Infinity Tools Corner Clamps, 4-Pack

The Infinity Tools Corner Clamps, 4-Pack are used to hold two boards at a precise 90-degree “inside corner” angle while glue cures or while you fasten them. They’re ideal for making cabinets, boxes, drawers, shelves, or any woodworking or carpentry project requiring right-angle joints. Their adjustable triangular inner jaw lets you accommodate different board thicknesses, simplifying assembly in tight spaces.

These corner clamps can open wide enough to clamp boards up to ¾″ x ¾″ thick. If your boards are thinner (for example, ½″), the triangular inner jaw can slide to allow proper clamping. The body of the clamps is made from a nylon-filled plastic, which offers durability, resists glue squeeze-out, and holds up under repeated use without being bulky.

To use these clamps effectively:

1. Apply glue to the mating surfaces of your boards.
2. Place one clamp at the inside corner where the two boards meet.
3. Adjust the triangular jaw so both boards are fully seated and flush.
4. Tighten the clamp so the boards are held rigidly at a right angle.
5. Allow glue to set or complete fastening (nails, screws, etc.) while the clamp holds the joint steady.
   
   Because the clamp is low-profile, it’s easier to align and work around in tight spaces compared to bulkier clamps.

The 4-pack offers good value since it provides multiple clamps at a lower cost per clamp, allowing users to clamp more than one corner at once or have backups handy. Typical applications include furniture making, cabinetry, small craft projects, picture frames, and general carpentry where right angles are essential. Because the clamps are compact and plastic, they’re lightweight and easy to store.
