【High Quality】The curb ramp is made of rubber which is very strong resistant to high pressure and has a long service life. Vehicular curb ramps are highly resistant to water cracks and deformation and can withstand prolonged exposure in bad weather. 【Large size】The size on a flat surface is 50cm×50cm×18cm/20×20×7in. This allows the car to safely drive up and down on uneven ground or surfaces on the side of the road. 【Anti-Slip Surface Texture】The non-slip tread pattern surface of the wheelchair ramp effectively increases the friction and enables the tire to easily run over the curb. The grid design of the ramp base maximizes friction against the ground adding greater stability. 【Prefabricated Holes】The sill car ramp is equipped with mounting holes for easy installation and you can use the integrated mounting holes at the bottom of the ramp to permanently install in high traffic areas. 【Multi-purpose】Portable curb ramps can be used for a variety of purposes. It is suitable for cars trailers wheelchairs walkers lifts trolleys motorcycles bicycles scooters and trolleys as well as driving on curbs or elevated sidewalks.
