Both stud type and integral box connector versions are offered to allow for user preference of wire terminations. The integeral box connector versions also provide for greater heat dissipation. All modular blocks are supplied in pairs but need to be ordered as two items to suit one fuse. Mounting hardware is supplied with the blocks.
