Thru-Hull Installation ToolĀ
Thru Hull Installation Tool
The Concept:
THT-530 makes the installation of standard GROCO thru-hull fittings possible by a single installer. Ā Slide the thru-hull fitting, flanged end first, over the tool. Ā (It will stop at the proper step.) Ā Tie a length of monofilament to the eye and place it into the already-cut hole in the hull of the boat. Ā Apply caulking to the flange of the fitting, and pull the fitting through the hole and against the hull from inside the boat. Ā Thread the mono-filament through the locknut or seacock. With the fitting pulled firmly against the hull the locknut or the seacock may be screwed onto the fitting.
THT-530 fits GROCO Thru-hull Fitting Sizes from 1/2" through 3"
