Overview
Comfylichi machines these corner clamps from anodized aluminum to hold two boards at a right angle while glue sets or screws go in. L-shaped rods and adjustable fixing blocks tighten each board against the square.
Hands free squaring of boxes and cabinets is the reason to buy, letting one person assemble corners alone. The listed accuracy range is broad, so precision joinery still needs a check with a trusted square.
Who it's for
Hobby woodworkers and DIY builders making drawers, birdhouses and frames get four corners held square at once. Furniture makers needing exact precision or clamping thick slabs should look further.
Pros and cons
- Four clamps for a full box
- Aluminum resists deformation
- Scales on both sides
- Adjustable for board thickness
- Accuracy range up to half a degree
- Board thickness limit
- Nut material described two ways
- Weight not listed
Performance notes
Each clamp references both boards against machined faces, so squareness depends on the CNC tolerance and on even tightening. Overtightening one side can pull a board slightly off the face.
