Description
LB-15 is a decorative linear aluminum grille used for introducing or evacuating air.
The grille is recommended for installations with constant or variable air flow.
LB-15 can be applied to the ceiling or wall.
The grille blades are fixed and parallel to the “L” (length).
For grilles with a length > 3m, the execution is modular, and the product is delivered together with the necessary connecting elements.
Depending on the overall position, the modular parts are built without termination elements or with a single element – see assembly sections.
As standard, the grille is manufactured with holes for screw mounting.
The product is delivered with fixing screws painted in the shade of the product.
