The Brutus HS is Gill's heavy-wind solution for high school discus facilities — built when a standard 2-7/8" pole cage isn't enough.

Available in 6-pole or 7-pole configuration and custom color options.

• 6-Pole or 7-Pole Configuration — Available in standard 6-pole layout or 7-pole design — the 7-pole configuration extends the net forward from the sides to comply with the 34.92° sector requirement while providing a less restrictive feel for throwers during approach and release

Gill manufactures this net to the precise specifications of the A8021 cage system, ensuring proper fit and consistent containment geometry.
