Product Description
The RubberForm MLSB Series 2.5” and 3″ Dirt Road Speed Bumps are the perfect solution for any dirt road traffic calming needs. With help from industry experts, RubberForm has developed specially designed hardware options that allow our speed bumps to be safely secured to dirt roads and gravel roads for permanent or semi-permanent installation.
Each portable rubber speed bump features a dovetail design that allows unlimited custom connectivity. Choose the height you need to slow traffic to your desired speed – as slow as 3-5 mph. Manufactured with solid, masticated recycled rubber to withstand extreme temperatures, constant U.V. light, extreme weather conditions, and of course, high traffic volume.
These qualities make RubberForm’s Dirt Road Speed Bump the superior choice for guarded gate entrances or exits, construction sites, private facilities, or anywhere with dirt or gravel roads where an aggressive traffic control device is needed.
