This product may not be suitable for ventilation ducts with diameters other than 104 mm, as the bracket is specifically sized for this dimension. It is also not intended for use in high-temperature industrial exhaust systems or environments where the material may be exposed to corrosive chemical vapors that exceed the specifications of the bracket's construction.
Key specifications

Shape: Round
Application: Duct mounting and stabilization
Material: Durable synthetic construction
To use the DOSPEL System D/UMO, first determine the optimal placement along the ventilation route to ensure proper support for the ducting. Position the bracket against the mounting surface and secure it firmly using appropriate fasteners. Once the bracket is fixed, insert the 104 mm ventilation duct into the circular opening, ensuring a snug and stable fit. Verify that the duct is aligned correctly and that the bracket is tightened sufficiently to prevent movement.
What to consider before purchase
Verify that your ventilation duct diameter is exactly 104 mm
Ensure the mounting surface is suitable for the bracket's attachment method
Check the total weight of the ducting to ensure the number of brackets used provides adequate support
For optimal system performance, it is recommended to space the mounting brackets at regular intervals along the duct run to prevent sagging and ensure consistent airflow efficiency throughout the ventilation network.
