The overall dimensions of ❶ height, ❷ width and ❸ length must fit within the amount of space that is available to install the crossover system. If you have enough room to install a crossover system with standard stairs, that is the OSHA-preferred solution.

The platform ❹ length and ❺ stair height are determined by the dimensions of the obstacle. These measurements are used to calculate the overall dimensions of the crossover system.

Optional accessories for alternating tread stair crossover systems

Safety gates

Safety gates provide additional security at the top of alternating tread stairs. They attach to the platform rails with reversible hinges and provide a 180° gate swing.

$319.10/gate: Carbon steel with standard powder coat colors
$329.75/gate: Carbon steel with hot-dip galvanized finish
$600.20/gate: Grade 304 stainless steel with mill finish

Backpans

Minimize the risk of damage to workers and equipment beneath your crossover system by adding backpans to the alternating tread stairs. Backpans bolt under the stairs to form a solid barrier behind the treads that spans the height of the stair and provides protection from falling objects.

Pricing for backpans is based on the stair height.
