How to choose the best type of crossover stair for your application
More space? Choose standard stairs
Choose standard stairs for applications without space restrictions. They require more space to install than alternating tread stairs but they are also the most comfortable to use.
Less space? Choose alternating tread stairs
For applications where space is limited, choose alternating tread stairs. 68° alternating tread stairs require the least amount of space but the steeper angle is less comfortable to use. The less steep angle of 56° alternating tread stairs is more comfortable to use while also requiring less space.

What does OSHA say about crossover stairs?
OSHA classifies alternating tread stairs (alternating tread devices) as non-standard stairs and states they are acceptable to use in applications where it is not feasible to use standard stairs.
