Show Solutions 20.5" x 20.5" Sleeve block

The sleeve block for 20.5" tower truss. It rides on the outside of a TT-2020 tower and carries the header truss, so a roof or lighting grid can be assembled at deck level and then driven up the tower to trim by the hoist. Because it wraps the tower rather than pinning to one face, load stays centered on the tower as the grid climbs. Sized for the 20.5" x 20.5" tower profile and used with the matching 20.5" head block at the top of the stack.
