Use this RS PRO spring to allow your gate to close on its own after being left open for an extended period of time. Thanks to its steel construction, it's durable and resistant to corrosion, making it a good choice for use in harsh industrial environments.
It comes with a tensioning rod that can be used to increase or decrease the spring's rigidity or pull on the spring, as well as rivets to keep it in place. The included screws also make it easy to install using a cordless screwdriver. This spring has a free length of 200 mm for excellent elastic tolerance, so you can tighten or loosen it without risk of damage.
