This design offers unobstructed views between treads so you can see through the staircase. Stair risers treads. Stair risers are used in buildings of all shapes and sizes. Buildings codes have been created to control the minimum and maximum measurements of risers and treads.
An open riser staircase is one in which the rise a k a the vertical part of the step between each tread is open rather than closed. Steep stairs make climbing more tiring and dangerous while shallow stairs are awkward and inefficient for our human stride. On the other hand stair risers also cover up areas under the stairs that people sometimes don t want to see. Instead they may use solid side stringers that anchor the treads using metal connectors.
Risers can either be enclosed or left open as in deck stairs or basement stairs. Rise it is the vertical height between the risers. This kit can be used as is for a closed stringer staircase ends of treads are hidden by stringers. The board that encloses the back of the step is also called a riser.
