Locking-coaxial turnbuckle

Although the turnbuckle has been used for centuries, its evolution still continues. This short, in-line device uses coaxial male and female eyebolt fittings to reduce length and weight.

Providing adjustable latitude for applications with limited space, the device also has a locking system. After adjustment, two screws tighten the frame around the eyebolt shafts to inhibit rotation.
