Electric Screwdrivers

We use stainless steel cross headed screws painted black for our mouting. Many have asked about moving to hex heads, and we are looking at this. But they are bulky and dont really look good. We have found that an electric scewdriver, such as the one sold at Sears, are ideal for installation of our unit because they are short. This is important in the back screw if your pitch is above 7.
