Description
Description

Utility ramp handrails are common all-in-one safety components used along any accessible ramp that typically provide user assistance and protection from falling off a ramp. As free-standing elements, utliity handrails must double as both an assistive handrail and a guardrail that prevents users from accessing the edge of the ramp. For edge protection, utility handrails must include either curbs or barriers at a minimum of 4” (10.2 cm) high along the ramp edge, or an integrated parallel bar at the bottom of the handrail that would restrict the passage of a 4” (10.2 cm) diameter sphere.

Dimensions & Sizes
Dimensions & Sizes

The Ramp (Handrails - Utility) has an overall combined height of 4’ (122 cm), total length of 18.7’ (5.7 m), and width of 44” (111.7 cm). Dimensions will vary based on the desired slope and height needed. Handrails along both sides of a ramp are required on any ramp system with a rise greater than 6” (15.2 cm) or a horizontal run greater than 72” (182.9 cm). The top grippable surface of any ramp handrail must be set at a height between 34”-38” (86.4-96.5 cm) above the ramp surface and a minimum clear width of 36” (91.4 cm) must be provided between handrails. In situations where a handrail is not continuous, handrails must extend at least another 12” (30.5 cm) parallel to the flat surface of the ramp landing. Inner handrails on a switchback or turned ramp must always be continuous. The ends of any handrail should be rounded or returned smoothly to the floor, wall, or post.

ADA accessible ramps must maintain a minimum clear width of 36” (91.4 cm) at all times. The cross slope along the width of any ramp must be less than 1:50 or <2%. The 36” (91.4 cm) clear width must be maintained between all including handrails.

The maximum allowable slope in any new construction is 1:12 with a maximum rise of 30” (76.2 cm) without a landing. A ramp with a slope between 1:12 and 1:16 can have a maximum horizontal length of 30’ (9.14 m) without a landing. A ramp with a slope between 1:16 and 1:20 can have a horizontal run up to 40’ (12.19 m) before requiring a landing.

Common Questions
Common Questions
What is the amount of edge protection required along a ramp?
To prevent users from slipping from the ramp edge, a continuous 4” (10.2 cm) high curb or lower guardrail must be provided along the ramp.
How should a ramp railing finish?
If handrails are not continuous they must extend at least another 12” (30.5 cm) parallel to the flat surface of the ramp landing. The ends of any handrail should be rounded or returned smoothly to the floor, wall, or post.
How high should a ramp handrail be?

Ramp handrails should have their top surfaces set between 34”-38” (86.4-96.5 cm) above the ramp surface.

Ramps are inclined surfaces that join different levels of a space. Commonly used at the entrances of buildings to accommodate level changes, ramps provide building access to wheelchair users. The maximum slope of a ramp is calculated to provide comfortable and easy access to the building.
