JPS1006 you are exactly right on in using the rods to go over drop ceilings. When I am running MC, I can guide the rods over existing pipe, cable whatever and keep it off the actual grid. At about 12 foot in length, it really cuts down on moving the ladder as the MC can easily "hang" on the grid edges. Naturally, where it needs support, I can come back and strap it up or use the batwings to support it. They really have been worth the price. I haven't had the problem with splintering. Maybe that is just for the Greenlee brand??? For fishing down walls...they are the greatest. The fact that they come in short sections and their flexibility has really helped too.
For DougW, after you mentioned the C-clamps, I started thinking about other ways I could use them to help me and one I came up with is to use them when pulling wire (when you don't have a helper) is to use them to support wire coming off your reels in the ceiling so that your wire is not pulling at an angle from the floor, across a T-grid, etc. This will keep the wires close together and almost work like an extra pair of hands. Try it, it works good for me. Thanks again for the C-clamp idea!!
Electricmanscott...thanks for your imput too!
