Clamping Band AWENTA OP3 Ø110–130 mm, model OP3

Clamping Band AWENTA OP3 Ø110–130 mm, model OP3 is a metal strap clamp designed to secure circular ducts and pipes with diameters between 110 and 130 mm. Created for use in ventilation and plumbing installations, this clamping band provides an adjustable circumference and a mechanical fastening method that ensures a firm hold around round components. The simple construction enables straightforward assembly and reliable reinforcement of joints and connections in residential and commercial HVAC systems.

Advantages

The AWENTA OP3 clamp offers adjustable sizing to fit a range of diameters, reducing the need to stock multiple fixed-size clamps. Its metal strap design provides mechanical strength and durability for long-term duct support. The clamp’s straightforward fastening mechanism allows quick installation and secure tightening without special tools. The compact profile minimizes interference with surrounding elements while maintaining a stable hold on circular ducts and pipework.

Suitable for

• Securing round ventilation ducts with diameters from 110 to 130 mm
• Mounting and reinforcing pipe connections in HVAC systems
• Repairing or strengthening joints in residential and commercial ductwork
• Temporary or permanent fastening of circular conduits during installation

Key specifications

• Compatible diameter range: 110–130 mm
• Material: metal strap construction for mechanical strength
• Adjustable circumference suitable for small diameter variations
• Fastening type: mechanical strap clamp for tightening and securing
• Intended application: ventilation and plumbing ductwork reinforcement and mounting

How to use

Place the AWENTA OP3 clamping band around the circular duct or pipe so the clamp overlaps the mating edges. Adjust the strap length to match the component diameter within the 110–130 mm range, then engage the mechanical fastening mechanism and tighten until the band firmly secures the duct without deforming it. Ensure the clamp sits evenly around the circumference and re-check tightness after initial operation or vibration. For joints, position the clamp to bridge the connection point and tighten to compress any sealing material as required.

Usage recommendations

Use appropriate hand tools to tighten the metal strap evenly; avoid over-tightening that could deform thin-walled ducts. Inspect clamps periodically in installations subject to vibration or thermal cycling and re-tighten or replace as necessary. For corrosive environments, verify material compatibility or use additional protective measures.
