Abstract: A form is provided for constructing a jump pit with a sand area. The form is constructed in sections. Each section has an inside wall and an outside wall. A support member is located between the outside wall and the inside wall. The sections are secured together onsite. Caps are mounted on the support members. The caps include an inclined surface which slops upwardly and away from the sand area forming the inclined surface. A cover over the sand area is supported by the inclined surface. Optionally, a chamber is located adjacent the outside wall. A grate covers the chamber and the grate is supported by a brace. A mat covers the grate. Openings in the grate and in the mat permit sand through them, thrown from the sand area to drop into the chamber.

Abstract: A communications box for use beneath the surface of a track or artificial turf in an athletic field. The communications box has includes a base two major sides, and two minor sides. A partition is located between the major sides and generally parallel to the minor sides. The partition is secured to partition brackets. A cover bracket is located below the top edge of the major sides. Stud nuts are affixed to the outside of the major sides and minor sides. Stud bolts which engage the stud nuts retain the cover bracket and the partition bracket in place. Bolt holes for the stud bolts in the cover bracket are in pairs to permit the partition and the cover bracket to be raised and lowered for use with a turf cover under artificial turf and with a track cover under a track.

Abstract: A communications box for use beneath the surface of artificial turf includes a container having a peripherally-extending upper edge. A first resilient flexible seal extends vertically from and along the peripherally-extending top edge of the container. A cover includes a peripherally-extending edge, and at least one hand hole extending through the cover. A second resilient flexible seal extends vertically from and along the peripherally-extending edge of the cover. The cover and the second flexible seal are sized to be received within the first flexible seal extending from the peripherally-extending top edge of the container, and the first and the second resilient flexible seals prevent material from falling into the communications box when the cover is removed from the container. Seals may be provided around the hand hole and a lid receivable in the hand hole.

Abstract: A communications box is provided for use beneath the surface of either a track of artificial turf in an athletic field. The communications box has a base and two major sides which are the same size and parallel to one another and two minor sides which are the same size and parallel to one another. The major sides are larger than the minor sides. A partition is located between the major sides and generally parallel to the minor sides. The partition is secured to partition brackets. A cover bracket is located below the top edge of the major sides. Stud nuts are affixed to the outside of the major sides and minor sides. Stud bolts which engage the stud nuts retain the cover bracket and the partition bracket in place. Bolt holes for the stud bolts in the cover bracket are in pairs to permit the partition and the cover bracket to be raised and lowered for use with a turf cover under artificial turf and with a track cover under a track.
