100mm DUCTING CLAMP

Description

100mm Ducting Clamp

Securing a duct connection

The 100mm Ducting Clamp holds matching-size ducting around a compatible fan outlet, inlet or duct fitting. The original product illustration shows a metal band with an adjustable screw mechanism. It is a connection accessory for a ventilation system, rather than a fan, duct section or structural mounting bracket.

Choose the clamp around the connection you intend to make. The listed 100mm size describes the nominal duct application. Check the actual duct and mating collar together, including the material that will sit under the band, before selecting fittings for a new arrangement.

100mm Ducting Clamp selection details

Use this clamp with a compatible 100mm duct connection. Keep the band positioned over the joined duct and collar so tightening acts on the connection. Check that it can sit evenly without being obstructed by a flange edge, nearby bracket or the screw housing of another clamp.

The product photograph shows how the band and screw housing are arranged. It does not establish an exact minimum-to-maximum adjustment range, band width, tightening torque or stainless-steel grade. If your installation depends on one of those specifications, confirm it before ordering.

Planning the number of connections

Count the individual duct ends that need to be secured. A single duct length joined to equipment at both ends normally creates two separately clamped connections. Two separate duct lengths can create four connections, depending on how the fan, filter, fittings and outlet are arranged.

This is a planning example, not a statement about pack contents. Identify the joins on a simple sketch before ordering accessories. Include both sides of a reducer or joiner where each side uses a clamped duct connection, and check whether the equipment already supplies its own fixing method.

Preparing the duct and collar

Before fitting the 100mm Ducting Clamp, check that the mating connection is appropriate for the duct material and size. Position the duct over the collar according to the duct or equipment instructions. Keep the connection accessible so the band can be inspected as it is tightened.

Arrange the duct route before securing the final position. A sharp bend immediately beside the collar can pull the duct away from the connection. Support longer or heavier sections independently instead of using a clamp to carry the weight of a fan, filter or hanging duct assembly.

Using the screw-band adjustment

The screw mechanism adjusts the band around the connection. Use a tool that fits the actual screw head and tighten according to the equipment and duct instructions. Aim for a secure connection without crushing a plastic collar, cutting the duct wall or deforming the mating component.

A larger tightening force is not automatically a better result. Check how the duct sits under the band, especially where flexible material can fold. If the band cannot sit properly, review the fit and connection arrangement rather than compensating for a size mismatch by tightening further.

Checking the 100mm Ducting Clamp

Once the ventilation system is assembled, inspect each connection for movement or an obvious gap. Recheck the duct route after positioning the fan or filter because moving equipment can place new strain on a previously secure join. Keep the screw housing reachable for later inspection.

A clamp secures the mechanical connection; it does not by itself establish an airtightness rating for every duct material and fitting. Follow the relevant installation instructions if the system also requires a suitable sealing method. The chosen method should be compatible with the duct and equipment.

Comparing ventilation accessories

Choose the 100mm Ducting Clamp by the connection it needs to secure, then check the remaining duct route. Different fan, filter or fitting diameters may require adapters and different clamps at their respective ends. Do not assume a nominal 100mm clamp suits a 125mm or 150mm connection.

Keep your duct and equipment model details available when comparing accessories. Contact Hunter Hydro for help with your connection layout. The supplier’s 100mm clamp listing provides a related size reference; confirm any material or adjustment-range requirement for the stock you need.
