Colt 3UL Universal Louvre fixed metal weather louvre system

Colt 3UL Universal Louvre is a roll-formed triple bank louvre system designed for applications requiring ventilation with the maximum degree of rain defence.

When high level rain defence is needed, we recommend the use of either 2UL or 3UL. When rain defence is not of primary importance, we recommend the use of 1UL.
