{{Short description|Military equipment}} {{One source|date=December 2025}} thumb|An old capsquare (both top and bottom pieces) In artillery, '''capsquares''', or '''capsquires''', are strong plates of iron which come over the trunnions of a cannon, keeping it in its carriage. They are fastened by hinges to the paizeplate, so that it could be lifted up and down. They form a part of an arch in the middle, to receive a third part of the thickness of the trunnions; for two thirds of them are let into the carriage, and the other end is fastened by two iron wedges, which are called the forelocks, and keys.
