Similar to Standard Foundation Tensioners, Elliptical tensioners were designed specifically for foundation fastening applications on wind towers, and utilize the existing hex nut as a reaction point in order to eliminate thread fit misalignment. Unlike Standard Foundation Tensioners, Elliptical tensioners feature an elliptical geometry, which enables fit in narrow access foundation applications without reducing load capabilities.

Operators may access the nut with a Tommy bar rather then employing the use of an offset rundown gear. Although these run-down gears offer advantages in some applications, when used in foundation applications, they are susceptible to damage caused by the ingress of debris. Elliptical tensioners are ideal for close clearance applications, or as a universal tool that will work in nearly any foundation application, whether standard or close clearance.

• Versatile design is compatible with Williams, Dyson, McAlloy and similar studs.
• Elliptical shape provides easy access in difficult, narrow access applications.
