Mrorea 90 Degree Aluminum Corner Clamps

Get a perfect 90° corner without fighting your workpiece. The Mrorea 90-Degree Corner Clamping Squares act as a rigid extra set of hands, locking cabinet, box, and frame joints square while you drive screws or glue up. CNC-machined from anodized aluminum, this 4-piece set is built to stay accurate build after build.

Product Features

Flawless Right-Angle Alignment

Getting a clean right angle during a complex glue-up no longer has to be a fight. This set of four 90-degree clamping squares gives you solid, repeatable support for cabinet assembly, box gluing, frame fastening, and furniture building—a workshop staple you’ll reach for on every build.

CNC-Machined Durability

Where plastic or cast clamps can warp and crack under pressure, Mrorea positioning squares are built for the long haul. Machined with 5-axis CNC precision, they hold a tight geometric tolerance of ±0.02°, and the premium anodized finish resists corrosion and rust through years of heavy shop use. Each clamp is rated for 3,000+ wear cycles.

Rapid Tool-Free Calibration

Set up in under two minutes—no tools needed. Seat the square flush against the corner of your workpiece, insert the positioning bolts, and turn the ergonomic knobs clockwise. The clamp draws both pieces together tightly and evenly into an exact 90-degree corner.

Hands-Free Joint Fastening

Clamp all four corners at once and let go. Acting as a rigid second set of hands, these corner clamps lock your joints in place—no slipping, shifting, or racking—so you can focus on driving pocket screws, laying down glue, or checking your cross-square measurements.
