The MT Series is available in four models--MT-13, MT-17, MT-22, and MT-26--allowing the choice of the perfect size for individual applications.

Twin Stepladder Position Supports 300 Pounds Per Side
When set up as a stepladder, the Werner MT Series has a load capacity of 300 pounds per side, including person and materials.

Easy Conversions and Height Adjustments
Each ladder's inner section allows it to be folded into three set positions: extension ladder, twin stepladder, and storage. Each of these configurations is made possible by using the push-knob locking hinges located on the sides of the ladder.

Height adjustments are also a snap thanks to the spring loaded J-locks. Simply disengage the J-locks on either side, telescope the section out to the desired length (in one-foot increments), and then reengage the J-hooks.

Durable and Safe
MT Series Telescoping Multiladders are just as durable as they are versatile. Double-riveted steps provide long-lasting durability, and an extra wide flared bottom provides firm support. What's more, smooth curved side rails provide comfort and safe climbing, while heavy duty non-marring feet provide slip resistance.

COSCO was the first to clone the Little Giant Ladder about five years ago. Apparently, Little Giant's patent was still in force for the hinges. I own the COSCO 17FT Worlds Greatest Ladder and used it for a couple of years, but I needed something longer.

In January 2002, I purchased the Type 1 22 FT Little Giant from Amazon.com. The only difference was the hinges and a few annoying braces in the climbing area of the two narrow extension pieces of the COSCO. The COSCO is made in Korea. The Little Giant is made in USA. Both functions flawlessly to this day.

I found the Little Giant cloned at Home Depot as the Gorrila Brand ladder at Home Depot. $99 for the 13 ft model and $199 for a 21 ft model. The ladder is essentially a China made copy of the Type 1A Little Giant.

My last purchase is the MT-13 Werner. It appears to be another clone of the Little Giant Type 1A, also made in China, probably by the same company that makes the Gorilla. I know this, because both brands include a bonus set of brackets for making the scaffolding with an almost identical blow molded polyethylene case. The brackets are identical and marked Patent Pending.

I would recommend the MT-13 and the MT-17 in the Werner Brand, but I still prefer the Little Giant in the 22 ft model. It is a lighter by five pounds than the 22ft Werner but cost about $130 more.

Since all of the original Little Giant patents have expired, the hinges on the Gorilla and Werner models are identical to the Little Giant.

Of all of the models, the MT-17 would be ideal for most home owners. It will go to the second floor window of a two story house. The 22ft model will go to the roof of a two story house, but only for one with a slab foundation, not one with a basement or a crawl space.

The 17 FT model is a good balance between weight size and function. The best deal would be the Werner MT-17. The quality of materials and assembly of all the models appear nearly equal.

One reviewer noted that these ladders were hard to extend. The best method is still the method of extending the ladder using the procedure described in the Little Giant Instructional Video. Since the methods are copyrighted by Little Giant, the clone manufacturers cannot use them with their own instructions sheets, videos or manuals. Accordingly, I cannot include the Little Giant Procedure in this review.


Just the right ladder for a single story house on a slab....   November 22, 2004

As a contractor, I use a lot of ladders.

COSCO was the first to clone the Little Giant Ladder about five years ago. Apparently, Little Giant's patent was still in force for the hinges. I own the COSCO 17FT Worlds Greatest Ladder and used it for a couple of years, but I needed something longer. The only flaw in the COSCO are the angular steel braces on the inside of the ends of the center hinged section. These are a bit annoying, when you are using it as an extension ladder.

In January 2002, I purchased the Type 1 22 FT Little Giant from Amazon.com.

The 13ft. (Actual length is 11ft. 13ft is an OSHA rating, since extension ladders have overlaps.) ladder is ideal for a one story house on a slab or a trailer. When I first used it to get on a roof of such as house, I thought it was a little short. However, after using it several times, I found that it was ideal. The key is to place the space between the top and the second rung at the edge of the roof. I know that ladder makers recommend a grabbing length of three feet above the roof edge, but you would have to go around the side of the ladder's length above the roof. This "grabbing length" is a little arkward to me. Since the top of this and other Little Giant clones have flared tops, I prefer my method. I can stoop dowm and climb directly onto the roof, while keeping my center of gravity very low. The same can be done, while getting off of the roof. So the 13ft. ladder is just right. The thing I really like about this length is easy handling. It balances well, when fully extended and makes a compact package that fits nicely into a car trunk of even some compact car. In the step ladder mode, it is probably the sturdiest and safest that you could ask for.

For the price, the Werner MT's are the best deal. Best of all, the MT-13 is only $99 at Lowes.

I bought this for $100 from costco and am extremely satisfied. I have never had an extension ladder because I had no room to store one. This stores in less space than my 6' step ladder and gives me an adjustable step ladder that goes from about a 4' step to about a 9' step. It also works like a 17' extension ladder. It is more rigid than an extension ladder, giving noticably more stability. In stepladder mode it can be adjusted for unlevel surfaces, which is very convenient. It is a little heavier than my fiberglass stepladders, but not too bad. Also it sticks a little when I try to unlock the angle of the ladder. This is a fantastic concept and is well implemented by werner and is definitely the right ladder for me with my limited storage space. It is the only ladder I use on my 1 /12 story house and my one story rental houses. There are a couple things different ladders can do that I would like. An MT-13 (or the gorilla version, $100 at home depot) would likely fit in my trunk, which the MT-17 will not do. I would not give up the extra length to get this, though. Little Giant ladders have some nice affordable accessories (ladder stabilizer, leg levelers) that I would like. I will not pay two to three times more for the little giant, though, and hopefully these will soon be available for the werner MT series.

I purchased the MT-22 about a month ago from a local Sherwin Williams dealer (price was $180). I brought it home and tried out all of the different arrangements for the ladder and found it to be very easy to use with the exception of the extension part. It weighs 45 lbs. which really isn't a big deal to me. I am 6'4" tall and I workout so the weight wasn't a problem. I found the best way to use it as an extension ladder is to fully extend the opposite end of the ladder first, then lean the ladder against the building, pull the adjustment pins and push the ladder upwards. I don't know if this is the best or correct way, but it works for me. I also talked with a rep from Werner and the working platform and leg levelers should be available in the beginning of September.
The ladder is very solid. I put Sikkens on my deck and used the ladder as 9 foot step ladder and it didn't sway or tip at all. I am very pleased with this product.
