Ronstan's Open Body Turnbuckles are made from polished chrome plated high grade brass bodies with grade 316 stainless steel end fittings to avoid excessive thread wear or seizure under load and to make adjusting the rig tension easier. The brass body withstands up to 47% and 71% more tension than competitors' brass or stainless steel turnbuckles.
Ronstan's turnbuckles require less torque to adjust. The toggles are designed with full universal movement for easy installation and connection and allow the assembled cable to move where the structure is subject to wind loads or vibration. This one swages to a 3/16 in.-1/4 in. (5-6mm) and terminates with a toggle that requires a 3/8 in. (9mm) pin. The thread size is 3/8 in. (9mm).
