Wonderful add-on, Takes a lot of time to install!

I gave it 4 stars because of the extra KIT 36-14, which needed to be ordered directly from Werner Ladder. Amazon does not carry it.^M

The Werner PK80-2 Level-Master Automatic Ladder Leveler is a great idea! I now feel safe when setting up an extension ladder on sloped ground. My co-worker, in his mid 20's is also impressed.^M
I purchased 2 sets and was like many others, leery of cutting off the bottom of my 24' Werner ladder. I now understand the reasoning. It is to allow the feet to run their full travel up and down and allow the ladder to level out on a pretty steep slope prior to raising the extension.^M
I never would have purchased these things if it weren't for my brother in-law hiring me to build a 2-story addition on the back of his house. If you fall down near the house while standing, you would roll to the bottom of the hill. Setting a ladder on such ground was not going to work for me.^M
Now that I cut off the bottom of the ladder and installed the levelers, I can't imagine why I would want to ever remove them as a couple of others stated. I consider them a great improvement to a standard ladder. They work great on even the slightest angles. No more rocks and or lumber to build up one leg, and then hope while up at the top, the bottom will stay put!^M
I agree that the installation of my first unit was complex and time consuming. 2 plus hours (close to 3) and a lot of reading (and skipping pages) to make the installation on my D-1500 series ladder. Also I will agree that the "kit" needed to make the installation should have been included for the price. Very inconvenient to have to call Werner to order the 36-14 kit needed for the D-1500 ladders. Amazon doesn't carry it.^M
The second unit will go much quicker now that I know the principle of the various steps involved. Like anything else that one does for the first time, AND following directions written in full detail added time but is a necessity. I think the next one will take about an hour, maybe less. I have 4 ladders and eventually all of them will have these levelers.^M
One other issue that will take some getting used to is not being able to go to the middle of the ladder to carry it. The weight of this unit requires finding the center of gravity a few rungs closer to the bottom, something I'm just not used to doing. Also loading the ladders on my truck requires some getting used to do to the fact the levelers protrude out from the ladder sides. These are little things when you look at the overall picture. I'm sure the old tradesmen gone by felt the same when they started switching over from wood ladders to aluminum!^M

unsafe

i had a mechanic install it, we used it for about 10 minutes and none of my guys are willing to touch it again. this thing is bound to fail. returning it tomorrow.

great product

I have installed this on a louiseville fiberglass ladder. This product works as well in this ladder as on the werner ladders. The instructions are good once you determine what template to use if you are not modifying a Werner ladder. Takes a couple of hours because you need to make sure that each step is followed closely as if you mess up you will have a $250+ ladder with no feet. But is you do this the product works very well. A little silicon spray when you first use it makes the mechanism work even better.
