| SINGLE &
DOUBLE DEFLECTION ADJUSTABLE GRILLES - HEAVY DUTY |
| ADJUSTABLE GRILLES (SDG/HD SINGLE DEFLECTION and DDG/HD DOUBLE DEFLECTION) are suitable for supply air for either sidewall or exposed duct applications. They are particularly suited to areas with a high degree of vulnerability or damage; typically Car Parks, Sports Halls or Industrial Projects.The single or double row of blades permit up to 45 degree deflection of the air, in either one or two planes. SDG/HD and DDG/HD 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 the
use of internal mullions. 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). FME - Subframe with concealed screw fixings for larger size grilles. |
