Clevises

Clevises are components of tie rod assemblies that are manufactured by BBI and are largely used alongside turnbuckles. The clevis tends to support a threaded rod at both ends in a standard cross bracing assembly. One end of the clevis is gripped well onto a steel plate and is secured with a pin.
