The Insta-Trim 12727-A Hydraulic Cylinder with Hose is a single hydraulic actuator intended for Insta-Trim Boat Leveler trim-tab systems. Its cylinder body and swivel mounting brackets are constructed from high-impact, glass-filled nylon. Swivel-style brackets at both ends allow the cylinder to be installed at a range of mounting angles, including up to 90 degrees. This design accommodates transoms that are not perpendicular to the bottom of the boat without requiring blocking or shimming.
