REPLACE
Replace a control line bridle as follows:
1. Place the canopy in proper layout on a repair surface; trace the control line bridle from one radial seam,
through the control line reefing ring, to the opposite radial seam.
2. Make a mark at the lower end of the two stitch formations; secure the original control line bridle to the
canopy.
3. Working through the canopy orifice ports, remove the original control line bridle by carefully cutting the
stitching that secures the bridle to the canopy at two points. Ensure the canopy fabric is not damaged
during the cutting process.
4. Cut a 6-foot length of type II, nylon cord, for use as a control line bridle, and wax the ends.
5. Make a mark at a point 6-inches from each end of the cord length.
6. Align the 6-inch mark on one end of the cord length, with one mark made is step 2., above.
