Thru-hull threaded fitting

These plastic through hull fittings are threaded and are perfect for use as transom drains, finishing rings, console drains etc..

They are also suitable for use as bulkhead fittings, for example to bring cables or pipes through without a risk of snagging.

We recommend that these are fitted at least 6" above the waterline.
