8 Pack Battery Terminal Lug Boots Covers, Red & Black Insulating Caps for Ring Terminals/Cable Lugs, Fit Terminal Post up to 20mm (0.79"), Fit Cable up to 12mm (0.47"), for Car Truck RV Solar

Very durable she good quality

Fit was very tight which is good they will not vibrate off.

They worked for what I needed, but were a little light duty. I will see how long they hold up.

As advertised

I had two separate wires with separate ring terminals. I was not sure the ring would fit through the small opening for the wires; and I was not going to remove the terminals. I was prepared to cut and zip-tie the boots if it came to that. I was very pleased when boots stretched enough to get both rings through the wire opening. These are tough and flexible. The wire opening snapped back to hug the wires as they should. They worked perfectly for my application. Time will tell if they harden with age. For now they are great.

I ordered these to cover positive posts on a driving light solenoid installation. Very pliable, seemed sturdy so far, and was able to use them on 8 GA power wires with no problems.

I made an obsolete battery harness for a Snapper mower. Perfect for the positive connection to the battery.

When order didn't know if it would slip over my # 2 wire and others I had run to post . But it was flexible enough to slip and stretch over , worked great. Very pleased.
