SB10 is a large submersible eyeball fiber optic fitting designed for constant immersion in swimming pools, ponds, and water features. Constructed with durable stainless steel and a 1.02” (26mm) clear focusing lens, it provides underwater side-lighting from the mounting surface. The lens offers a 20°–40° focus range, while an o-ring and locking ring provide superior sealing against water ingress. Designed for flexible mounting via a backnut or separate backbox, it easily supports fiber sizes from 0.08” (2mm) to 0.31” (8mm). Featuring a wide 2.68″(68mm) flange, SB10 delivers reliable, highly accurate performance in demanding aquatic environments.
