Open Construction Terminal Blocks

Our Bulletin 1492 Open Construction Terminal Blocks (Styles C and F) provide visual verification that the wire is properly positioned in the clamping area. You can use a standard screwdriver for wiring the blocks. Styles C and F blocks mount more securely on Allen-Bradley® rail; some also mount on DIN rail. Several Style C blocks accept snap-on markers for marking long wire identifications.
