slightly special ladders

Gentleman/ Ladies, We buy multiple ladders for platform and handrail systems we install on cooling towers. We need aluminum ladders with plain ends, no feet, and "O" rungs. We currently have a need for 6, 10 ft. ladders. Could you please give us a price for these ladders or refer us to a local vendor in the Washington, DC, / Baltimore, MD. area from whom we could purchase these ladders? Thank you very much. Gregory Hetman Chesapeake Systems
Asked by: Gregory Hetman
We do not have anything available like this. Our straight ladders would be close but they will come with feet and toppers.

Can this ladder be used in a vertical application if it is secured at top and bottom?

Asked by: Climber
The aluminum straight ladder model 518-1 is designed to be used at a 75 degree angle. Setting up the ladder at the proper angle will help reduce overloading and slip hazards.

single ladder

To clean my chimney, I need a 16ft single ladder that I hook on the top of the upper roof. I have one: type 2 commercial 225#. I am only 160# and I find this ladder very heavy to move from the first roof to the second. Do you have a ladder of the same size but lighter?
Asked by: Bernie
We currently manufacture 2 single aluminum ladders with a height of 16ft. Please see the 516-1 and the D1516-1. The 516-1 weighs 37lbs. The D1516-1 weighs 32.5lbs.

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.
