Thru-Hull Installation Kit

Part #: Z2002
Whether you make your own or use our convenient kit, always use plywood backing blocks to reinforce the hull when you install a thru-hull.
Saturate the blocks with the supplied epoxy. Next, mix filler into some epoxy resin to make a thick paste. Bond the block to the hull using the paste. Finally, seal the fitting to the hull using the supplied sealant.

Installs two 3/4" thru-hull fittings commonly used in Catalinas for sink drains as well as upgraded scupper thru-hull plumbing.
