Here are some great examples of cable ladder risers in application on a project. Risers are fittings available for all sizes of steel, aluminium, and FRP cable ladder and allow for a 90 degree upward or downward curve as a part of the ladder installation. If you need to change the level of the ladder you are installing, you can use a combination of the internal and external types of risers to do this. Risers are manufactured in multiple arc radiuses, and are also available for any size cable laying width.
