The tool is made of stainless steel, which is durable, corrosion-resistant and not easy to bend The handle of the tool is designed to prevent slipping, which increases the friction force and prevents slipping when used. One end of the tool is designed with a half cut, which is convenient for installation and decoupling. Using it for installation can ensure the spring tension is tight enough to prevent anyone from removing the spring without the rod tool. Install:Insert the rod into the spring ferrule. Fix the open end of the rod on the anchor, slide on the grommet and let it down, hook the spring on the anchor. Remove: Insert the rod on the anchor, rotate to half turn.
