Tire Conversion Technologies' ENVIROform Portable Sign Units are ideal for parking lots, crosswalks, guard booths, schools, malls, industrial and construction sites, or anywhere portable or temporary signs are needed.

The use of just one economical unit will provide enhanced vehicle and pedestrian safety and provide you with reduced liability/damage. This portable base makes parking lot maintenance and snow removal tasks easy.

One 60-pound sign base prevents more than EIGHT tires from entering America's landfills! 

USGBC (US Green Building Council) Recognized GREEN Product!

These bases are made from 100% recycled rubber and will not chip, crack or corrode.

The sign base may be used in both indoor and outdoor settings. 30 lb models are ideal for indoor or light temporary use. Each 60 lb. unit is stable enough to withstand high winds and bad weather, as well as heavy traffic areas. For excessive high wind areas, add a 30 lb. base to any octagon base, for additional stability.

These bases clean up like new with whitewall tire cleaner (no wiping required).

Available in 3 sizes:  

Small: measuring 18" x 18" x 3", weight: 30 lb.;

Medium: measuring 18" x 18" x 6", weight: 60 lb.; and 

Large (90 lb = a 60 lb base with a 30 lb extender).
