The new heavy duty Big Gripper screen holding clamp is used with wood and metal frames of all shapes and sizes. The swivel locking clamp pad tightly grips square and round frames to insure rigidity. The Big Gripper pivots accurately because its bore is machined directly into its unique body design. Print repeatability and precise registration are assured. The Big Gripper Screen Clamp handles frames up to 3" high. The Big Gripper is used for single or multicolor jobs. Screens are securely mounted in the Big Gripper for exact repeatability and the best quality reproduction. Available per clamp or per pair, each Gripper mounts individually.
