The Alpha® Quick Change Snail Lock Adapter is part of the Alpha® PVA QC polishing system, designed for use with low-speed polishers and PVA QC polishing pads. The system allows polishing pads to be installed and removed using a simple twist-lock motion, reducing pad change time during polishing operations.

The aluminum backer plate mounts to the polisher, while each compatible pad is equipped with a snail lock adapter. Pads lock securely into place with a short twist and can be removed just as easily when changing grits.
