SpiroFlex clamp for duct connectors 210 mm diameter SX-OKD210OBO

The SpiroFlex clamp for duct connectors 210 mm diameter SX-OKD210OBO is a metallic fastening band designed to secure circular ventilation and extraction duct sections and accessories with a 210 mm nominal diameter. It is intended for mechanical joining of connectors, sleeves and fittings in HVAC and extraction systems where a sturdy metal clamp is required to hold components in place and ensure a stable joint.

Advantages

This clamp provides reliable mechanical fixation for circular ducts and connectors, reducing movement and maintaining alignment at joints. Constructed from metal suitable for typical ventilation environments, it delivers consistent clamping force and long-term durability under normal operating conditions. The design allows quick installation and a tight hold without needing specialized tools beyond common tightening devices.

Suitable for

• Securing circular ventilation ducts with 210 mm diameter
• Fastening connectors, sleeves and fittings in HVAC and extraction systems
• Repairing or reinforcing joints in residential and commercial ductwork
• Temporary or permanent mechanical fastening where a metal clamp is required

Key specifications

• Compatible nominal diameter: 210 mm
• Material: metal fastening band suitable for ventilation use
• Function: mechanical clamp for circular duct connectors and fittings
• Application environment: ventilation and extraction systems

How to use

Place the clamp around the joint where two circular duct ends, a connector or a sleeve meet. Position the clamp so it sits evenly over the joint area, then tighten using an appropriate tightening tool or screwdriver until the clamp applies firm but not deforming pressure. Verify the joint is aligned and sealed as required for the installation; if necessary, combine with suitable sealing tape or sealant according to the duct system specification. Periodically inspect the clamp during maintenance to ensure continued tightness and integrity.

Usage recommendations

Use the clamp in accordance with the duct material and system requirements. Avoid over-tightening to prevent deformation of thin-walled ducts, and where airtight connections are required, supplement the clamp with appropriate sealing materials. For installations in corrosive environments, select compatible materials or protective measures to maintain long-term performance.
