Will the ladder corrode if continuously exposed to saltwater?

Asked by: Matt
Yes. It will become oxidized. You can use dish soap and a soft cloth to help clean oxidized aluminum.

Is there a "hook" add on that we could add to the D1510-1 so it can be used like a posting ladder?

We have a need for access to overhead conveyors for quick service and maintenance. Because of space issues, we can't have a platform with ladder at 16 places where we need it. Our thought was to use a lightweight aluminum ladder, hooked over a 38/" or 1/2" rod that would hold the ladder in place while the issue on the conveyor was resolved. I know they make Cable Hooks (15-3) for the fiberglass version of the ladder, but we think the aluminum would be lighter and easier to move around.

We don't offer anything for this application as you described.

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.
