Query: works for me

used this to ceiling mount viewsonic 5133 in drop ceiling. moving our projector from table top to ceiling i wasn't exactly certain where i would mount and this seemed to be very versatile had build a wood brace to mount to took about 5 min. with leftover 2x4. takes a little patience to adjust and tighten if the projector moves at all it is not tightend enough (i had to tighten joints 2 more times after i thought i was finished). assembly is easy just look at the pic on box. heavy,solid,sturdy and i like the way it looks.
