The Spann-Box® Type 2 offers a wide range of variants to meet diverse requirements and is the largest chain tensioner in our product range. Choose between a curved profile, semicircular profile, or deflection profile. Its robust steel housing ensures high durability and reliable performance, even under challenging operating conditions.

For chain systems with alternating running directions, we recommend the version with an extended housing and "heavy" tension force. This variant is specifically designed for reversing operation, ensuring constant tension even under dynamic stresses.

The Spann-Box® is mounted easily underneath the chain and seamlessly integrates into existing systems.

Semicircular profile: Ideal for tight installation spaces where maximum space efficiency is required.
