How It Compares
Compared With Corner braces
A mending plate splices along a straight line; a corner brace works across a right angle. Choose by the geometry of the joint, not by strength alone.
Use Guide
- Centre the plate on the joint so the same number of fixings lands in each member.
- On a structural splice use bolts through the plate rather than screws.
