A ladder frame is just that, a scaffolding frame built to be used like a ladder. In S-Style pattern, we have them available in sections 5' wide. One vertical half of these frames consists of a ladder-rung pattern, while the other half is mostly open space, none except the lowest rungs which extend all the way across the frame, as opposed to just half way. This area can be stepped through at height when navigating between sections. Although these scaffold frames have great climbability and are the best all-purpose frames, the impediment of having to step over their bottom rungs can be a reason somone might use the following frame on a larger job.
