This new sheave and shackle, or “bicycle wheel”, combination is designed to accommodate the special handling needs of pulling fiber optic cable. Among the unique features are a lightweight design, one-size shackle and the reduction of loose parts.
- Sheaves are lightweight aluminum construction with self-lube bearings
- Captivating pins on shackles prevent cable damage when not under tension
- For overhead applications 24 in. (61cm) sheave with shackle provides generous bending radius for fiber optic cable up to .6 in. (15mm) diameter
- All removable hardware is retained for security
