How to measure your door frame for a modular ramp

To ensure a smooth transition between your door opening and modular ramp we manufacturer custom door plates to the exact measurements of your door frame. Before we can built your modular wheelchair ramp we require 3 measurements to ensure the plate fits correctly.

A: depth of door (wall to door frame)
B: width of door opening (frame to frame)
C: width of door opening (wall to wall)
