Handrail

A rail fixed along stairs, ramps, or walkways that people grasp for support and balance while moving.

Guardrail: A barrier that prevents people from falling from an elevated edge. A guardrail blocks falls; a handrail primarily supports the hand during movement.
Accessibility: The design of environments, products, and services so people with varied abilities can use them. Handrail placement and shape can determine whether a route is usable by people with mobility limitations.
Grip strength: The force produced by the muscles of the hand and forearm when grasping an object. A handrail lets users apply grip force to steady or arrest their movement.
Balustrade: A row of small posts supporting a rail along a stair, balcony, or other edge. A balustrade is an edge-guarding assembly that may include a handrail but is not the graspable rail alone.
Staircase: A structure of steps connecting different elevations. Staircases are a common setting where continuous graspable support matters.
Building code: A set of enforceable rules governing building design, construction, and safety. Building codes specify when handrails are required and set limits on their dimensions.
Friction: The force that resists sliding between surfaces in contact. Friction between the hand and rail helps prevent the grasp from slipping.
Bannister: A rail, often supported by posts, running beside a staircase. Bannister commonly names a stair rail assembly, while handrail emphasizes the part meant to be grasped.
Ramp: An inclined surface connecting elevations without steps. Ramps use handrails to support balance along a sloped route.
Americans with Disabilities Act: A United States civil rights law prohibiting disability discrimination in areas including public accommodations. Its accessibility standards set handrail requirements for covered routes and facilities.
