506E4

Maximum connection reliability for stable air duct joints

The MEZ-LATZ 506E4 – 3 mm – AISI 304 offers a robust, reliable solution. Designed as a high-quality air duct clamp, it ensures a permanently secure air duct connection for Systems 20, 30 & 40. The AISI 316 stainless steel construction, the 3.0 mm material thickness and the sturdy ribbing across the bend ensure maximum rigidity. This is ideal for high-pressure systems, demanding installation conditions and everyday industrial use.

Thanks to the well-thought-out hook design, the air duct clamp can be easily hooked onto the bead of the flange profile, tilted over the opposite profile and then securely tightened. The result is a precise, profile-matched press fit, a stable connection and minimised installation effort.

In practice, fitters and manufacturers often face the same problem: air ducts must be connected to one another quickly, reliably and with a permanent seal. This poses a particular challenge with longer edge lengths and high pressure levels. Standard duct clamps often offer insufficient stability in such cases or cannot be fitted neatly.
