About this file
This is a product specification document for #930 polyester barrier netting, related to the DeLaveaga Golf Course Range Net and Chain Link Replacement project in California. The project involves replacing approximately 970 linear feet of golf range netting that was installed in 1999 and has exceeded its expected ten to eighteen-year product lifespan due to ultraviolet light exposure, wind, and weather deterioration. The specification details the LFS Sports & Industrial Netting #930 or approved equivalent product requirements, which includes 1-inch mesh size knotless netting with 116.7 pound average single mesh break strength, UV-treated yarn with resin dye and bonding treatment, and a weight factor of 40 square feet per pound. The netting system shall also include 3/8-inch braided black perimeter rope with minimum 3,500 pound breaking strength, internally constructed vertical and horizontal ropes, #48 braided polyester twine with minimum 375 pound tensile strength for attachment, and 9/32-inch cadmium plated steel carabiner attachment snaps with minimum 1,140 pound breaking strength. The project scope additionally encompasses relocation of existing cables and hardware, installation of new hardware, removal and replacement of 1,170 linear feet of 4-foot chain-link perimeter fence, repair of two access gates, and disposal of all removed materials, with the driving range expected to remain closed during construction.
The netting system is accompanied by a ten-year manufacturer's warranty and is available from LFS, Inc. in Bellingham, Washington, or an engineer-approved equivalent. Mesh break strength has been determined by independent laboratory testing per ISO 1806 methodology, with testing reports available upon request. The specification requires that all net panels be custom fabricated to as-built measurements to provide taut panels upon completion, with attachment twine tied via clove and one-half hitch knots spaced a maximum of 8 inches on center and suspension snap-to-cable attachment points not exceeding 3 feet on center.

Specifications
LFS #930 polyester golf range netting with average 116.7 lb. mesh breaking strength, 2 ½” stretched mesh; 1” single bar measure, four needle raschel knotless construction, manufactured with U.V. treated yarn and additionally coated with a black resin dye and bonding treatment. Mesh break strength determined by independent laboratory per ISO
1806.
All sections of netting component to be constructed to a 3/8” braided black perimeter rope, minimum 3,500 lb. breaking strength. Additionally, net panels shall have internally constructed vertical and horizontal ropes of the same material. All rope locations on the net panels shall correspond to the as built net panel suspension and support cables constructed to pole structures. All net panels shall be custom fabricated to as built measurements of the pole/cable structure to provide a taut panel upon completion.
Attachment of net and rope components shall be made with #48 braided polyester twine, minimum 375 lb. tensile strength, treated black. The attachment twine shall continually encompass the netting component and be tied to the rope component via a clove and one half hitch knot +/- 6 inches on center, never to exceed 8 inches on center.
Finished net panels shall be suspended to cables by the rope component via a
9/32”cadmium plated steel carabiner attachment snap, minimum 1,140 lb. breaking strength. The interior of the snap shall encompass only the rope and cable components when suspension is completed. The interval between snap to cable attachment points shall not exceed 3 feet on center (snap size may vary to fit cable size(s) specified).
Netting system shall be accompanied by a ten year manufacturer’s warranty. Netting system is available from LFS, Inc., Bellingham, WA, 800-426-8860, or engineers approved equal.
Ten year warranty. ²
1.). Mesh strength based upon most recent independent lab testing reports. Report copies are available upon request. Testing conducted per ISO 1806 methodology.
2.). Some exclusions and limitations do apply. Warranty document is available upon request.
