Addition to any ball field, this pair of Professional Foul Poles clearly marks the difference between a home run and a foul ball. Players, fans and officials can make the call in any conditions, day or night, thanks to the bright yellow coating and expanded metal wings. Heavy-duty, powdercoat steel means the poles are built to withstand harsh weather and line-drive home runs. Constructed of heavy-duty 3.5” OD 13 gauge steel pipe with an 18” wide expanded metal wing. Bright yellow makes it easy to track the ball as it crosses past the poles.
