- two sealing lips providing more flexibility
- fastening with notches
- reinforce lighter gauge ductwork
The MEZ-CIRCULAR FLANGE BF 30 has two circumferential flared edges which cling to the duct and ensure a lot of flexibility. The MEZ-CIRCULAR FLANGE BF 30 is made of galvanised steel and is for ducts with a nominal size of 300 mm. An advantage of the MEZ-CIRCULAR FLANGE BF 30 is that it reinforces lighter gauge ductwork. The circular flange is fastened by notches or in some cases self drilling screws or blind rivets. The MEZ-CIRCULAR FLANGE BF 30 is suited for Stiffening Ribs, Spirally Wound and Straight Seams and is connected with the MEZ-JOINING CLIP SR.
