Telescope collar MAGNAPLAST 400 RWG DO R.W.G (model 34611) for pipe connection

MAGNAPLAST telescope collar model 34611 (400 RWG DO R.W.G) is an adjustable pipe connection accessory designed for joining or extending round ducts and pipes. The telescopic design allows for variable length adjustment to accommodate slight misalignments and gaps between sections, simplifying installation and maintenance of ventilation and drainage systems in residential and light commercial buildings.

Advantages

The telescopic collar provides a secure mechanical connection with a smooth external surface that reduces air or water leakage when fitted correctly. Its adjustable length saves time during installation by eliminating the need for precise pre-measurement and cutting of duct sections. Constructed for compatibility with common RWG-sized round ducting, the collar supports straightforward alignment and can reduce the number of separate fittings required in a run.

Suitable for

• Extending round ventilation ducts
• Connecting drainage pipes where slight misalignment exists
• Temporary or permanent joins during HVAC installation and repair
• Residential and light commercial ductwork applications

Key specifications

• Telescope collar for round ducts with nominal 400 RWG size
• Adjustable (telescopic) length to accommodate alignment variations
• Designed for mechanical pipe connection and coupling
• Suitable for ventilation and drainage systems
• Material compatible with common ductwork environments (indoor use)

How to use

Slide the telescopic collar over the end of one pipe section, then extend or compress the collar until it overlaps the adjoining pipe by the recommended engagement length. Ensure both pipe ends are clean and free of debris before assembly. Secure the collar with appropriate clamps or fasteners suitable for the duct material, and if required for the application, apply a compatible sealant at the joint to improve airtightness or watertightness. Verify alignment and final positioning before completing any insulation or sealing work.

Usage recommendations

Use matching clamps or straps sized for 400 RWG ducting and check local codes for ventilation or drainage installation requirements. For exterior or corrosive environments, select additional protective measures compatible with the collar material and the connected pipes.
