No Walking Self-Leveling Self-Aligning Roller Head - we make roller heads for the most popular jack stand brands: Sumner, Mathey B&B and Javelin. (Please indicate your jack stand type in the notes). This roller head dropers right on top of a standard V-Head jack stand. It converts it to a silky-smooth roller head and includes 3 holes for different size pipe. Far less likely to walk allowing the pipe welder to be more efficient and safer in the field.
