Frequently Asked Questions

Q: What materials can these 90-degree corner clamps hold?

A: These right angle corner clamps are designed for wood, MDF, plywood, and similar panel materials. The adjustable opening accommodates thicknesses from 5mm to 22mm (0.19 in to 0.86 in), making them suitable for a wide range of woodworking and DIY projects including cabinetry, picture frames, and shelving.

Q: Can I use all four corner clamps at the same time?

A: Yes! That's one of the biggest advantages of this 4-piece set. You can clamp all four corners of a frame or box simultaneously, ensuring every joint stays at a true 90-degree angle while adhesive sets or fasteners are driven in — saving you time and improving accuracy on complex projects.

Q: Do the rubber heads protect my workpieces from damage?

A: Absolutely. The non-slip rubber clamping heads are designed to grip surfaces firmly without scratching or marring them. This is especially important for finished wood surfaces, veneered panels, or delicate picture frame materials where surface protection is critical.

Q: Are these clamps suitable for welding or metalwork?

A: These clamps are made from ABS plastic and rubber, making them best suited for woodworking, carpentry, and light DIY tasks. While they can be used as alignment guides for some light metalwork, they are not designed for heavy-duty welding applications that require metal-body clamps.
