Laser etched calibration marks allow accurate, repeatable settings for precise adjustement and tuning of rig tension. Type 1 turnbuckles have a sleek, modern profile with no sharp edges.

Toggles are designed with full universal movement for easy installation and connection and allow the assembled cable to move where the structure is subject to wind loads or vibration.
