An infinite door check mechanism for enabling a door to be moved from a closed position in a door frame to any one of a plurality of different open positions including a clevis adapted to be mounted to the frame, an elongate strip member mounted to the clevis and directed outward from the frame, a door check housing adapted to be mounted on the door, the strip member extending at least partially through the housing, and a support member arranged in the housing. A movable locking member is arranged in the housing such that the strip member is interposed between the locking member and the support member. A biasing member such as a spring is positioned in the housing for selectively pressing the locking member against the strip member to force the strip member against the support member and thereby retain the strip member in a fixed position and releasing pressure of the locking member against the strip member and thereby enable movement of the strip member. Structure is also provided to exert a drag force onto the strip member to enable the locking member to rotate without slipping.
