In this blog will take a look at Turnbuckle types, common applications, and installation instructions so you can get started utilizing this convenient tool.
Types
The most common turnbuckle types are eye and eye, hook and hook, jaw and jaw, jaw and eye, and hook and eye, each named for their combination of end fittings. The fittings are determined by what the turnbuckles need to connect to and whether the solution is permanent or temporary.
Eye and Eye
Each end of the eye and eye configuration has a closed-loop teardrop fitting, and it can be used almost anywhere. The eye and eye turnbuckle is designed to accept a shackle on each end, with the shackle pins passing through the turnbuckle eyes.
Hook and Hook
Because they are simple to connect and disconnect, hook end fittings are commonly used to make temporary connections. However, because the hook configurations lack a safety latch, they should never be used in connections where tension may unexpectedly release.
Jaw and Jaw
A jaw end fitting is made up of a U-shaped jaw and a bolt that are held together by a nut or pin. This configuration allows you to connect the sling or lifting lug to the turnbuckle directly. Furthermore, it is useful for connecting components that cannot be opened, such as an eye bolt.
Hook and Eye
Similar to hook and hook, the only difference in this configuration is that the eye end allows for one secure end attached to the rigging hardware.
Jaw and Eye
The jaw and eye configuration is almost identical to the eye and eye configuration, with the added flexibility of connecting directly to the lifting lug.
Unless you have a fixed point or a lug that is difficult to work on a lift, this configuration isn’t as common.
