The H-114P is a customer-installed panel mount adapter designed for 3/8 inch square multiturn potentiometer models, specifically compatible with 3290 H or W style trimmers and RT24/RTR24 models. It features a 10-32 UNF-2A threaded bushing with a maximum panel thickness of 3.3 mm (0.13 inches) and includes an adjustable slot measuring 0.243 inches long by 0.064 inches wide by 0.064 inches deep for shaft alignment. The adapter is supplied with a lockwasher and mounting nut, with a recommended panel hole size of #7 drill (0.200 inches diameter), and includes an optional anti-rotation nub. This panel mount solution provides maximum design flexibility for retrofit applications, allowing customers to add panel mounting capability to existing trimmers without factory installation.
