MAKING LIFE EASIER - The rubber threshold ramp provides an easy and smooth transition, allowing those in need to get up and down the threshold safely and efficiently. Furthermore the integrated design of the threshold ramp 1.5 inch rise requires no assembly at all and can be easily cleaned. HIGH TOUGHNESS RUBBER - The threshold ramp is made of highly tough natural rubber with good resistance to compression, not easily deformed or corroded. It performs well in all seasons and climatic conditions. The rubber ramp has no pungent odour but a slight rubbery smell which is harmless to humans and the environment. ANTI-SLIP & DRAINAGE DESIGN - Threshold ramp surface is designed with anti-slip grooves to form drainage paths while increasing friction, effectively preventing slipping, falling and scratching.
