Overview
A garage workbench or a hobby room is where these YICYIO squares help, holding two boards at a true right angle while glue sets. Fixing blocks tighten with L-shaped metal screws, and the squares pair with most bar clamps.
Four squares let you hold every corner of a frame or drawer at once. Plastic flexes under heavy clamp pressure, so they suit small to medium projects.
Who it's for
Picture framers, birdhouse builders and furniture hobbyists get four corners held square. Metal fabricators or anyone needing mitered angles need different clamps.
Pros and cons
- Four corners held at once
- Built-in two-sided scale
- Chamfered edges spare hands
- Fits most bar clamps
- Ninety degrees only
- Plastic flexes under heavy force
- Thickness limit for thick stock
- No metal jaws
Performance notes
The square sets the angle while the fixing blocks press each board against it, so accuracy depends on the boards seating flat. Plastic flexes if overtightened, so snug the screws rather than cranking them. Chamfered inside corners leave room for glue squeeze-out.
