The 700119 from Sherman + Reilly is a small fitting bit of hardware that is used to hang/suspend blocks from supports. The No.1 Hook w/ Clasp mates with the socket connector at the top of the block frame by simply sliding/snapping the fitting’s ball-eye into the socket of a socket connector. The other end of the fitting then mates with whatever the supporting hardware may be: for example, a hook, a bracket, or over a cross-arm or an insulator using webbing loop of a “Noose.”
