The Modulift Trunnion Spreader is modular in length. Every Trunnion spreader consists of two End Units and
intermediate struts that can be bolted into the assembly to achieve diff erent spans. The Trunnion End Unit is
also compatible with existing Modulift struts. The TRUN MOD 250/400 has an assembled span ranging from
6 ft to 68 ft in 1 ft increments.
