Stu was like an Air Traffic Controller for garage doors! He talked me thru repairing mine several times. He had me adjusting the spring tension one time, and asked me what I was using to twist it with....and I told him 3/8 ratchet extensions. Then he asked me what county I lived in, in NC? I told him Buncombe, and asked why. He said he wanted to know which county 911 to call when he heard a big BLAM, then a thud when those extensions slipped and busted my brains out! I have a Liftmaster 3800 jackshaft opener on my door. Sure miss Stu....R.I.P. buddy.
