Grounding Block/Terminal Block/Buss Bar
This compact, high quality grounding block is CNC machined out of UHMW high density plastic and is manufactured by Superior Panel Technology. It comes complete with a nickel-plated copper buss bar and stainless steel nuts with nylon lock washers, stainless steel flat and locking washes and 6 stainless steel screws (5 are 6/32 screws and one is 8/32 for the incoming ground/power). Each screw can accept up to four ring terminals by placing them back to back (see picture). Overall dimension is 4.25" long by .75 wide.
This terminal block is exactly what I needed for my homebuilt aircraft. I originally purchased one for a grounding block but liked it so well that I purchased a second one for a positive buss bar.
Good bus bar, quality built.
Not one to complain but stay away from this one. 3 screws broke and 1 stripped during assembly. #6 screws not matched to #8 holes in buss bar. Could avoid breaking screws by pressing them in as opposed to drawing them through the block as specified in the directions however, the #6 screws are very weak so I suspect a lot of them get broken when attaching lugs.
