Hook Bracket Double for Flexible Duct 2x75 mm SpiroFlex (pack 25)

Double hook bracket designed to support two flexible ducts with 75 mm internal diameter each. Manufactured by SpiroFlex, this pack of 25 metal brackets secures paired flexible air ducts or hoses in ventilation, HVAC and extraction systems. The bracket is intended for wall or ceiling mounting where two ducts run in parallel and require a compact, stable anchor point to maintain alignment and prevent sagging.

Advantages

This double hook bracket offers a compact, space-saving solution for routing two flexible ducts together. It provides reliable mechanical support to reduce strain on duct joints and connections, helping maintain airflow integrity. The standardized sizing for 75 mm ducts ensures compatibility with common flexible ducting used in residential and light-commercial installations. Supplied in a pack of 25, the set simplifies procurement for multi-point installations and helps ensure consistent mounting across a project.

Suitable for

• Mounting and supporting two parallel 75 mm flexible air ducts
• Wall or ceiling installations in ventilation and HVAC systems
• Extraction hoods and small duct networks in residential or light-commercial buildings

Key specifications

• Compatible duct diameters: two flexible ducts, 75 mm each
• Quantity per pack: 25 brackets
• Mounting type: wall or ceiling fixed mounting
• Material type: metal construction suitable for mechanical support
• Design: double hook to hold two parallel flexible ducts securely

How to use

Select mounting locations at regular intervals along the duct run to prevent sagging and maintain proper slope where required. Position the bracket so each 75 mm flexible duct sits fully within its respective hook, ensuring the duct is not pinched or overly compressed. Secure the bracket to a suitable substrate using appropriate fasteners for the mounting surface (masonry anchors, wood screws or sheet-metal screws as applicable). Confirm alignment of both ducts and tighten fasteners to provide stable support while leaving a small clearance to avoid damage to the duct wall.

Usage recommendations

For best results, space supports at intervals recommended by the duct manufacturer and avoid locating brackets at sharp bends. Inspect mounting points periodically for corrosion or loosening, and replace brackets if deformation or material fatigue is observed.
