RS PRO Steel Extension Spring, 49 x 7 mm


You can use this steel extension spring from RS PRO to attach two objects that require regular limited movement away from each other. It has a tight coil that absorbs and stores pulling force, bringing the items back together after they have been pulled apart.

The spring is made from carbon-steel piano wire, so it has high tensile strength. This makes it suitable for heavy-duty applications such as linking large, bulky objects. It's also easy to install, as it has two closed loops at either end for a quick and secure connection.

As with all our trusted RS PRO range products, this spring has been thoroughly tested by engineers to ensure our high standards of consistency and quality. Springs like this are often used to attach retractable garage doors or on trampolines.
