Abstract: A golf putter head adaptor for providing a putter head with an elastomeric striking surface is provided. More particularly, the adaptor includes a central portion adapted to cover a substantial portion of the striking surface of a putter head, an upper lip portion adapted to engage the top surface of a putter head and a bottom lip portion adapted to engage the bottom surface of a putter head. The adaptor also includes an elastomeric portion associated with the central portion of the attachment layer such that it covers a sufficient portion of the striking surface of the putter head to allow the striking of a golf ball exclusively with the elastomeric portion of the striking surface. Also provided is a putter including the putter head adaptor and a snap-on putter head adaptor for providing an elastomeric striking surface to a putter head.
