Abstract: A rail flange securement clamp for adjustably mounting a switch point roller assist apparatus on a railroad rail includes a base plate and a top plate, the top plate generally upwardly spaced from the base plate and an adjustable connection device extending between and connecting the base plate and top plate for increasing and decreasing the distance between the base plate and top plate. A rail flange engagement plate having a base section and a rail flange engagement section is adjustably mounted on the securement clamp above the top plate such that the base section is mounted above the top plate and the rail flange engagement section extends outwardly from the top plate for engagement of a flange of a railroad rail thus securing a switch point roller assist apparatus on the railroad rail.
