This is designed for holding one 30 ml or 55 ml syringe when using LOCTITE® 3 or 4 axis robots. This C rail type connection allows for more than one bracket to be used when using 3 axis robots. This allows for multiple dispense points to increase throughput. A mounting rail (98328, 98329, or 98330);  plate or adapter (see 3 listed here) must be purchased separately to mount the brackets on the robot.
