Claim:
1. A door catch, comprising: a ball plunger assembly including a body with a threaded exterior, a tool-engaging plunger base, a spring, and a ball captive within the body and loaded by the spring to partially extend out of the body opposite the tool-engaging plunger base; a catch bar bracket including a first mounting portion and a catch bar base projecting directly away from the first mounting portion; a catch bar including a catch bar bottom surface in which a detent is formed, the catch bar bottom surface being constrained to move along a top surface of the catch bar base with one degree of freedom, allowing incremental adjustment of the catch bar relative to the catch bar base; a ball catch base including a second mounting portion and a base portion projecting directly away from the second mounting portion, the base portion including a base portion top surface and a base portion bottom surface with a threaded aperture therethrough that receives the ball plunger assembly; the catch bar bracket and the ball catch base being mountable on opposing vertical surfaces of a mounting structure and a door by the first mounting portion and the second mounting portion, respectively, so that the ball and the detent frictionally engage vertically to hold the door in an open position, and a force of impinging of the ball against the detent is adjustable by rotating the body within the threaded aperture causing the ball to raise or lower with respect to the base portion top surface; and the catch bar bottom surface and the top surface of the catch bar base include complementary serrated portions that engage to hold the catch bar in one of its incremental adjusted positions relative to the catch bar base.
