Scuba_SI 39 Posted December 21, 2011 Hi All, I'm away from my office and gadgets, but want to get some spares to keep in the resort. Does anyone have a small bolt to hand that attaches a ULCS / INON ball adaptor to the handle in UW Housings? I'd like to know the size From memory i think it's M4 but i could be wrong. Thanks, Simon Share this post Link to post Share on other sites
