Duct Fast Clamps - 200mm

200mm Fast Clamps - Pack of 2.
Used to quickly and securely clamp spiral ducting to fans so the fans can be removed for testing/cleaning without dismantling the ducting.

Fast clamps are mostly used for installation of round duct fans. The clamps are lined with polyurethane foam on the inside. First, the clamp is slid over the end of a SPIRAL duct; the duct fan port is aligned with the Spiral duct, leaving a small gap between the two parts.

Finally, the fastening clamp is slid over the duct fan port and tightened.

Once tightened, the fastening clamp provides an airtight and fast connection; if the duct fan fails or requires off-site servicing, the fastening clamp can be easily removed to enable disassembly.

The fastening clamps are delivered flat and need to be bent around the duct exterior.
