Instructions for use

Turnbuckles must be used for in-line applications only. Special attention should be paid to prevent overloading.
During tensioning, avoid forces on the turnbuckle that may lead to deformation. Should a turnbuckle start to
deform, the tension should be decreased immediately and any deformed parts should be replaced. Should
extreme circumstances or shock loading, possibly occur during use, this must be taken into account when TURNBUCKLES
selecting the correct products to be used for the application.

®
For the rigging of wires, ropes, rods etc., Green Pin turnbuckles are recommended to be used. The WLL
should be applied in in-line lifting only and overloading is not permitted. Nor should side loads be applied,
as the products have not been designed for this purpose.
Open body rigging screws are used for tensioning wires and ropes for less demanding applications
(for example rope railings).

Turnbuckles must be regularly inspected in accordance with the safety standards and regulations given
in the country of use. This is required because the products in use may be affected by wear, misuse,
overloading etc. which may lead to deformation and alteration of the steel structure.

Safe use of turnbuckles

Turnbuckles should be inspected before use to ensure that:
• all markings are legible;
• the threads of the body and the end fittings are of the same type;
• the pin, nut, cotter pin or any other locking system cannot vibrate out of position;
• the threads of the body and the end fittings are undamaged;
• the body and end fittings are not distorted or unduly worn;
• the body and end fittings are free from nicks, gouges and cracks.
Make sure that the end fittings are correctly screwed into the body. Always use the locking nuts provided to
prevent the turnbuckles from unscrewing. Never replace an end fitting by anything other than one designed
for the purpose, otherwise the turnbuckle may not be suitable for the loads imposed.
