Installed 4 overhead blast gates which meant I had to re-design the original ducting as the main line run has to be 10”-16” away from wall instead of butt up against wall to give space for the internal manifold (?) swing for open & closed.
Also screwed to the wall my version 3? 4? blast gate. Has a rubber banded back end to eject dust & debris when fully closed (at least, I hope!). Air gunned 8 nails per side to firmly hold the 6” HVAC 4” piece into the wood.
Satisfied with the first drop, I have 4 more to go…
