Rated 5 out of 5 by from Good ladder I recently purchased it due to the good price and excellent reputation. As a former paint contractor, I know the brand very well. I hate the weight of fiberglass ladders, so I chose aluminum. You can't go wrong with it.

I need a ladder that is all aluminum with no ferrous metal parts.

Is the 388 6' alluminum ladder all aluminum?? Dennis Amaral Dignity Health Medical Foundation.
Asked by: Anonymous
Unfortunately we do not offer a ladder that is absent of ferrous material. I assume you are seeking a ladder for a MRI room and unfortunately our ladders can not be used in those environments. Thank you for your inquiry.

Does Werner sell replacement parts for older Model 366 6' step ladders?

I need replacement feet for a Model 366 6 foot aluminum step ladder. When I called customer service at the number provided at the Werner website, I was told that the mark number for this ladder was 12 (it is not on my label with the model number) but that they do not stock ones for my ladder. Since there is still a ladder of this model number, size and material being sold are there not replacement parts available for those?
Asked by: Anonymous
Although the model number is still being made the design of these ladders change over time, so some parts may not be available depending on age of the ladder

6 ft. fiberglass ladder

do you have a 6ft. Fiberglass ladder that has a convenient tray or tool tray top like your 6 ft. Aluminum ladder. I perfer a Fiberglass ladder. Also what is the rating of the Fiberglass ladder if it does have this tray. Regards Yoda
Asked by: Anonymous
We do not manufacture a fiberglass stepladder that has the same top as the 366. The top on our 250lb rated fiberglass stepladder (model 6006) has a lock in top in which you can lock in several accessories.

I just bought one at Lowes. How does it open?

Asked by: Anonymous
To open the 366 aluminum step ladder, simply seperate the two sections of the ladder by pulling them apart. Once the ladder is opened, the spreader arms will be fully extended, and all four feet will sit firmly on the ground.

Black clips

I just purchase the 6' aluminum ladder at Lowes. Are the black clips at the bottom of the ladder part of the packing material or are they to be used when storing the ladder?
Asked by: Anonymous
The black clips at the base of the ladder are used to protect the ladder during shipping. These help keep the ladder legs in place to prevent damages.

how do i unlock the 360 ladder having difficulty

just received the ladder and unpacked it but can not open the ladder.what do ihave to do!
Asked by: Anonymous
When opening a step ladder for the first time, there are some packing components that are used to hold the ladder closed during transportation. The ladder may be wrapped in plastic or have a banding around the ladder. Also, near the bottom of the ladder, there are black clips that are used to keep the ladder closed. Once all of the packaging is removed from the ladder, the two side of the ladder should pull apart, using the spreader braces on the sides to set the ladder at the proper angle.

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.
