Product Information
The Tusa Male Dive Fins Side Buckle (TC-305) is a genuine Tusa replacement buckle for the male side of a Tusa fin strap, finished in white, so a diver can repair a cracked, loose or broken strap connection instead of buying an entire new fin strap or a new pair of fins.
Who it is for
This buckle is for Tusa fin owners whose strap hardware has failed from age, sun exposure or heavy use in saltwater and chlorine. If the male side buckle on your fin strap has cracked or snapped off, the TC-305 lets you make a direct repair. It is a practical fix for travel divers, instructors and rental fleets that need to keep gear in service.
