting semi-rigid HDPE duct with a standard utility knife is possible, but a dedicated cutter gives a straighter, more repeatable cut — particularly useful on larger installations with many duct lengths to trim to size.

Installation Tool This is a hand tool used during installation — it does not include the duct itself, which is sold separately.

Clean, Square Cuts The cutter is shaped to follow the corrugated duct profile, producing a straight, square-edged cut rather than the ragged or angled edge a utility knife can leave, which helps the duct seat correctly in its connector.	Reduces Installation Time On a project with many duct runs to cut to length, a dedicated cutter speeds up the job compared to repeated knife cuts, especially where consistent cut quality matters for airtightness.
Protects the Duct Bore A clean cut avoids crushing or distorting the duct wall at the cut end, which could otherwise compromise the seal where the duct meets a flange, coupling sleeve, or plenum spigot.	Sized for the Radial Duct Range Matched to the 75mm and 90mm semi-rigid radial duct diameters used throughout the Casavent radial MVHR/MEV system.
Reusable Site Tool As a durable hand tool rather than a consumable, it is intended for repeated use across an installation or between projects.

What is this tool used for?

It is a hand-held cutter for trimming Casavent 75mm and 90mm semi-rigid radial ducting to length on site.

Why not just use a utility knife?

A utility knife can cut the duct, but a purpose-built cutter gives a straighter, more repeatable square cut that seats more reliably in flanges, couplings, and plenum spigots — useful on installations with many cuts to make.

Does this tool cut both 75mm and 90mm duct?

It is intended for use across the 75mm and 90mm sizes in the radial duct range. Confirm exact compatibility with the supplier if working exclusively with 90mm duct.

Is this a consumable or a reusable tool?

It is a reusable hand tool intended for repeated use across an installation or between projects, not a single-use item.
