Safety Flag RIB Fiberglass Rib for Roll-Up Signs

The Safety Flag RIB Fiberglass Rib for Roll-Up Signs is a replacement support rib engineered to hold roll-up safety signs rigid and upright in the field. Made from fiberglass, these ribs are available in 36" and 48" lengths to match the most common roll-up sign sizes used on jobsites and roadways, and can be ordered individually or in packs of 24 to keep crews stocked with spares. Whether you are maintaining existing roll-up sign stands or building out new ones, these ribs give the sign face the structure it needs to stay visible to approaching traffic. Each rib is manufactured by Safety Flag specifically for use with its line of roll-up traffic and safety signs, giving fleet and maintenance teams a reliable, drop-in replacement part.

Why Safety Flag?

Safety Flag builds these roll-up sign ribs from fiberglass to give crews a lightweight component that still holds its shape under repeated roll-up and deployment cycles. Offered in both 36" and 48" lengths and sold individually or in packs of 24, these ribs make it simple to keep roll-up safety signs properly supported and ready for the next shift on the road or jobsite. Each rib is designed as a maintenance part for existing roll-up sign frames, not a complete sign kit. From daily lane closures to larger work zone setups, these fiberglass ribs help keep Safety Flag roll-up signs performing the way crews expect.
