STIS: What tool do I need to clean out a narrow channel between two 2x4s behind the drywall of an exterior wall of my house?
|
I know for a fact that there is no plumbing or electrical in this channel because there is already a conduit. Or there was.
This is a vertical "hideaway" conduit for hiding cables from a TV mounted high on the wall down to the speakers, boxes, consoles, etc. near the floor; there was an existing inlet/outlet at the top and bottom each connected to an end of a corrugated plastic tube forming the conduit.
This conduit was supposed to be large enough to accommodate two HDMI cables "plus enough additional room to add another 4 HDMI (or similar) cables in the future."
Instead, I discovered (while rearranging the house and entertainment setup a bit) that the conduit barely accommodated the two existing HDMI cables at the time.
So (after confirming with an A/V expert client), I removed that plastic conduit intending to replace it with a similar plastic conduit though much larger in diameter.
I have everything ready, but one thing. I need something like a pipe snake or similar articulated tool to reach into that channel and pull out clumps of cellulose insulation. Might be able to use a shop vac, but I'd prefer not too. That sounds unwise for some reason. I have some vague recollection of shop vac + cellulose insulation being a bad combination and I'm too lazy to confirm that.
But what does ST think?
