Once you have settled on the fire position and are confident the 150mm hole for the
sleeve will be clear of roof beams and wiring, and are confident you can reach the bolts
when they protrude through the floor( to get the nuts etc on) , mark the 4 holes for the
fire.
3.
Drill the 4 holes and use M10 high tensile bolts, if the floor is thin ply etc then fit some
flat steel straps on the bottom side for the nuts to pull up on, make sure it is secured a
strong floor, if in doubt add a chain to a protruding bolt and bolt other end of chain to the
chassis.
4.
Mark the centre and drill a ¼ “ pilot hole through the two layers of the roof, you may
need a long drill (make sure drill is kept straight with the line the pole was, get an
assistant to watch drill and make corrections if needed)
5.
Use any access such as the removed speaker in this photo to check what is in the roof
lining, i.e. wires or beams.
