This Quantum 400 Turnaround Bolt connects the drive chain together. The chain drive arm mounts onto it. Over time, your Quantum 400 turnaround bolt can become worn and possibly break. Installing the Quantum 400 turnaround bolt is a fairly simple process.
The Quantum 400 Travel Chain Turnaround Bolt can be a 3/8 Size or a smaller 1/8 Size on OLD LSI tables..
The 1/8 size goes directly through the chain, and the larger 3/8 size has a metal bracket it installs into.
