Key Highlights
  • Clamp-Free Threaded Round Connection — Built-in threading on the round collar end locks directly onto flexible aluminum foil or semi-rigid aluminum dryer duct without clamps or duct tape, saving installation time and reducing leak points.
  • Solves Round-to-Oval Transition — Bridges the gap between standard 4" round dryer transition duct and common in-wall oval ductwork, accommodating the most frequent mismatch encountered in dryer duct installations and replacements.
  • Galvanized Steel Worm Drive Clamp Included — A 4" galvanized steel worm drive clamp is included in the box for securing the oval end to the in-wall duct, eliminating the need for a separate hardware purchase.
  • Tool-Free Disconnect for Cleaning — The threaded connection disengages quickly without tools, making routine dryer duct cleaning and lint removal faster and more accessible for homeowners and service technicians.
  • High-Impact Polystyrene Construction — Durable white high-impact polystyrene body resists cracking and deformation during installation and normal dryer operation, maintaining a secure duct connection over long-term use.

Product Description
The Dundas Jafine R20ZW is a 4" round-to-oval dryer duct adapter designed to connect standard round dryer transition ducting to existing in-wall oval-shaped ductwork, solving one of the most common dryer installation challenges without requiring duct modification or special tools. Constructed from high-impact polystyrene in white, the R20ZW features a built-in threaded connection system on the round collar end that securely attaches to flexible aluminum foil or semi-rigid aluminum dryer ducts without clamps or duct tape — the threaded design provides a firm, rattle-free connection that can be quickly disconnected for routine dryer duct cleaning and maintenance. A 4" galvanized steel worm drive clamp is included to secure the oval portion of the adapter to the in-wall oval duct for a complete, tool-minimal installation. The adapter fits 4" (10.2 cm) collar sizes and is sold individually.
