D1328-2 28 ft Type I Aluminum D-Rung Extension Ladder is rated 2.7 out of 5 by 3.
Rated 4 out of 5 by from This ladder works well for around the house use. I own a Werner Extension Ladder. Model D1382-2 I need to replace the rope. What length should i buy?

Rated 1 out of 5 by from can not bring it down because the flippers are plastic the plastic flippers catch on the steps so they won't slide past so you can't bring the ladder down. needs metal flippers. bad design.

Rated 3 out of 5 by from Good ladder, bad rope. This is a good ladder, and as a roofer for the last 25 years I know a thing or two about ladders. The main problem is that when lowering the ladder, the rope tends to track off of the pulley get stuck between the pully and the bracket that holds it to the rung. You are left to either "walk" it down with it stuck in an extended position or push it up to the next rung, lean it in and climb up to the pulley and unjam it. This has been a problem since I bought the ladder, and has happened with nearly all the Werner ladders I have purchased. I seem to remember back in the day that the pulleys were made of METAL, not plastic.

Need to replace the ropes on a D1328-2 ladder. Can you provide rope routing and method to attach to the second or "fly" ladder?

Asked by: Steve S
The part number for the rope is 30-1. The pulley is attached to the base section then the rope comes down and is tied off to the bottom rung on the fly section.

How many rungs need to overlap when the ladder is fully extended?

When my 28' ladder is fully extended, only three steps overlap. Is it safe to climb at that limit, or should 4 of the steps overlap? Appreciate any advice. Tim
Asked by: Tim
When fully extended there should be three rungs from the fly section that will overlap the base.

My roof gutters are 28' above ground level. Can I use a 32' extension ladder for gutter cleaning or do I need a 36' ladder?

I'm trying to compare the actual ladders weights, not load capacity.

After 25 years it's time to replace my 24' type 1A fiberglass extension ladders. Borrowing a 28' type 1 aluminum was eye opening as to the weight difference. Where can I compare how much each ladder weighs?
Asked by: Dave the window cleaner
You can go to the following website and see the model numbers for the 28' aluminum extension ladders: http://www.wernerco.com/us/en/products/climbing-equipment/extension-ladders?ipp=24&cp=1&sort=default&tts=1467999705019 To see the detailed information on the ladder, click on view details. You will find the shipping weight under specifications.

I have a D1332-2. Can I use either the PK70 or PK 80? What is the difference between the two?

Asked by: Don
The D1300-2 series Aluminum Extension Ladder can use either the PK70-1 or the PK80-2 ladder levelers. The PK80-2 Level Master is an automatic leveler where both legs will adjust to height by setting the ladder on the ground. Installation requires the feet of the ladder to be cut off by using templates to mark the leveler location. The leveling feet become the permanent feet of the ladder. Please see the link below for further information. http://us.wernerco.com/en/view/Products/Climbing-Equipment/Accessories/PK80-2/PK80-2 The PK70-1 LevelLok Levelers have two base units, one attaches to each side of ladder, and the leveling foot can be used on either side as needed. The ladder will keep original feet, but use the leveler on each side as needed. http://us.wernerco.com/en/view/Products/Climbing-Equipment/Accessories/PK70-1/PK70-1

Separate base from fly on ext ladders and safely utilize?

Can all of your aluminum extension ladders be separated (base from the fly) and safely be used individually? Are there only certain ladders (5 star vs 3 star for example) in which this practice is deemed acceptable?
Asked by: Camsaw
Not all Werner extension ladders may be separated and used as individual ladders. Certain ladders may be separated and used as the base section only, while some the base and the fly section may be used separately. Only some Type IA and Type IAA may be used in this manner. To use the fly section as a single ladder, the ladder must meet codes for a straight ladder, as well as have the proper slip resistant shoes. All instructions for how to properly use the ladder, and which ladders may be used separately are labeled on the side of the ladder.

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.
