Gibraltar 33825G Manual Edge Clamp Steel Black Oxide

Product Description

The GIBRALTAR 33825G is a manual edge clamp with a low grip nose profile, designed for secure workholding applications on machining fixtures, jigs, and fabrication setups. Built from steel with a black oxide finish, this clamp provides corrosion resistance and a clean appearance suited to shop environments. It measures 5.3125 inches in overall length and 1.5 inches in overall width, with a height of 0.875 inches. A 0.5-inch socket cap screw slot accommodates standard cap screws, and the clamp delivers 2 inches of travel for flexible positioning across a range of workpiece thicknesses. Machinists, toolmakers, and fixture builders are the primary installers of this type of clamp.

The 33825G is suited for use in manual workholding setups where a low-profile edge clamp is required. The low grip nose allows clamping close to workpiece edges without interfering with toolpaths or adjacent fixtures. It is commonly used in machine shops, fabrication facilities, and toolroom environments on milling machine tables, modular fixturing plates, and custom jigs. The 0.5-inch socket cap screw slot allows integration with standard T-slot or tapped fixture plates using commonly available fasteners.

Key Features

• Low grip nose profile for edge clamping close to workpiece boundaries
• Steel construction with black oxide finish for durability and mild corrosion resistance
• 2 inches of travel for versatile workpiece thickness accommodation
• 0.5-inch socket cap screw slot for compatibility with standard fixturing fasteners
• Compact form factor at 5.3125 inches overall length and 1.5 inches overall width
• 0.875-inch height keeps a low profile on fixture plates

Compatibility

Designed as an OEM-style replacement or direct-use manual edge clamp for standard workholding fixture systems accepting 0.5-inch socket cap screw fasteners.

Installation Notes

Installation is typically performed by machinists or toolmakers using a standard hex key or Allen wrench sized for the socket cap screw. Secure the clamp to the fixture plate before applying clamping force to the workpiece. Ensure the fixture plate and mounting surface are clean and free of chips or debris before torquing the fastener. Always verify that the clamp is fully engaged and the workpiece is stable before beginning any machining operation.
