De-sta-co FL-121/45 Straight Line Action Clamp 3000N

Product Description

The DE-STA-CO FL-121/45 is a variable stroke straight line action clamp rated for 3,000 N (675 lb) of clamping force. It uses hand lever actuation and is designed for one-hand operation, making it well suited for production fixtures, jigs, and workholding applications where speed and repeatability matter. The plunger is 12mm in diameter with an M6 thread and supports a maximum rapid stroke of 45mm and a maximum clamping stroke of 3mm. The flange mount base allows direct installation to fixture plates or machine frames. Industrial assembly technicians, toolmakers, and fixture builders are the primary installers of this clamp.

This clamp is used in industrial and manufacturing environments where consistent, repeatable part clamping is required. Typical applications include welding fixtures, machining jigs, assembly stations, and quality inspection fixtures. The one-hand lever actuation allows an operator to secure or release a workpiece quickly without setting down a tool or part. The variable stroke design accommodates minor workpiece variation without requiring clamp repositioning, which reduces setup time on repetitive production runs.

Key Features

• 3,000 N (675 lb) load capacity for firm, consistent clamping force
• Variable stroke design with 45mm maximum rapid stroke and 3mm maximum clamping stroke
• 12mm plunger diameter with M6 thread for secure workpiece contact
• One-hand lever actuation for fast clamp and release cycles
• Flange mount base with 6.5mm mounting hole diameter and 52mm hole spacing for rigid fixture integration
• Compact envelope: 153mm overall length and 68mm overall height

Compatibility

Designed as a direct-fit flange mount straight line action clamp for industrial fixtures, jigs, and workholding setups that require a variable stroke, hand lever actuated clamp with an M6 plunger thread and 12mm plunger diameter.

Installation Notes

Installation is typically performed by toolmakers or fixture technicians using standard hand tools. Before mounting, verify that the fixture plate material and thickness are appropriate for the 6.5mm mounting holes and the 52mm hole spacing. De-energize or lock out any associated equipment before installing or adjusting the clamp in an automated or semi-automated fixture. Do not exceed the rated 3,000 N load capacity, as overloading can damage the plunger thread or clamp body.
