All Bison ShootOut soccer goals are constructed with special aluminum extrusions in either 4" round or 4" square with rounded safety corners and our exclusive torque tested backstay attachment system reducing the stress on vulnerable joints that often result in premature goal weld failure. Available in three sizes. All ShootOut soccer goals feature extra rear depth for reduced tip over risk and a rear horizontal stabilizer bar that can be positioned closer to the goal face for compatibility with football goal posts on shared sport fields. Nets attach easily with our QwikTrack net clip system.
