- Additional information
Spacer plates are often used when assembling complex structures using both corner blocks and Generico Flex Joints (grapples). Corner blocks typically are 3/8″ larger that 12 x 12 truss on most or all sides. When assembling a box configuration with corner blocks, then adding in additional spans, the corner blocks create a 3/8″ space on each end where the spans attach to the sides of the box. Adding a spacer plate to each end fills the gaps and allows for safe installation of the additional spans.
