Safety Chuck Synopsis

Double E offers sliding safety chucks because they’re safer, easier to operate, and more rugged than tilting designs. The safety chuck slides open with a patented push–button mechanism, but only in the upright position, so roll security is guaranteed. The safety chuck closes automatically if operator forgets to close it manually. Safety chucks can be flange-mounted or foot-mounted, fixed or with sidelay adjustment.
