De-sta-co 81L12-10100 Pneumatic Hold Down Toggle Clamp

Product Description

The DE-STA-CO 81L12-10100 is a pneumatic hold down toggle clamp designed for vertical-mount fixturing and workholding applications. It operates on compressed air through an M5 port, accepting supply pressure from 20 to 130 psi, and delivers an inner holding capacity of 221 pounds. The clamp features a solid bar design with a 90-degree bar opening, a cylinder bore of 1.1 inches, and a closed height of 0.94 inches, making it well suited for low-profile fixture plates where clearance is limited. Licensed trades and industrial maintenance technicians install these clamps in production and assembly environments requiring repeatable, hands-free clamping force.

This clamp is used in vertical-mount fixturing setups on machine tools, welding tables, assembly jigs, and automated production lines. Its compact form factor and pneumatic actuation make it appropriate for applications where manual toggle clamping is impractical or where cycle time demands hands-free operation. The M5 air port accommodates standard push-to-connect fittings common in light pneumatic circuits. Sensor compatibility with round and T-slot sensors allows integration with automated presence-detection systems for closed-loop fixture monitoring.

Key Features

• Pneumatic actuation via M5 port with an operating range of 20 to 130 psi
• 221-pound inner holding capacity for secure workholding under production loads
• 90-degree bar opening angle with a solid, closed-end bar style
• 1.1-inch cylinder bore for consistent, repeatable clamping force
• Compatible with round and T-slot sensors for automated detection integration
• Vertical mounting orientation with M4x6 mounting holes for direct fixture-plate installation

Compatibility

Designed as an OEM-style pneumatic hold down toggle clamp for vertical-mount industrial fixturing applications. Compatible with sensor types: Round and T-Slot.

Installation Notes

Installation is typically performed by a qualified fixture builder, automation technician, or industrial maintenance professional. Shut off and bleed all compressed air supply lines before installing or servicing the clamp. Use appropriately sized push-to-connect or threaded fittings rated for the operating pressure range at the M5 port, and verify that the supply pressure remains within the 20 to 130 psi operating range. Confirm mounting fasteners are secured through the M4x6 mounting holes before returning the fixture to service.
