MEZ-CORNER 40 - 120

Precision corner brackets for stable and airtight air ducts

In practice, manufacturers and fitters of air ducts frequently face the same problem: corner joints must offer high stability, precise alignment and long-lasting airtightness – even under load and with large duct dimensions. Imprecise angles or material weaknesses quickly lead to leaks, rework or installation delays.

The MEZ‑CORNER 40 – slotted – galv. solves precisely these challenges. As a galv. corner bracket for the MEZ‑SYPHON‑FLANGE system 40, it is inserted through the duct wall and, thanks to its 4.0 mm material thickness, 30 mm offset and 26×13 mm slot, ensures a particularly secure, force-fit connection. Its robust design guarantees precise positioning within the frame and increases the rigidity of the entire air duct – ideal for airtight, durable and standard-compliant constructions in ventilation and building services applications.
