Specialty & Angle Clamps for Frames, Corners & Odd Assemblies

Standard bar clamps can't handle every assembly situation. Specialty clamps fill the gaps: corner clamps hold 90-degree joints during glue-up, frame clamps apply even pressure to all four corners of a picture frame or cabinet face frame simultaneously, band clamps wrap irregular shapes, and vacuum clamping systems hold workpieces without any mechanical contact on the clamping surface. This collection of 23 products covers all of these use cases.

For right-angle assemblies, the Infinity Tools Corner Clamps 4-Pack provides four matched clamps that hold all corners of a box or frame square during assembly. The Kreg 90-Degree Corner Clamp with Automax self-adjusts to the workpiece thickness, making it fast to apply without pre-setting jaw width. For cabinet face frame work, the Bessey Cabinet Face Frame Clamp reaches across the stile or rail to hold joints closed during pocket screw driving.

Picture frame and multi-sided assemblies benefit from strap and band clamps. The Bessey Variable Angle Band Clamp wraps around polygons and irregular shapes with adjustable corner blocks, distributing pressure evenly on frames with any number of sides. The Adjustable Four Corner Frame Clamp and Adjustable Frame Clamp with Speed Nut offer mechanical alternatives for rectangular frame clamping.

Vacuum Clamping & Dovetail Hold-Downs

Vacuum clamping holds workpieces without touching the top face, ideal for CNC routing, hand routing, and carving operations. The Infinity Tools Venturi Vacuum System uses shop air to generate vacuum without a dedicated vacuum pump. The Microjig Matchfit Dovetail Clamps slide into routed dovetail slots in jigs and fixtures for low-profile, extremely secure workholding.

Frequently Asked Questions

What type of clamp is best for assembling picture frames?

Band clamps and strap clamps are the most common choice for picture frame assembly because they wrap around all four corners simultaneously and apply even inward pressure. The Bessey Variable Angle Band Clamp handles frames with any number of sides and adjustable corner profiles, making it versatile for both rectangular and polygon frames.

How do I clamp a 90-degree corner joint accurately during glue-up?

Corner clamps hold two parts at exactly 90 degrees while the glue sets. The Infinity Tools Corner Clamps 4-Pack allows you to clamp all four corners of a box simultaneously. Checking with a reliable square from the rulers and squares collection confirms the assembly stays true before the glue cures.

What is a Venturi vacuum system and how does it work for woodworking?

A Venturi vacuum system uses compressed air passing through a venturi nozzle to create a vacuum without a motor-driven pump. The Infinity Tools Venturi Vacuum System connects to a standard shop compressor and generates vacuum at a vacuum cup or pod, holding workpieces flat against a spoilboard or fixture during routing, carving, or sanding.

What are Microjig Matchfit Dovetail Clamps and how are they used?

The Microjig Matchfit Dovetail Clamps slide into a dovetail-shaped groove routed into a jig or fixture. Tightening the clamp expands a wedge inside the groove, locking the clamp in place and pulling the workpiece tight against the jig surface. They provide exceptionally secure, low-profile holding with no overhang above the workpiece.

Can I use specialty angle clamps for cabinet carcass assembly?

Yes. The Bessey WS-3 Angle Clamp and the Infinity Tools Corner Clamps both work well for squaring up cabinet carcasses during glue-up and fastening. For face frames specifically, the Bessey Cabinet Face Frame Clamp is designed for that application.

What are pinch dogs used for in woodworking?

Pinch dogs are small metal staples with tapered legs that are driven across a glue joint to pull the two pieces together and keep them aligned while the glue sets. The Infinity Tools 2" Pinch Dogs 12-Piece Pack is useful for wide panel glue-ups where bar clamps apply all the closing force but don't prevent one board from sliding up relative to another.

How do I clamp an octagonal or irregular frame?

The Bessey Variable Angle Band Clamp includes adjustable corner blocks that can be set to any angle, making it suitable for polygonal frames with six, eight, or more sides. The band distributes tension evenly across all joints simultaneously.

What fence clamps work with router tables and table saw fences?

The Adjustable Fence Clamps in this collection grip fence bodies in the 1/2" to 5-3/4" range and allow accessories or stops to be attached along the fence without drilling. They are useful for securing stop blocks, featherboards, and hold-down devices.

Does Infinity Tools offer price matching on specialty clamps?

Yes. Price matching is available on most products. Submit a request with the competing price at the price matching page.

What other clamping products does Infinity Tools carry?

Beyond specialty and angle clamps, Infinity Tools carries quick-grip and trigger clamps for general assembly, spring clamps for light-duty holding, and the Pro-Grip straight edge clamp system for guiding routers on sheet goods.
