(AF) EASY FIX® Angle Frame Installation
5.1
Drill out the inner row of 2mm diameter angle frame pilot holes to 4mm diameter.
5.2
Position the damper centrally in wall opening (width/height), with blades running horizontally.
Using the inner row of pilot holes, screw the EASY FIX® angle frame to the wall using drywall
screws @ 150mm max pitch.
5.3
It is not a necessity to fill the void behind the angle frame, but suitable fire rated infill may be used if
considered required for insulation purposes.
5.4
Important:
Ensure the screws ‘pick up’ the track lining the hole, so that the proper fire integrity of the
installation will not be compromised.
5.5
On the reverse side, fit a single layer pattress around the damper spigot using drywall screws of
appropriate length to screw into the steel tracking around the opening.
