ABSTRACT:
A door catch includes a back plate having two laterally symmetric sleeves formed on a front face thereof. A slot is provided on the back plate behind each of the sleeves at a predetermined position to communicate with an inner space of the sleeve, and an insert plate is inserted from a back face of the back plate into the sleeve via the slot to confine a steel ball and a spring in the sleeve, such that the springs not only normally push the steel balls forward to partially project from front open ends of the sleeves for tightly clamping a corresponding stop post between the balls, but also tightly push against the insert plates to hold the latter in place. The insert plates are held down in place in the sleeves by a wall when the back plate is mounted on the wall with fastening elements.
