Grooves help but don't eliminate the hazard - for oversized stair rails simply can't be grasped securely. If the horizontal profile of a stairway handrailing is too fat (we give an example below, thumb
Perimeter larger than 6" must have a graspable finger recess (see details at the ASM document link below). Rectangular shaped: perimeter must be between 4" and 6.25". Wood oblate shaped: <= 2.25" across widest dimension. Metal ogee shaped: <= 2.25" across widest dimension. Round rails: between 1.25" and 2" in diameter. Profiles & Dimensions of Graspable Handrailings Dimension Specifications for Graspable Handrails: recap It's not a great handrailing to prevent a fall.ĭefinition: Graspability of a handrail refers to the ability to get a secure hold onto a handrailing whose purpose, after all, is both to guide a walker along a stair or other surface and to prevent or perhaps to interrupt slip trip and fall hazards. Beautiful, this handrailing reflects the Moorish affection for water. Shown above/left: a water-filled handrailing along a stairway at the Alhambra in Spain. While graspability of handrails naturally focuses on the profile or shape and dimensions of a handrailing, the spacing of the handrail from the wall, its height, continuity, and other features also will interfere with the ability of a person to securely grasp a handrailing when she wants to or needs to in an effort to prevent or arrest a fall. If a railing cannot be securely gripped it is unsafe. The intent of a handrail is to provide a handgrip for people using a stairway. Hold On!
