- Pre-punched 3/8" mounting holes in top and bottom for easy installation.
- Meets M.U.T.C.D. specifications for highway use.
See catalog page 9.
Roadside mounting suits cross-sections narrow enough that a shoulder panel stays within a comfortable sightline from both directions. Where width pushes it beyond that, R3-9a overhead is the correct specification. Both depend on continuous center-lane markings to convey the shared arrangement.
Available Reflective Finishes:
- Most common reflective finish used for traffic signs
- Meets federal minimum requirements
- 10 Year Outdoor Durability
- Brightest and most visible
- Exceeds federal minimum requirements
