Star Point Grounding
I used 3 of these to rewire a 72 Nova and used a star point grounding technique, with 8awg wire connecting the battery to each ground block, avoiding all the grief of bad grounds. Plenty of room, good quality, reasonable price, easy top access with a cap that stays on. I'm not excited about using these for concealed power distribution on the positive side because of potential exposure or shorts without creating some sort of wrap around them, but on the ground side these are great. I decided to buy 4 more of these to rewire a friends classic car ground system next. Plain ring terminals with separate heat shrink worked best to fit the most grounds on all terminals and stack if necessary.

Great flexible cover.
The flexible cover on the negative ground block, from the Online LED Store, won’t break if something hits it. As you can see I added some male quick connect terminals. So all I need to do is connect a ground wire, mount it to the fire wall. And it’s ready to connect off road lights, and put the cover on to protect thing’s from fire and electrical shock. This heavy duty ground block will keep your electrical wiring neat,,,no more spaghetti wiring. I highly recommend this product.

Worked Great to Wire Turn Signals and Horn on My UTV
Used it to wire in turn signals and horn on my Tracker 800 SX UTV to make it street legal. Good quality of manufacture. Terminal bar and screws not flimsy. Allowed me to avoid running multiple supply wires from battery and attaching multiple ground wires to frame. Made for a nice, neat, secure wiring job under the hood of my vehicle.

Units work well for my application. Main posts could be larger on diameter, say 5/16".
