An improved roof or ceiling fitting for a monorail system, particularly useful in low seam coal mines. Rail suspension assemblies are each secured in a single counterbored roof hole and are adjustable vertically and laterally for alignment. A bolt is anchored in a hole and supports a collar-end of a crank-shaped suspension unit within the counterbore. A suspension-pin end offset from the collar axis extends below the roof to support a cleat for attachment to a rail. A roof plate is threaded on the collar and bears against the roof.
