I have installed the through-hull as a cockpit drain, works perfectly, water can only flow in one direction

Good product that looks good

Produit répondant aux attentes, bien fini, clapet anti-retour fonctionnel

When the execution came to me, I thought first, she was broken. Because the cap hung crooked and was only secured with half screwed-in screws. In fact, however, the cap is removed during installation and mounted only after insertion. Since "below" is usually in a different location afterwards, you can not use the four provisional holes. That's why I as a manufacturer (or SVB) would supply the parts individually. By the way: against splash water, the membrane will help, as a check valve the part is not really good because it is due to the design a little bit open.
