As featured in the Bison Catalog, Bison Inc. continues its expansion into diamond sports with the launch of its Foul and Fair™ Pole Series. Engineered for recreational fields, high school athletic complexes, and collegiate ballparks, this heavy-duty pole system delivers professional-grade outfield boundary visibility with reduced installation and freight overhead.
Built with the same heavy-duty fabrication, wind-load resistance, and safety-first engineering that define Bison’s industry-leading basketball, soccer, and volleyball lines, the Foul and Fair™ line provides a reliable, long-term solution for facility directors and grounds crews.

Modular Design: Reducing Freight and Installation Overhead
Traditional one-piece foul poles present significant shipping and handling challenges, often requiring specialized long-bed freight transport and heavy crane machinery for field installation.
Bison solves these logistical hurdles with a precision modular multi-section design:
- Reduced Freight Costs: Ships via standard commercial carriers, significantly lowering transit costs compared to rigid one-piece poles.
- Simplified Jobsite Handling: Modular sections allow ground crews to maneuver and position hardware on-site without heavy machinery or specialized rigging equipment.
- Seamless Assembly: Precision-machined connections ensure absolute vertical alignment, structural rigidity, and uniform aesthetic continuity once erected.
Wind-Load Engineering & High-Visibility Construction
Outfield boundary structures must withstand intense ambient wind loads and severe seasonal weather without leaning, rusting, or suffering weld fatigue.
Key Technical Specifications:
- Material Selection: Available in heavy-gauge structural steel for maximum rigidity or non-corrosive rustproof aluminum for coastal or high-humidity environments.
- Wind-Dissipating Wing Design: Features 16-inch wide welded expanded metal wings that allow high-velocity wind to pass freely through the structure. This significantly reduces wind drag, preventing foundation stress and pole deflection during storms.
- High-Visibility Polyester Finish: Coated in a heavy-duty, UV-inhibited optically vibrant yellow polyester powder coat engineered to resist chalking, fading, peeling, and rust under intense sun exposure.
- Official Field Pair Packaging: All Bison Foul and Fair™ Poles are sold and shipped in complete field pairs (left and right field lines).
Flexible Mounting Configurations for Any Facility Layout
Field conditions and municipal building codes vary across park complexes. The Foul and Fair™ series supports three distinct footing engineering options:
- Direct-Bury Footings: Permanent in-ground concrete installation for traditional field construction.
- Pedestal Base Mounting: Surface-mounted flange base designed for bolting directly to pre-cast concrete piers or footings.
- Semi-Permanent In-Ground Sleeves: Utilizes ground sleeves to allow seasonal removal for multi-use fields or winter storage.
