Place	the	expanding	aluminum	“snorkel”	on	the	ceiling	flange	and	cinch	
it in place using one of the band clamps.
The snorkel expands over a fairly wide range. It should be lengthened until 
is it slightly taller than is needed for the joists in your installation. If your 
attic has joists that are smaller than 2” x 8”, you may need to trim the alu-
minum to a more suitable length using a utility knife. 
Caution!
Be certain that the snorkel can be compressed somewhat before 
proceeding to the next step. Once it is fully compressed, any further 
pressure placed on it will be transferred directly to the ceiling.
