Harmar Rubber Threshold Ramp: 3 in Rise
This page selects the 3-inch rise version of the Harmar rubber threshold kit. Measure the threshold at the route of travel and compare it with the assembled height before ordering.
Assemble to the measured height
The product listing describes a hidden dovetail system for connecting sections without tools, with 1/2-inch increments available by adding or removing pieces. Follow the instructions and verify that the assembled sections lock together and meet the floor and threshold securely.
Traction and opening clearance
The molded texture is described as slip-resistant for indoor and outdoor environments. Check that the ramp cannot shift, confirm door and track clearance, and make sure the device's wheels can pass over the resulting transition.
3-inch selection
3 inches is the selected rise. A verified load capacity is not stated in the available product page; check Harmar's current rating and usage guidance for the intended user and device.
