Turnbuckles, type ПТР
Turnbuckles, type ПТР-7/60-1/2 provide smooth adjustment of the length due to the screw thread on the movable parts.

Depending on the direction of rotation, suspension set can be extended or shortened. After the desired length of the suspension set is achieved, turnbuckle screws are fixed by lock-nuts. Turnbuckles, type ПТР-7/60-1/2 meet the requirements of TU U 31.2-30255335-002:2006.
