LARTDESmoke Collar

The collar connects to rectangular ducts. Trapeze corrugations stiffen the duct and reduce the risk of noise generation. Pre-wrapped 25 mm silver-coloured insulation insulates the outside of the product.

The smaller connection end has joining profiles of 30 mm flange. The larger connection end has an edge for fixing with blind rivets or self-tapping screws. A folding tab can also be added to facilitate assembly.

The product is CE marked according to EN 12101-7 and used in a rectangular smoke control system – multi compartment (see Declaration of Performance).
