The Pacific Shoring Products Single-Piece Extensions are used to extend the overall range of a 2-inch hydraulic cylinder. This extension is designed to provide quick and efficient installation on both solid and hollow rod applications. What sets this extension apart from traditional full-length oversleeve extensions is that you can use them on any of the six standard cylinder sizes. The single welded extension unit can be conveniently added or exchanged onto hydraulic cylinders in the field. Single-Piece Extensions are available in lengths from 6 Inches to 56 Inches and can be ordered with custom intermediate spacing if necessary.
