Frequently Asked Questions

Q: What types of boxes are these metal corner protectors compatible with?

A: These metal corner protectors are designed for a wide range of enclosures including tool boxes, flight cases, air boxes, aluminum cases, wooden boxes, luggage, chassis, and postal boxes. If your box has standard square corners, these brackets should fit perfectly.

Q: Which size should I choose — 23×23mm or 28×28mm?

A: The size refers to the bracket's face dimensions. The 23×23mm option is suited for lighter-duty or thinner-walled boxes, while the 28×28mm option works better for thicker walls or larger case corners. Measure your box corner before ordering to ensure the best fit.

Q: Are these corner protectors pre-drilled or do they require drilling?

A: These corner brackets typically feature pre-drilled screw holes for easy mounting. You will need to secure them with appropriate screws (not included) based on your box material and wall thickness.

Q: How many corner protectors come in the pack?

A: Each order includes 4 metal corner protectors — enough to cover all four corners of a single box or case.
