A STAIR RAIL IS A GUARD ALONG THE OPEN SIDE OR SIDES OF A STAIRWAY.IT IS A SAFETY RAILING OR BARRIER LOCATED ALONG THE OPEN SIDE(S) OF A STAIRWAY.
THE BUILDING CODE REQUIREMENT FOR STAIR RAILINGS TYPICALLY REQUIRES STAIR RAILS OR STAIR GUARDS (AND ALSO HANDRAILINGS) ON STAIRS THAT HAVE A TOTAL RISE OF THREE FEET OR MORE.
Stairways with four or more risers or rising more than 30 inches (76 cm) in height- whichever is less- must be installed along each unprotected side or edge.
Top edges of stair rail systems used as handrails must not be more than 37 inches (94 cm) high nor less than 36 inches (91.5 cm) from the upper surface of the stair rail system to the surface of the tread. (If installed before March 15, 1991, not less than 30 inches [76 cm]).
Stair rail systems and handrails must be surfaced to prevent injuries such as punctures or lacerations and to keep clothing from snagging.
Stair rail systems and handrails must be surfaced to prevent injuries such as punctures or lacerations and to keep clothing from snagging.
Ends of stair rail systems and handrails must be built to prevent dangerous projections, such as rails protruding beyond the end posts of the system.
Intermediate vertical members, such as balusters used as guardrails, must not be more than 19 inches (48 cm) apart. Other intermediate structural members, when used, must be installed so that no openings are more than 19 inches (48 cm) wide
Examples of Stair Rail or Stair Guardrail Safety Hazards
Railing wrong height on stairs (above) or landing (at left) - too low to grasp or too high to grasp, or too low to prevent falling off of a platform, as I'm demonstrating in the right-hand photo above and in the stair landing photo shown here.
Railing loose, not properly secured (litigation photos)
Railing missing
Railing wrong dimension - cannot grasp; railing does not permit continuous grasping over length
Types of Railing Systems
There are many Types of Railing to choose from. Flat, Sloped, Stair, Arch'd, Arch'd-Stair & Double Arch'd-Stair Railings drawn together or separately.Railing types:Picket in 2-line, 3-line, 4-line, Decorative, StairGlass in 2-line, 3-line, 4-line, Clipped and even Structural.Custom in Panel, Basket (bellied), Cable, Mesh or Multi-lateral.Wall rails Single or Continuous (also matched sets for all the above designs to!)(Railings can be with or without grab-rails on either side)
