Nice solution
We moved nine months ago across town, and after I finished out my shop, I needed a bus bar for my HAM radio set up. So I drove a ground rod deep into the ground, just outside my shop and hooked it up to this bus bar, then tied the two bus bars together. These are very nicely made, and arrived quickly. I like that there’s two of them which makes them fit into a small smaller space. Nice solution.

Part of our system
We try to buy from the Ma and Pa places on here. Being disabled . We need to be price conscious. At "The Mother In Laws Place" It is an off-grid cabin, we run DC on a lot of things . We see no need to use the inverter 24/7. just so you can turn on a light when you come home . We use LED bulbs in ceiling mount fixtures that are marked 12-volt DC only. These are controlled by controller with a FOB remote. The controller is board mounted on our PV control center . We use a few of the controllers for different rooms to control each ceiling light . We also run the kitchen stove exhaust fan with DC . The fresh air intake system for combustion is DC . These are fused in our DC only fuse center . This fuse center is controlled by a service disconnect at the DC master box . We also run two AC fuse boxes on our PV board . One protects various AC 110 volt circuits in the cabin , garage and sauna . The other protects 220 volt circuits from the aux gen set and to the split ac/heat pump and the aux battery charger for when the PV and hopefully soon to be wind generated power are not enough to keep up. We run 8 - 6volt Rolls batteries tied by Buss bars . They are temperature and voltage monitored on the PV board and by the inverter unit. The power is inverted by a Renogy 3000 . It also has a multi stage charger built it with flow through capability . These are almost all protected by Breakers purchased here . We have a remote shallow well system that we use a soft start unit on . It lessens the instant draw on the system . It is all about power management. This is a semi detailed , general description of some of the off grid power systems we use .

Perfect for grounding amateur radio equipment!
I recently passed my technician, general and extra amateur radio exams. Then I purchased some nice radio gear. I read that nearly all radio gear must be grounded. After looking at all sorts of options, this RLECS 2pcs Terminal Bus Bar Terminal Block Brass Wire Screw Terminal Grounding Strip Bus Bar Block popped up during a Google search. I purchased it, installed it, mounted the ground wires and am super happy with how easy it was to install and use! A+++++++++++

RLECS 2pcs Terminal Bus Bar Terminal Block
I used this to ground my Cellular Exterior Antenna. I have a Waveform panel Cellular antenna, which has 4 internal antennas. I was able to ground each lightning surger protector to the RLECs Terminal Bus Bar and then to a ground stake that is in the ground.

Okay but not great.
One end was attached at an angle. Since no one can see it I used it anyway.

Negative block
Better focal point for grounding multiple negative wires

Junk
The screw heads crumble on a #12 solid grounding conductor, not over torqued. Will replace with better.
