Good luck getting the plastic cover on after you use them.

The after market compressor terminal kits are nice. Better to use them on a new compressor than one that had a terminal fried. Usually you use one when the wires get burnt up.

But they are attached via a thread on brass fitting tightened with a flat head bolt. Much better connection

Do any residential compressors have a better method of bringing power to the compressor terminals than the little "flags" that are welded to the round terminals with a fast-on slipped onto the flag?

There is a reason that fast-on connectors are not used in airplanes.

My flag completely burned up. I cut the fast-on to leave just the barrel and tied the barrel onto the compressor post with tie wire. I have 4 tie wire jury rigged loops on one compressor post. I ordered a Term-Lok from ebay.
