What is threshold ramp?

What Is a Wheelchair Threshold Ramp? A wheelchair threshold ramp is a simple and safe way to help wheelchairs cross over rough surfaces. They provide a sturdy, slightly-inclined platform to make it easy to cross over raised landings, doorways, or curbs. They can be used in doorways, small steps, or raised curbs.

How is threshold ramp measured?

How to Measure for a Threshold Ramp

  1. Measure the rise of the threshold. The first measurement to take is the rise in inches from the walking surface to the top of the door’s threshold, landing, or step where the ramp will be used.
  2. Measure the width of the door or entry.
  3. Measure how far the ramp can extend from the door.

What is the minimum gradient for a ramp?

A gradient of 1:15 is often required by social services and local authorities for public access situations, for example schools and libraries. More commonly however, a gradient of 1:12 is required for residential situations, and is also the minimum gradient required by building regulations for installed ramps.

What is step ramp?

Step ramp: like a kerb ramp but not attached to a kerb. It might assist someone to ascend a small step (no more than 190mm) in a store but can’t be longer than 1900mm or steeper than 1:10. It must have a slip resistant surface. Threshold ramp: a short slip resistant ramp which allows access to a doorway.

What size threshold do I need?

Measure the space between the outside edges of the door casing. The new threshold should have a similar profile to your old threshold and be 1- to 2-inches longer than the length of the doorway so that you can trim it for an exact fit.

How wide should a threshold be?

The height of thresholds can vary anywhere from 1/4″ tall to 1″ or more. ADA requirements may restrict the height of the threshold to 1/2″ tall and a gradual incline no greater than 1/4″ in vertical rise. Thresholds can be supplied in widths from as small as 2″ wide up to 10″ or more.

What is the maximum gradient for a ramp?

However, ramps should always be considered before installing steps. Ramp design the recommended maximum ramp gradient is 1:20, although • steeper gradients of up to 1:10 may be acceptable over short distances; the recommended minimum width of a ramp to • accommodate all types and abilities of user is 1200mm.
