The best one might be straw. North West Electric Co. about 30 years ago needed to hang lighting and conduit from a straw ceiling in a gymnasium. The location was in a town known as Bellevue, Wa. The straw was held together with a light weight concrete spray type impregnated coating. They formed the material in small blocks ie., 3' X 4' ten inches thick. They ended up using extra large toggle style bolts to hold the channel and or other mediums. We used to have a baseball stadium called Sixth Stadium. Our ball team was called the Seattle Rainiers. We used to have a beer called Rainier too. One of the soda companies put up a distribution center. For their roof they used light weight domed concrete dropped into location, pieces about 10' X10'. As thin as one inch. How do you hang four inch fire suppressing lines, sprinkler etc..? Rawl Plug Company made a fastener they call H/S. It's a short profile, two piece, high strength steel flush anchor. Next day air freight from the east coast and the customer was very happy. They still had a few failures drilling the thin concrete, but no problems with the anchors. Good job Rawl Plug. Of all the concrete fastener manufacturers in the industry, I truly believe Rawl is the best, highest quality, most dependable and a leader all others follow repeatedly. There is always one company that is the best!

Threshold fastening can end up being a difficult job with the wrong fastener. Use care when using plastic style fastener systems. The best one I've worked with was the Rawl Plugs' fiber anchor. It's has a hard fiber outer shell and a lead inner hollow core. What an anchor! How about over two thousand pounds on a number ten screw. Very vibration resistant, what a threshold anchor - no call backs. What's a call back? Another unneeded expense. Maybe your next job! It takes a life time to build a good reputation and with one mistake it can be lost.
