This is an 8-1/2" deep sleeve that is put into place by the electrician prior to the concrete being poured and it comes in varying widths. After the concrete sets, conduit is run through the sleeve to run risers from deck to deck. If a pour is deeper than 8-1/2", then the user will use two or more stacked together to do the job. They are made from a slippery plastic and are usually a forest green color. You would order them in sizes from 1-1/2" through 6". A 4" Crete sleeve would allow a 3" pipe to fit inside.

The "No-Dog" is a hand tool that eliminates "dog-legs" in offsets and saddles. It is a lightweight aluminum level measuring 1/2" by 1" by 2" that is clipped to the end of the conduit when making bends.You would use an offset bend to avoid an obstacle or to make the pipe conform closely to the surface it is being installed onto. This makes it easier to securely fasten the pipe and makes for a cleaner, more professional job. A dog leg is when the opposite bends are out of alignment with each other. If the pipe was laid on its side. It wouldn’t lie flat. The NO-DOG level helps prevent this.
