AP-20 Aluminum Work Platform Type II is rated 4.9 out of 5 by 7.
Rated 5 out of 5 by from AP-30 Needs a Center Handle The only way to improve this platform is to add a center handle. Perfect Height for cutting in a standard height room when painting. I am constantly setting down paint and brush to use two hands to move. It can be done with one hand but it's awkward and noisy to toss or drags the drop cloth. Wouldn't it be nice to hold the paint pail with one hand and pick up and place the platform with your other free hand. Sounds like a lame complaint, but time is money in the trades.My most used ladder. Light weight and durable. Designed by someone who doesn't actually use one all day.

Rated 5 out of 5 by from Great product! This product will become indispensable, like my 8 foot Werner step ladder. My boyfriend gave me one of these work platforms as a gift (whattaguy!!) after I'd used one at his place. I'm a shorty, 5'4", and a handy gal. Way better than a short ladder, I like that it gives me a better vantage point and sturdy access when I wash the top of my SUV. Definitely will use it for painting. I agree with the other reviewer about creating a hand hold for ease of relocation. It is SO sturdy, especially with the rubber feet, I was thinking, WOW, what an outstanding portable work BENCH this could be if the legs could extend and adjust to between 30-40 inches, and have the platform a little wider, 24-30" (or larger). Recently sold my house to relocate and am renting right now, and all I have is a small carport for storage and work space. If I had a storable workbench similar to this design I could quickly erect it, utilize the compound saw on it, or use as a surface to construct or paint an item, and/or clamp my work so I don't have to bend over and kill my back...I'd be digging it. WERNER...PRODUCT IDEA!! I'll be first in line at the register!

Rated 5 out of 5 by from AP-20 Platform Nice product from a reputable company. Picked a few of these when on sale locally. One improvement that Werner can implement on this model. The rubber feet on the legs are riveted on. The issue with this is that the legs will eventually wear through the rubber feet and possibly damage hardwood floors, ceramic tile, etc. Well, I have a fix for this that Werner can implement.Remove the rivets securing the feet on. I used a 7/32nd bit to cleanly remove rivets. Next cut 4 sheet metal pieces to this size. 1" x 1 3/4". Place the pieces into the rubber feet cavity, they should fit snug. This allows the sharp angel leg to rest on the layer of sheet metal sandwiched between the rubber and the leg. Place some 100% silicone caulk, I used clear, and refasten each foot to each leg using a #14 sheet metal screw, I used a 1" length screw. I just improved this product so I'm not damaging floors and simply prolonged the lifetime of the actual rubber feet. Call me Werner for details if you like pictures on my ideal.

Rated 5 out of 5 by from Great Product, Just bought my second one. An excellent product beats stepladders by far. Just got my second one in 20 years.

Rated 4 out of 5 by from Perfect, except. I have owned this product for at least 10 years. Over those years I have grown to love it and use it in many ways. Most recently I was painting some crown molding in my house. The platform is the perfect height for my 5'-10" frame. And the length allowed me to cover about a 4' section of molding before stepping down to relocate. During this most recent enjoyment I found that your product needs, very badly, a slot located in the middle of the platform so that it can be moved with one hand while the other hand holds a paint bucket and brush. This improvement will allow the user to pick up the platform in a level manner and relocate it without dragging it across the floor and banging it into adjacent walls. Please consider this improvement in your next production run. Thank you.

Rated 5 out of 5 by from The best you can buy. I installed large rolling doors in a hotel on the coast. I borrowed this platform from hotel maintenance to allow me to move freely along the track. Now I am building cabinets for 70' to 155' yachts, and I sometimes need to be... higher, beside my workbench. I looked at many other similar products. I saw flimsy material, shaky legs, and questionable latches. Save yourself the time and just buy the Warner quality. A few extra dollars might save your life.

Different specs at the local retailer.

Your model on the website indicates a width of 50-1/4". The same model (AP-20) at Home Depot has a width of only 39'. Where can I get the model that is indicated on your website, which I prefer?
Asked by: Rich
The stated width of 50-1/4 inches is the overall width of the AP-20 on the ground, where the legs extend out. The ground foot print measures 50-1/4 x 15-5/8 inches. The platform area which a user can stand is 39-1/2 x 12 inches.

I have the AP 20 model work platform and I was using it recently. When the platform gave way while I was on it. I had purchased it maybe five years ago at my local lowes store. I really enjoy using it a lot and would like it replaced if possible.

Different types of ladders are designed to keep you safe and productive when climbing or standing. Using the wrong style of ladder or simply ignoring the limitations of climbing equipment can result in a fall or serious injury.
Height is referring to the actual ladder height. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. The highest standing level is four rungs down from the top. The highest permitted standing level on a stepladder is two steps down from the top.

Reach height is the maximum reach assuming a 5’6” person with a vertical 12” reach.
Ladders are designed to safely hold up to a specific amount of weight. The Werner Performance System defines five different capacities using a color and star rating system. The Duty Rating is defined as the maximum safe load capacity of the ladder. A person’s fully clothed weight plus the weight of any tools and materials that are carried onto the ladder must be less than the load capacity.

Werner offers ladder made from fiberglass and aluminum. Each material has characteristics which make it best for certain applications, or one material may simply fit the personal preferences of the user. For example, if working around electricity users should select fiberglass products due to their non-conductive side rails.
