they are so much quicker and easier than those damn weak toggle bolts. used them to hang a heavy panel. but we also put three bolts to the stud in the middle as well. its too easy really. drill 1/2 in hole, zip it in, the zip part even snugs up and fits the hole perfect, cut the plastics off flush. and at ease stick your bolt when ready.I've used them a couple of times to hang mounts for wall mounted flat screen TVs. Work great and haven't heard of any problems and one was over a year ago.
good link, I was using my ***** to cut them off. didnt know they just snap off lolPretty cool, gotta find some of those!

pWhen I worked in the field, I was always on the lookout for new products to simplify work. Trade magazines, supply houses and other electricians always great sources and today the internet.
