a minimum opening of 61 cm when attached to the frame and the two forward cuts of the escape opening must not be less than 51 cm long from the points of the cut immediately forward of the TED frame. The resultant length of the leading edge of the escape opening cut must be no less than 142 cm stretched, or a double flap net triangular opening where the cut immediately forward of the TED must allow a minimum opening of 102 cm when attached to the frame with minimum forward cuts of 101 cm. The flaps must be composed of two mesh panels. Each panel must be a minimum of 147 cm wide and may overlap each other no more than 38 cm along the leading edge when stretched. The panels can be tapered two bar, one point so the flap overlap increases as they get closer to the bottom of the TED frame. The panels may only be sewn together along the leading edge of the cut and down the entire length of the outside edge of each panel. The trailing edge of each panel must not extend more than 61 cm past the posterior edge of the TED frame.

          (ii) a single flap rectangular net opening where the cut immediately forward of the TED must allow a minimum opening of 61 cm when attached to the frame and the two forward cuts of the escape opening must not be less than 66 cm long from the points of the cut immediately forward of the TED frame. The resultant length of the leading edge of the escape opening cut must be no less than 181 cm stretched, or a single flap triangular net opening where the cut immediately forward of the TED must be a minimum of 102 cm with minimum forward cuts of 136 cm. The flap must be a minimum of 338 cm by 132 cm piece of mesh. The 132 cm edge of the flap is attached to the leading edge of the escape opening cut. The flap may extend no more than 61 cm behind the posterior edge of the TED frame;

      (c) a maximum bar spacing of 120mm between bars; and

     (d) it is not permitted to attach any weights, chains or other devices on the escape flap which may prevent the flap from opening and

     (e) If the escape hole is in the bottom of the net, the following floats must be attached to the grid—
        (i) if the grid has a circumference of no more than 3050mm, at least—
 1.                  2 small floats; or
 2.                 1 medium float;
        (ii) if the grid has a circumference of more than 3050mm, at least—
