Any ideas on what I could use in place of toggle bolts, Vanity fixture approx 20 lbs manuf ships and recommends using their black toggle bolts. Drill holes for toggles and vent pipe is directly behind one of the holes. I can try to shorten the bolt, but don't think I can get the bolt far enough in to let the toggle open up
hilti toggle bolts. about a buck each at home dipsnit.
use 1/4" ones... you can snoodle them in place and they will stay without
a bolt in place... then you can use 3/4" or 1" bolts to hold the fixture without
bottoming out.
if it's a black iron riser, those make wonderful backing.... they make killer tek
screws that'll go thru 1/4" steel plate, and self tap......
hey... if it's just a vent riser, it's just air.......
