AIR DUCT CONNECTIONS
Universally applicable air duct clamp – ideal for coupling
rectangular air duct systems of all Duct cross-sections
- Fastener for economic and time saving
mounting and demounting
- specially suitable for inaccessible points,
e.g. air ducts, which are tightly fixed onto
the ceiling or wall
- A gap of 5 mm between the cover and the
duct profile is all that is required
- Pre-assembled with hexagon bolt
MEZ-WEDGE
- for MEZ-FLANGE SYSTEMS 20, 30 and 40

Workmanship + Assembling:
- Hang the duct clamp with the hook-shaped end onto the bead
of the flange profile – tilt over the second profile and
fasten using screw (do not tighten!)
- Using construction spanner, insert duct clamp into the
air duct connection and tighten screw
- When tightening, the wedge presses itself onto the profile
thereby providing for a reliable connection
- Abstain from excessive tightening – this could lead to a
distortion of the profile.
Tips:
- Minimum gap between ceiling/wall to the duct profile: 5 mm

- The duct clamps need to be mounted in such a way that the
distance between two connections does not exceed 500 mm
