De-sta-co 630-R Straight Line Action Clamp 2500 Lb

Product Description

The DE-STA-CO 630-R is a standard straight line action clamp rated for 2,500 lb (11,120.6 N) of load capacity. It uses a linear plunger mechanism to apply direct in-line force, making it well suited for holding, pressing, and positioning workpieces in fixture and tooling applications. The round plunger travels 2 inches (50.8 mm) and features internal 3/8-16 threads for attaching a work contact or tip. The flanged base mounts through six holes and the straight red handle provides positive grip during actuation. A Toggle Lock Plus mechanism is included for added security under load. The unit is constructed from carbon steel and weighs 1.9 pounds.

The 630-R is used in manufacturing, assembly, and fabrication environments where a repeatable straight-line clamping force is required. Typical applications include welding fixtures, machining jigs, press tooling, and quality inspection stations. The flanged base format accommodates flat-surface mounting on fixture plates and weld tables. The 23:1 mechanical advantage when pulling and 36:1 when pushing reduces operator effort during repetitive clamping cycles. This clamp is installed by machinists, toolmakers, fixture builders, and automation technicians.

Key Features

• 2,500 lb (11,120.6 N) rated load capacity for heavy-duty workholding
• 2-inch plunger travel with internal 3/8-16 threaded tip for custom work contacts
• 23:1 mechanical advantage pulling and 36:1 pushing reduces actuation effort
• Toggle Lock Plus included for positive lock under sustained load
• Six-hole flanged base for rigid, flat-surface mounting
• Carbon steel construction for durability in industrial fixture environments

Compatibility

Designed as an OEM-style straight line action clamp for use in industrial fixturing, jig building, and workholding applications requiring a flanged-base, inline-plunger clamp rated at 2,500 lb.

Installation Notes

Installation is performed by toolmakers or fixture technicians using standard drill and tap equipment for mounting hole preparation. Ensure the mounting surface is flat and rigid to maintain clamping accuracy and rated load performance. Verify the plunger thread engagement length is sufficient for the work contact tip before applying full load. De-energize or lock out any associated automated equipment before servicing or repositioning the clamp.
