De-sta-co 81L12-14100 Pneumatic Hold Down Toggle Clamp

Product Description

The DE-STA-CO 81L12-14100 is a pneumatic hold down toggle clamp designed for vertical mounting in fixture, jig, and workholding applications. It uses compressed air supplied through an M5 port to drive a solid-bar clamping arm through a 90-degree opening arc, generating a holding capacity of 177 pounds at the inner clamp point. Operating air pressure ranges from 20 to 130 psi, giving this clamp a wide working envelope across standard shop air systems. The closed-end bar and pneumatic cylinder bore of 1.1 inches provide consistent, repeatable clamping force cycle after cycle. Licensed trades and fixture builders working in manufacturing, assembly, and precision machining environments rely on this style of clamp for automated or semi-automated hold down operations.

This clamp is suited for production line fixtures, welding positioners, CNC workholding setups, and assembly jigs where pneumatic actuation replaces manual toggle effort. The vertical mounting orientation and M5 port make integration into existing pneumatic circuits straightforward. Sensor compatibility with round and T-slot sensor types allows for cycle confirmation and automation feedback. The compact closed height of 0.94 inches keeps the profile low when not in use, reducing interference with workpiece loading and unloading.

Key Features

• 177-pound inner holding capacity with pneumatic actuation via M5 port
• 90-degree bar opening arc with solid, closed-end bar style
• Operating pressure range of 20 to 130 psi compatible with standard shop air
• 1.1-inch cylinder bore diameter for consistent clamping force
• Vertical mounting orientation with M4x6 mounting holes spaced 0.59 inches (length) and 0.35 inches (width) apart
• Compatible with round and T-slot sensor types for automation feedback

Compatibility

Designed as a pneumatic hold down toggle clamp for use in industrial fixture, jig, and workholding applications requiring vertical-mount pneumatic actuation with M5 port pneumatic circuits.

Installation Notes

Installation is typically performed by a millwright, fixture builder, or maintenance technician familiar with pneumatic circuit assembly. Isolate and bleed down the pneumatic supply line to zero pressure before connecting or disconnecting the M5 port fitting. Mount using M4x6 hardware through the designated mounting holes and confirm the clamp arm swings freely through its full 90-degree arc before applying air pressure. Verify that air supply pressure stays within the 20 to 130 psi operating range to avoid under-clamping or component damage.
