    Gridwire / Twine

    Gridwire can be suspended in various horizontal and vertical patterns to deter large aquatic birds. You can protect lakes, parking lots, warehouse roofs, etc. from gulls, geese, and other large aquatic birds.

    Polythylene Florescent GridTwine is more visible to birds than GridWire. This florescent GridTwine is intertwined with two strands of Stainless Steel wire for added longevity.

    Ferrules
    Use the copper ferrules with stainless steel cable, which works best for wet or salty climates. Two ferrules should be used per cable loop attachment. A special ratchet crimp tool is necessary.
  3. $67.95
    Crimping Tool
    Each cable-end must have a strong loop to secure to a turnbuckle or cable-end fastener. The powerful ratchet crimper and ferrules offer the strongest, most discreet system. Use two ferrules at each loop for long-lasting hold.

    Cable Support
    These poles can be used to build raised netting systems. The poles can be used to keep the center cable higher (like a tent) or to raise a whole net system above a flat roof, or a roof covered with HVAC equipment.

    The top of the pole has four holes designed to acommodate both perimeter net cable and turnbuckles. This flexibility allows the pole to accomodate a wide range of possible installations. The bolts half-way up the poles can be loosened to adjust the poles to the perfect height. By tensioning the cables equally in each direction, the flat base will simply sit in place. Protective neoprene pads insure no damage is done to the roof. Extend poles from 4.5 feet to 8 feet.

    Each pole includes one protective pad.
