View Full Version : Uni-strut question!!!!!!!!

09-19-2011, 06:53 PM
I have 2 one inch copper pipes hanging horizontally at my ceiling. They are held by strut clamps attached to uni-strut for about 30 feet across the ceiling. The uni-strut bars (8 inches wide) are also only about 6 feet apart. Some of the uni-strut itself has came unattached to the ceiling do to the weight of the pipes. The ceiling is drywall and the uni-strut was fastened with plastic threaded drywall anchors which are no good due to the anchor hole being larger now. The pipes now have a significant bow to them due to the uni-struts in the middle coming all the way off the ceiling. I was wondering if it is okay to reattach the uni-strut without it causing harm to the pipes already bowing in any way and if so what is a better anchoring system?(...anything better than toggle bolts?)

You should reattach the unistrut. Maybe toggle bolts will be the only way if the plastic anchors pulled away.

As an alternative to toggle bolts, there are other plastic toggles that work. One that is designed to hold a considerable amount of weight is a unique one by www.wingits.com (http://www.wingits.com). They make a neat SS one specifically for shower safety bars, but have some plastic ones that commercial places tend to use for things like towel bars in hotels.

I would change the supports so that they are attached to the joists instead of the drywall. Depending on which direction the joists are running and their position in relation to the pipes, you might need to install some longer pieces of uni-strut to span 2 joists.

WI plumbing code allow 12 feet between hangars, but I would only go half that distance.
