For $136.68, why isn't the pail shelf option included ? !

Asked by: WAHomeowner
I really believe that the asking price for this ladder is more then fair considering that this ladder will most likely outlive me. This ladder is that good. This ladder most likely will be handed down to my son when I am no longer around.

Rated 5 out of 5 by from So glad I made this choice! This was a great experience all around. I had wanted this ladder but kept putting it off. Finally decided to do it but the only source was out of town. I ordered the ladder, it arrived quickly for in store pick up. The transaction was quick, ladder loaded and I was off! This is a very tough, durable ladder yet easily manuervered into place, carried, and feels steadier than any of my other ladders. The twin sides are great! It has been home a week, tall hedge is trimmed! Next will tackle the windows.

Rated 4 out of 5 by from Great Ladder! Great ladder, nice that you can either straddle the ladder using the rungs on both sides or two people can stand on it in case you need an extra pair of hands.

Rated 5 out of 5 by from Bought for the wife and mother-in-law My wife and mother-In-law Needed a short ladder that could be shuffled around the house while decorating while allowing g them both to stand and work at the same time....this ladder does both!

Rated 5 out of 5 by from Great Ladder This Werner ladder is well-built and tall enough to let me reach the eves of my roof safely. Having steps on both sides allows me to have a helper with those tall jobs. A very pleasant discovery was that this ladder is rated for 375 pounds for EACH side!
