Achieve a true 90° corner—or any angle from 10° to 180°—without a second pair of hands, because this clamp secures both the pieces and the angle so the joint you glue, screw, or weld is the one you planned.
Constructed with a die-cast aluminum body and steel screws, it resists flexing and cracking under real pressure, unlike cheaper plastic corner jigs. The V-jaw pins the workpieces at the exact angle you select, keeping the corner square while you work through drilling, gluing, screws, or welds.
Once the jaws bite, your piece stays put, freeing your other hand for fastening. The bite comes from a trapezoidal A3 steel screw that rides each arm—the same flat-threaded screw used on bench vises—so it grips hard and resists backing off under load. Turning the wheel right lowers the jaw to bite; turning left releases the grip. This lets you maneuver with two fingers, not a tug-of-war.
Angle options and overall design: pick the fixed 90° style for square frames, boxes, and right-angle corners, or rotate the swivel head to set any angle between 10° and 180°, then secure it with the included hex wrench. It clamps wood, steel tube, and aluminum profile while you work.
Key measurements: the fixed 90° version runs roughly 277 mm wide by 123 mm, while the 10°–180° swivel version stands about 140 mm tall by 120 mm. The arms are die-cast aluminum with trapezoidal A3 steel screws (M8/M10). Jaw opening reaches up to 50 mm, jaw depth is 16 mm, and screw reach extends to 40 mm. It handles wood, steel tube, square tubing, and aluminum profile frames.
Three simple steps to square corners: first, select your angle—either fixed 90° or the 10°–180° swivel—and lock it with the included hex wrench. Next, place both pieces into the V-jaws so their meet point aligns. Finally, tighten the hand wheels until the jaws bite, then proceed to fasten, glue, or weld with both hands free.
Why this clamp stands apart: it locks the angle itself, not just the surface, and you have two form choices—90° fixed or 10°–180° adjustable—while maintaining capability across wood, steel, and aluminum profiles. Die-cast aluminum arms and durable A3 steel screws resist flex and backing off under load, unlike plastic jigs that warp. You get square corners with minimal drift during glue-up, screw driving, or welding.
If it doesn’t hold your joint dead-on, you can return it for a full refund—no risk, no close-enough results.
