How many different types of dual-action swivel clamp bases are used on current model stringing machines?
There are two types – those with spring-action levers and those without it. The dual-action swivel clamp bases that have spring-action levers are better, because they are both faster and much easier to use. Without the spring-action lever, the swivel base will occasionally catch the string. • Which stringing machines have a dual-action swivel clamp base with spring-action lever?
