What are "Straight Corner Fixing Brackets" used for?
They can be installed in various ways. You can install them to join corners straight from one surface to the other, or diagonally from one surface to the other. You can also use them in a situation where you want to allow the expansion/contraction or slight movement of a fixture. This would allow say a table top to expand or contract with temperature or humidity changes. This would then keep the table top from cracking.
