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. They are easily adjusted by turning the unique coupling nut, which is free to rotate on the turnbuckle barrel, and are secured with a quick turn on the cone shaped locking nut. With single end adjustment and a fine thread, Type 1 turnbuckles are much easier to adjust than conventional turnbuckles, and the use of dissimilar but compatible metals for the threaded components avoids the risk of thread seizure. 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.
