Type 1 Object Marker OM1-3

• MUTCD Type 1 object marker OM1-3, solid yellow
• .080" (80 mil) rustproof aluminum
• 3M retroreflective sheeting in your choice of grade
• Pre-punched mounting holes, rounded corners, no border per MUTCD
• Made in the USA

The OM1-3 is the all-yellow Type 1 marker: a borderless diamond covered edge to edge in yellow retroreflective sheeting, with no dots or reflector buttons. Use it on the face of an obstruction in the road, or at the start of a raised median, where a simple yellow diamond is enough.

It is cut to 18" x 18" with three sheeting grades to choose from. Diamond Grade DG3 returns the most light at night, and DG3 Fluorescent Yellow adds the brightest daytime color.
