ST722 Series The Studded Power Feed Thru were designed for applications where power feed thru is necessary using standard double hole lugs with.625 spacing. These terminal blocks are available in three mounting options (end mount, back mount, and slide-in mount). They are also offered in various line lengths and with various hardware options (See Hardware Descriptions Below). These terminal blocks lower cost by eliminating multiple components and assembly time. The terminal blocks are manufactured from top quality insulator and conductor materials. They are designed with a robust one-piece insulator base using a one-piece conductor permanently assembled together. Covers are molded using a one-piece design and are available as an option for all three series of these blocks.
