The perfect solution to the troublesome task of installing a PL-259 connector on RG-58 A/U or RG-8/X coax. Shakespeare's revolutionary new centerpin connectors are solderless, fret-free, and botchless. They go on without a hitch, without soldering skills. No measuring, no critical stripping of coax insulation, no fussing with the coax's braid, and no tinning. Winner of industry awards for innovative design.
