| SINGLE & DOUBLE DEFLECTION ADJUSTABLE GRILLES |
 |
ADJUSTABLE GRILLES (SDG SINGLE DEFLECTION and DDG DOUBLE DEFLECTION) are suitable for supply air for either sidewall or exposed duct applications. The single or double row of blades permit up to 45 degree deflection of the air, in either one or two planes. Link Blade (LB) and fixed blade applications are available (front blade only). SDG and DDG grilles are manufactured from extruded aluminium sections, the mitred corners being fully welded and linished. Finally they are stove enamelled silver 'Analum' as standard. Other finishes are available |

| Grilles are available to fit duct sizes from 100mm x 100mm up to 1200mm x 750mm as a single unit. Larger units may be produced by reduction of flanges to give internal mullion appearance. The front blades are always parallel to the first dimension. Thus a grille ordered as 600mm x 300mm will not be the same as a grille 300mm x 600mm. |
| Fixing Methods FMA - Screw fixing (standard). FMB - Subframe with concealed screw fixings (suitable for a maximum face area of 0.36m2). FMC - Subframe and spring clip. FMD - Spring clip only. |
