Leading Electrical Terminal Block Manufacturer

We manufacture standard and custom terminal blocks for a wide variety of applications and for nearly any industry. Our connectors are designed to support a wide range of wire-to-board and wire-to-wire configurations and are available in many styles and sizes. All of our wire terminal blocks meet industry standards and are ISO, CSA certified ,We use only the highest quality copper alloy in the terminal bodies.


There are a wide variety of wiring terminal block types and sizes to fit every unique industry’s electrical connectivity requirements. We manufacture barrier-style terminal blocks, DIN rail blocks and PCB blocks. Our barrier-style blocks are available in single row, dual row and high voltage configuration. They are also built with thermoplastics to resist breaking in extremely high temperatures. DIN rail blocks can be manufactured with either screw or screwless connections to make installation easier. We also manufacture fuse and ground DIN rail blocks.  The PC board blocks are available with single or multi-level rows, and are available with multiple profile options.

Most terminal blocks are available with three different wire entry angles; 45, 90, or 180 degrees. Depending on your application, our engineers can design a working terminal block prototype for your approval. We can produce a single unit for a specific project, or multiple stackable units which can be mounted right next to each other to save space.
