Weather resistant

Is this ladder weather resistant? Comparing to model 6212 and unsure the difference between the two.
Asked by: Chris
Our fiberglass ladders are not weather resistant. Even though they are made of fiberglass, the ladder still has several steel rivets which can rust if exposed to the elements. This would also apply to the 6212 as well.

If a twin ladder has a load rating of 375 LBS, is this per side or total?

Asked by: Quagmire
Twin step ladders are rated with a per side load rating. The maximum load rating of each side should never be exceeded. The NXT1A12 Fiberglass step ladder is a single sided step ladder, and the rear of the ladder should never be climbed.

How can you identify the age of a ladder?

How can you identify the age of a ladder? Does the Mark indicate a date of manufacture?
Asked by: Gee
On each of our ladders you will find a date code stamp that will tell you the age of the ladder. On fiberglass step ladders the date code stamp is located on the underside of the bottom step. The first 4 digits will tell you the month and year the ladder was manufactured.

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.
