Terminal Blocks Come In Highly-Identifiable Colors

BlockMaster Electronics introduces an expanded offering to its popular Jelly Beans line of colorful terminal blocks.  The latest modular JB6 Series features thermoplastic terminal blocks in multiple colors for ease in identifying terminations and preventing costly field wiring mistakes.


In addition to color coding, the company offers screen printing to mark alphanumeric characters on its JB6 Series terminal blocks to further simplify field wiring.  The JB6 Series provides a simple and effective means of differentiating field wiring connections by color, custom legends or both.
