The Camco recycled rubber stabilizer jack pads help prevent jacks and stabilizers from sinking into soft ground. The flexible material is great for use on uneven surfaces such as gravel, tree roots and rough earth because it absorbs uneven pressure instead of cracking or wobbling. Recycled rubber stabilizer jack pads are UV-resistant, weather-proof and constructed of recycled materials. Nests ideally with Camco's 44595 jack pads.
