I don't know what ya call it... that square 'ring' that slips in the vent fan opening, on the interior , to frame out the vent. Ya know, in the ceiling?
Well, it's hard plastic and I know it's mentioned before about having to trim it to fit. I do - about an inch.
What's the best/easiest way to cut it?
Thanks...
ps... building is moving along, taking pics but home computer is broke so I'll catch up later.
