De-sta-co 807-U-RC Pneumatic Hold Down Toggle Clamp

Product Description

The DE-STA-CO 807-U-RC is a pneumatic hold down toggle clamp designed to secure workpieces during machining, assembly, and fixturing operations. It delivers an inner holding capacity of 375 pounds (1670 N) with a maximum mechanical advantage of up to 6.4:1, making it well suited for high-cycle production environments. The clamp features a solid bar style with a 103-degree bar opening and 1.38 inches of clearance under the bar. A 1/8 NPT port accepts standard pneumatic supply lines, and a flanged washer is included. Installation is horizontal, and the unit weighs 1.3 pounds. Typical installers include fixture builders, manufacturing engineers, and machine shop technicians.

The 807-U-RC is used in horizontal-mount clamping applications on jigs, fixtures, and workholding setups in both production and job-shop environments. The 103-degree bar opening allows adequate clearance for loading and unloading parts quickly. With an operating temperature range of 14 degrees F to 194 degrees F, it performs reliably across a wide range of shop and industrial conditions. Sensor compatibility with round and T-slot mounting configurations adds flexibility for automated or monitored fixturing lines where cycle confirmation is required.

Compatibility

Compatible with round and T-slot sensor configurations. Accepts standard 1/8 NPT pneumatic fittings. Designed for horizontal-mount fixture and workholding applications requiring pneumatic hold down clamping.

Installation Notes

Installation is performed by fixture builders or mechanical technicians following the workholding system layout. Disconnect and exhaust all pneumatic pressure from the supply line before mounting or servicing this clamp. Use appropriately sized fasteners through the 0.28-inch mounting holes, referencing the mount hole spacing of 0.75 inches between centers lengthwise and 1.25 inches widthwise. Verify the air supply does not exceed the 10 bar maximum operating pressure before placing the system into service.
