The Basewear duty rating is 300 lbs. This is the weight of the user and anything they are carrying or using. We do offer our Blue Armor1000 and 2000 in different sizes, which has a duty rating of 400 lbs. Please contact Customer Care at 888-523-3370, so we can discuss more in detail and confirm which harness will work for your needs.

Correct user manual?

Hi, the "Model H412002 User Guide" link on the main page for the BaseWear H412002 incorrectly opens a manual for a lanyard, not the BaseWear H412002 harness. Can you please fix the link so people can download the correct User Guide?

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.
