Terminal blocks are one of those parts nobody thinks about until they’re missing the right one mid-build. A proper kit with jumpers, ground blocks, end covers, and mounting rail included saves a trip back to the supplier and gives you a genuinely UL-listed part instead of an unmarked generic block.
What It Is
This is a 20-position DIN rail terminal block kit built around genuine Dinkle DK2.5N blocks, rated 12 AWG / 20A / 600V, and includes ground blocks (DK2.5N-PE), jumpers (DSS2.5N-10P), end covers, and end brackets — everything needed to assemble a working terminal strip out of the box.
Key Features
- 20 Dinkle DK2.5N terminal blocks, 12 AWG gauge, 20A, 600V rated
- Includes ground terminal blocks and jumper bars
- End covers and end brackets included for a finished, safe assembly
- UL Listed components, not generic unmarked blocks
- Red/black color-coded kit option available for circuit identification
Pros and Cons
Having jumpers, ground blocks, and end hardware bundled in one kit means you’re not guessing at compatible part numbers or placing three separate orders to complete one terminal strip. At 4.7 stars, Dinkle’s terminal blocks have a strong reputation in the panel-building community specifically for being a reliable, genuinely UL-listed alternative to unbranded blocks.
At $28.99 for 20 positions, it’s priced higher per-block than buying loose generic terminals in bulk, but the certification and included hardware are what you’re paying for — not padding.
Who It’s For
Panel builders who want a complete, certified terminal block assembly rather than sourcing blocks, jumpers, and end hardware as separate line items.
Verdict
For panel builds where UL-listed terminal blocks matter, this Dinkle kit is a complete, no-guesswork way to get there.
