Roof Access Hatches

Alternating tread stairs are built to exact, vertical height. For roof hatches, the height is measured from where the top landing of the stair is flush with the finished surface of the roof to the lower, finished floor where the foot of the stair will be secured.

Alternating tread stairs going to roof hatches include options handrails, which are designed to fit within a standard 12″ hatch curb; they extend 5¾” above the top landing on steel stairs and 3¾” above the top landing on aluminum stairs.
