This Inline Chain Tensioner for #25 series roller chain is perfect to adjust the desired tension in a long run of chain on mechanisms such as elevators and arms. This is ideal where there is at least a ~3″ section of chain that never passes over a sprocket in a given mechanism. Pair this with two #25 Master Links and integrate this to your robot for an easy-to-use chain tension solution!

The design of this product was inspired by Misumi’s Chain Turnbuckles. This product has been improved to be compatible with imperial-sized wrenches.
