MS21260-L4LH TERMINAL (Turnbuckle) is a swage-type wire rope stud terminal designed for aircraft flight control cable systems. This long-shank terminal features a left-hand 1/4-28 UNF thread and is intended for use with 1/8-inch aircraft control cable, providing a secure and adjustable connection within standard aviation turnbuckle assemblies.

The terminal is permanently attached to the control cable using an approved swaging process, creating a high-strength mechanical connection capable of withstanding the demanding loads encountered in flight operations. When paired with a compatible turnbuckle barrel and right-hand terminal, the left-hand thread allows precise cable tension adjustment during aircraft rigging, inspection, and maintenance procedures.

MS21260 series terminals are commonly installed in primary and secondary flight control systems, including aileron, elevator, rudder, trim, and other cable-operated mechanisms where accurate cable tension is essential for safe aircraft operation. The precision-machined design ensures proper fit, dependable strength, and long-term durability in vibration-intensive aerospace environments.

Manufactured to established military and aerospace specifications, the MS21260-L4LH terminal provides excellent dimensional accuracy and corrosion resistance. Proper installation requires approved swaging equipment followed by inspection in accordance with the applicable aircraft maintenance manual and regulatory requirements.
