Defined by building codes, handrails are in place to provide guidance, while the purpose of a guard(rail) is to prevent accidental falls. Handrails are located between 34” and 38” and by code, have dimensional limitations for grasp-ability. Guards are generally required for ramps, stairs or landings above 30” in height. The height of a guardrail will vary by code, but most commercial applications require a minimum of 42”. Always confirm the specifications of a railing installation with your local codes.
