Different types of ladders are designed to keep you safe and productive when climbing or standing. Always select a ladder that is right for the job and meets the required standards; if in doubt, select a strong product. Using the wrong style of ladder or simply ignoring the limitations of climbing equipment can result in a fall or serious injury.

Reach Height is the maximum reach calculated by adding the maximum standing height on a ladder plus the average height of a 1.75m (5'6") person.
The highest ladder standing point on an extension ladder is typically 4 rungs from the top and a stepladder without a platform is 3 steps from the top. On a platform stepladder, the highest standing point would be the platform itself.

Ladders are designed to safely hold up to a specific amount of weight. The load capacity is defined as the maximum safe load on 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 ladders are made from fibreglass, aluminium, steel & plastic. 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 fibreglass products due to their non-conductive stiles.
