Rectangular Branch

The AD-VK rectangular duct take-off is designed for connecting a duct of one size or cross-section to a ventilation system of a different size or section. This fitting allows fast and airtight integration of additional branches into an existing ventilation network while maintaining optimal airflow performance.

Before installation, apply a layer of silicone sealant between the take-off and the duct to ensure tightness and secure it using self-tapping screws or rivets. Using AD-VK rectangular take-offs simplifies ventilation system installation and improves operational reliability.
