L.J. Enterprise wood jumps are produced from full-cut oak, white pine and pressure-treated yellow pine. These materials have traditionally provided versatility, mobility durability and beauty in the horse industry. To prevent warping, all lumber is air stacked or kiln dried.

Bases are pressure treated for stability. Mortise and tenon joints hold the oak crosspieces to the uprights. The wood is primed and painted in either oil-base polyurethane or exterior latex. Pressure-treated four by fours are drilled at three-inch intervals, routed to provide ease in handling and the tops are beveled.

For extra longevity, we use oak bases on most of our solid fillers. All schooling standards are assembled with carriage bolts, and wings are assembled with "U" bolts made and inspected in our own shop. Board planks are made of full-cut, 2" x 10" x 12' lumber carefully chosen for clarity and reinforced by 3/8" x 10" rod at each hanger for support.

The dimensions of our jumps have been chosen carefully so that they not only conform to AHSA standards but also are solid, practical and stable. For instance, L.J. Enterprise builds brush racks using 2" x 10" end pieces with pressure-treated oak bases for added stability. A dado cut allows for a recessed top board that is drilled for flowers. A green filler to fit inside each section of the brush rack is also available.
