ScubaPro Twin Jet: Comes with the mating ScubaPro male side of the buckle (ScubaPro female side is attached to the fin).
These stainless steel fin straps come with a limited lifetime warranty and are available in 5 attachment styles. All styles are available with either the rubber "Comfort Grip" puller (provides heel cushioning and large grip for pulling straps on/off) or with black Tech Diver heel guard. Each style is available in 4 sizes.Grip-Tight: Fit most fin styles with the rubber attachment knob molded into the fins. Simply insert the solid cable wire into the knob holes and squeeze together with pliers.Older Twin Jet Fins have different female buckles mounted on the fins which do not mate with the newer male buckles installed on our spring fin straps. Our RB0521 4-piece replacement buckle pack is available to retrofit these fins with up to date female buckles which mate with our buckles.
