Roof Access Ladders

Due to modern designs most buildings have varying roof levels. Permanently fixed ladders allow workers to safely access these levels with ease.

Use a roof access ladder with a return when traversing walls, obstacles, or tall parapets.

Custom ladders are built for each installation location.

Our industrial ladders have a 20" rung width but can be custom sized anywhere between 16" and 24" as the project requires.

Rungs are attached with heavy duty, plug welded assembly.

Add on rung covers to increase tread in wet, oily, or icy conditions.



Ladder Cages

A ladder cage is required when the length of climb is 20 ft and greater above floor level.

Standard cage is 27" inside, but can be designed up to 30".

Sidestep for exit/entry onto platforms option is available.



When required, ladders are broken into sections for installation/shipping.

Hatch openings shall be provided with a means to facilitate access and exit from a fixed ladder (i.e. Grab Bars or other such items that can be grasped by the climber).

Ladder Security Doors

Adding security with anti-climb devices helps prevent unauthorized access to restricted areas.

We manufacture our doors in two styles: hinged, best for new ladders, and lift off, most often for retrofits which are sold as supply only as well. All doors are 7 feet tall.
