Page 49 of the Rice Signs 2017 Traffic Safety Catalog details two specific folding-leg Roll-Up Sign Stands. The Single-Spring Sign Stand (catalog shows it as RU8000) features a wind spring for extra stability in windy conditions, MUTCD compliance, easy quick-latch sign holder, and compatibility with both 36 inch and 48 inch roll-up mesh signs and rigid pole-up aluminum signs. The No-Spring RU3000 Sign Stand uses telescoping folding legs without the wind spring, ideal for low-wind deployment scenarios and lighter signs — also MUTCD-compliant with the same quick-latch holder and dual-sign compatibility. Both stands fold compactly for vehicle storage and deploy in seconds with crew-friendly hardware.
