• Spring advance work support contacts workpiece as it is loaded into fixture
• Low pressure lock-up capability enables the use of machine tool hydraulic systems
• High rated support capacities allow for more compact fixture design
• Corrosion resistant materials, compatible with most coolants and environments
• Threaded and manifold air vent ports allow fixturing that prevents coolants from being drawn into the system
• Minimized deflection increases machining accuracy
• Multiple mounting configurations for design flexibility
