Titan 779-078 Wing Knob Clamp

Wing Knob Clamp (779-078) for PowrLiner Series

The 779-078 wing knob clamp is a user-friendly fastening component designed for quick, tool-free adjustment on PowrLiner airless sprayers. It is commonly used to secure adjustable components such as handlebar height, guide arms, or accessory mounting brackets that require periodic repositioning. The wing-shaped knob provides excellent grip, allowing operators to tighten or loosen the clamp by hand without the need for wrenches or other tools. This design is particularly valuable in field conditions where quick adjustments are needed and carrying tools may be inconvenient.

The clamp assembly typically consists of a threaded stem with a wing knob, a clamping body, and often a captive washer or thrust bearing that allows smooth tightening. When the knob is turned clockwise, the clamp applies compressive force to secure the component in its desired position. Counter-clockwise rotation releases the clamp, enabling repositioning. In the demanding environment of professional painting, these clamps are subjected to repeated adjustment, vibration, and exposure to paint overspray and cleaning solvents. Over time, the wing knob can crack or become stripped, the threads can gall, or the clamping surfaces can wear, resulting in a clamp that no longer holds securely. A failing clamp can allow adjustable components to shift during operation, affecting operator comfort, spray accuracy, or equipment stability.

Replacing a worn or damaged wing knob clamp with the 779-078 assembly restores reliable, tool-free adjustability. The replacement clamp is manufactured to original specifications, with precise thread dimensions and a durable wing knob that resists cracking and provides comfortable grip. During installation, it is important to ensure that the mating threaded hole or stud is clean and undamaged. The clamp should be tightened firmly but not over-torqued, as excessive force can damage the threads or crack the knob. In applications subject to significant vibration, periodic re-tightening may be necessary to maintain secure clamping. For technicians servicing PowrLiner equipment, having the correct wing knob clamp on hand ensures that adjustments can be made quickly and that components remain securely positioned throughout the workday. This clamp is specifically compatible with PowrLiner 5500, PowrLiner 4955/6955/8955, and PowrLiner 4500 service models, making it the correct replacement for these popular units.
