The 10B5303 Box Anchors are recommended for natural grass fields, and adhere to the Kwik Goal Lock in to Goal Safety® program. The 10B5303 ground Box Anchors are attached to steel auger anchor pilings, which help with strength and longevity. A leash is run out of the box and around the base frame of the goal. The leash is then locked with a keyed padlock ensuring only authorized personnel can remove the anchoring. A soft urethane top protects the contents and minimizes disruption on the surface. The 10B5303 Box Anchors do not require concrete or excavation. 1 set of 10B5303 ground Box Anchors will secure one Kwik Goal soccer goal.
