G'day,
Sorry if this is in the wrong forum .
Trying to source name and supplier of these gizmos...
Have tried searching: cleat, double cleat, sheave cleat, shock lock, shock cord cleat .
They are used often on shock cord or any small diameter cord to temporarily tie off / lock the cord.
This one has a "floating" cam lock wheel.
Prefer plastic / nylon if available.
Cheers,
Mark
