1. First, install the armor rods on the cable at the marker ball installation position. The required length is approximately 1000–1200 mm, with both ends extending 200–300 Hang the plastic clamp on the lower hemisphere onto the cable and secure it in place.
2. Attach the upper hemisphere onto the lower hemisphere (align according to the steel die marks on the clamp). Rotate until it is fully seated.
3. Finally, insert the M12 × 35 stainless steel bolts, then fit the flat washer and spring washer (secondary) in sequence, and tighten the nuts.
