Pro-Grip Straight Edge Clamps & Accessories

Pro-Grip Straight Edge Clamps for Guiding Routers & Marking Sheet Goods

A straight edge clamp is one of the most versatile shop fixtures you can own. The Pro-Grip system goes further by accepting a range of modular accessories that convert a single clamp into a router guide, a featherboard, a fence, or a hold-down system. This makes it especially useful for working with sheet goods like plywood and MDF, where a full-length guided cut is otherwise difficult to achieve accurately.

The foundation of the system is the Infinity Tools 2" Wide Pro-Grip Straight Edge Clamp, which grips the workpiece along its full length and provides a reference edge for cutting or routing. The Universal Fence Attachment offsets the router base from the clamp edge to dial in precise cut depth and position. For wider panels, the Wide Jaw Attachment extends clamping capacity to thicker stock.

The Pro-Grip Feather Board Kit and Hold Down Kit add workpiece control for router table and table saw use, while the Stop Block Kit enables repeatable positioning for production work. For the complete setup, the 10-Piece Pro-Grip Master Workholding Package bundles the most-used accessories at a better value than buying separately.

Pairing the Pro-Grip System with Other Layout Tools

For marking and layout before clamping, the rulers and squares collection has precision squares and straight edges that pair directly with the Pro-Grip workflow. Browse all measuring and layout tools or return to shop essentials to complete your workshop setup.

Frequently Asked Questions

What is a straight edge clamp used for in woodworking?

A straight edge clamp grips the surface of a workpiece and provides a rigid, straight reference edge along its length. It is primarily used to guide a circular saw or router in a straight line, to mark long layout lines on sheet goods, and to hold panels flat during assembly. The Pro-Grip system extends this with modular accessories for router guiding, featherboarding, and stop-block work.

Can the Pro-Grip straight edge clamp guide a router?

Yes. The Pro-Grip Universal Fence Attachment mounts to the clamp and acts as a router base offset guide, allowing you to rout dadoes, grooves, and rabbets parallel to the clamped edge with consistent positioning.

What thickness of material can the Pro-Grip clamp hold?

The standard Pro-Grip clamp handles most sheet goods and solid wood panels up to typical cabinet-panel thickness. The Wide Jaw Attachment increases clamping capacity for thicker stock. Check the individual product listing for precise jaw opening specifications.

How does the Pro-Grip featherboard attachment work?

The Pro-Grip Feather Board Kit mounts directly onto the clamp body and applies consistent lateral pressure to keep a workpiece tight against a fence on a router table or table saw. This improves cut quality and reduces the risk of kickback on narrow stock.

Can I connect two Pro-Grip straight edge clamps back to back for longer panels?

Yes. The Pro-Grip Back-to-Back Adaptor Kit joins two clamps end to end, extending the effective guiding length to accommodate full-length sheet goods cuts beyond what a single clamp can span.

Is the Pro-Grip system compatible with all router bases?

The Universal Fence Attachment is designed to work with common router base sizes. Fixed-base and plunge routers with standard base dimensions generally fit. Verify the base diameter of your specific router against the accessory specifications before purchasing.

What is the best way to get repeatable crosscuts on sheet goods using the Pro-Grip system?

The Pro-Grip Stop Block Kit mounts to the clamp and acts as a fixed reference point so you can set a cut position once and repeat it across multiple panels without re-measuring each time.

Does Infinity Tools offer a quality guarantee on the Pro-Grip products?

Yes. Infinity Tools stands behind the products it sells. Full details are available at the quality guarantee page.

How does the Pro-Grip system compare to a MFT-style workbench for routing?

A straight edge clamp system like the Pro-Grip is portable and can be used on any flat surface, making it more flexible for shops without a dedicated MFT table. For batch work or operations requiring multiple simultaneous clamping points, a dedicated workbench with integrated clamping may be more efficient.

What other clamping accessories does Infinity Tools carry?

In addition to the Pro-Grip system, Infinity Tools carries specialty and angle clamps for frames and odd assemblies, as well as quick-grip and trigger clamps for general glue-ups and hold-down tasks.
