Rope specs and replacement instructions available?

The rope on my D548-2 has broken and must be replaced. Please provide specs on the rope and a copy of the rope installation instructions. Google search yields virtually no info.
Asked by: Anonymous
The Werner Co does offer a rope replacement kit for the D548-2. The rope kit contains the proper diameter and length of rope required for the ladder. The kit also contains instructions for the proper way to reassemble the rope.

The collapsed length of my fiberglas extension ladder is approx. 12'-6". What length would this ladder be considered?

Asked by: Anonymous
The length of a ladder is measured by the total length of the rails, both sections. If both sections of the ladder are 12 feet long, this would be a 24 foot ladder.

What are the biggest noticeable differences between the D540-2 and the D1540-2?

Both are rated to hold 300 lbs but I noticed the base on the D540-2 was 1" wider and that it weighs roughly 10 lbs more. What I am specifically wondering is will the D540-2 be more rigid when extended vs is comparable D1540-2 and if the D540-2 actually is rated for above 300 lbs but not quite enough to meet the 375 lb. rating of the next class above
Asked by: Anonymous
The D540-2 is not going to be more rigid than the D1540-2. They are both manufactured by the same type of aluminum. The only big differences are that the D540-2 has internal guides that allow the fly section to slide smoothly on the base section. The D1540-2 uses guide brackets to allow the fly section to move with ease on the base section. The D500-2 series does go up to 375lbs when using the ladder in that series under 32ft. Both style of ladders are considered heavier duty extension ladders.

Is this ladder comparable to the Model D13282 [250# limit], or is another current model more similar? I am looking for a similar quality ladder.

Asked by: Anonymous
The D524-2 is a 24ft 375lb rated extension ladder. For an aluminum 250lb rated extension ladder you will need the D1328-2 for 28', and D1324-2 for 24'.

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.
