The 6-in. High Rocker Adapter Plate for Thick Stock Gluing Applications is now available for all JLT Panel Clamp models. Custom shops that face glue up to 6-in.-thick material can outfit their JLT Panel Clamp with this simple accessory. Rocker plates are designed to fit over existing clamp arms and offer a pivoting feature to guarantee a better glue joint. The rocker adapter helps woodworkers produce more butcher block, tabletops, turnings and many other thick stock glue ups, the company says.
