Relitec R 90 Degree Corner Clamp Clamping Squares Woodworking Tools Positioning Squares Right Angle Clamp Wood Clamps for Gluing Cabinets Picture Frames or Drawers Set of 8（3" 4"）

I purchased these 90° clamping squares after watching Mark on Start Making (Woodworking). He rated the product highly due to it being accurate (and square). The items are well made and perfect for the job. Thank you!

Does as intended

For simple squaring up picture frames etc these work well - you're unlikely to get pin-point accuracy, for that you'll need an engineer's square, but for bog-basic squaring-up, these will do.

Just great bit of kit

I actually use them quite a lot but there are better versions out there but they are square.

great for holding wood in position when gluing do need clamps to hold in position
