A hand brake of the non-spin type for railroad cars including a front casing and rear attachment plate that define a housing space for the brake operating shaft, ratchet wheel, ratchet wheel clutch, brake release mechanism, and drum gear, that is sealed from the elements by a seal applied between the two. The front casing is indented to define a mounting space for a single wind type brake drum, which is keyed to a mounting shaft that is journaled between the casing and a brake drum cover plate that may be secured to the casing in various positions relative thereto depending on the particular hand brake application desired. The drum extends into the housing space where it has fixed to same the drum gear and the drum carries a headed pin that anchors the brake chain to the drum, with the pin head cooperating with a stop block fixed to the casing to form a chain stop.
