Curved Shoe (TBS)

Manufactured from high-quality galvanised steel, this collar saddle provides a strong, durable branch connection for circular ductwork systems. Designed for professional HVAC and ventilation installations, it is suitable for low, medium and high-pressure applications and is manufactured in accordance with DW144 ductwork standards. Sizing First measurement = Branch Diameter Second measurement = Parent Duct Diameter For example, 200mm × 315mm represents a 200mm branch connection designed to fit onto 315mm diameter parent ductwork. Improved Airflow Design The profiled saddle design provides a smoother transition from the main duct into the branch, helping to reduce airflow resistance and turbulence compared with a conventional straight collar saddle. Installation Cut an appropriately sized opening into the spiral or plain circular ductwork, position the saddle over the opening and secure it using rivets or self-drilling screws. For an airtight installation, seal around the joint edges using a suitable duct sealant, silicone or acrylic sealing compound. Key Features High-quality galvanised steel construction Designed to suit circular spiral and plain ductwork Suitable for low, medium and high-pressure systems DW144 compliant Profiled design for improved airflow Quick installation using rivets or self-drilling screws Creates a strong and reliable branch connection Suitable for commercial and industrial HVAC installations
