The D3/D holds a uniform D-shaped profile measuring 3" × 3-1/4" and is constructed of extruded EPDM rubber. EPDM is particularly well suited to outdoor applications due to its excellent resistance to weather, sunlight, ozone and water. It is used for a wide range of applications including loading docks, parking garages, marinas, vehicle and equipment protection, and industrial wall protection.
Note: EPDM has poor resistance to petroleum-based oils and fuels. Applications involving regular contact with gasoline, diesel, mineral oils or petroleum-based lubricants will shorten the product’s life span.
Benefits
- Installs easily — anchor bolts go straight through the pre-drilled holes into the dock or wall
- Eliminates costly and unsightly damage to equipment, vehicles and structures
- One-piece construction
- Made in the USA
- 1 year warranty
