DO YOU HAVE A LADDER THAT WOULD WORK FOR A ROOF ACCESS HATCH

Is there a way to measure exactly the distance between the wall and where the bottom of the ladder should be placed?

Asked by: Anonymous
An extension or straight ladder should be placed at a 4 to 1 ratio, of height of the ladder to distance from the wall. For every 4 feet high the ladder extends, the base of the ladder should be 1 foot from the wall. The ladder should be set up at a 70 degree angle for proper use.

Can this ladder be used in a vertical application if it is secured at top and bottom?

Asked by: Anonymous
The aluminum straight ladder model 518-1 is designed to be used at a 75 degree angle. Setting up the ladder at the proper angle will help reduce overloading and slip hazards.

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.
