Harmar Rubber Threshold Ramp: 2.5 in Rise
2.5 inches is the selected rise for this Harmar threshold ramp. Measure the elevation difference and inspect the available approach and landing before choosing this configuration.
Modular height adjustment
The listed kit uses hidden dovetail sections that connect without tools and can be assembled or removed in 1/2-inch increments. Confirm the completed assembly matches the measured threshold and follow the supplied instructions for interlocking the sections.
Surface and entry clearance
The molded rubber texture is described as slip-resistant for indoor and outdoor use. Make sure the ramp is stable, the door or track can move freely, and the wheelchair or other mobility device clears the transition without contacting the threshold edge.
