This larger version of the quick-change clevis is meant for larger blades, sinkers, and bottom bouncers. Lure builders can use it
on in-line, and bent wire baits. Per 25.
Been using these clevis pieces for the last year and they work great. Use with a bead and swivel, they make a nice slinder rig that can be weight adjusted on an as needed basis by adding a quick change snap and using eyelet syle sinkers.
