The EM-Series Magnetic Holdfasts by Eclipse Magnetics deliver robust and versatile magnetic clamping and work-holding solutions, designed for welding, assembly, handling and fixture integration. With quick-action screw-release handles, and models offering up to 183 kg holding power, these units turn any ferrous surface into a reliable and adjustable anchoring point for production and fabrication setups.

Key Features

  • Compact magnetic holdfast units with screw-release handle for rapid engage/disengage. 
  • Four size variants available — model E939 to E942 — covering holding forces from 20 kg to 183 kg. 
  • Pre-machined fixing holes (PCD) for secure mounting into work holding or fixture frames. 
  • Durable build for industrial work holding, welding fixtures or assembly jigs.  

Typical Applications

  • Clamping work-pieces on welding tables, fabrication benches or machining fixtures.
  • Fixture integration in assembly lines to hold parts during bonding, riveting or inspection.
  • Magnetic anchoring of components in handling systems, transport or positioning setups.
  • Use within modular work holding frames where quick repositioning of hold-points is required.
