3MScotchlok Electrical Idc 558-Pouch, Run and Tap, Flame Retardant,Red, 22-16 Awg, 100/Pouch

Buy the genuine 3M Scotchlok product, not an imitation. You will not regret it.

I was using these for landscape lighting on a fence, and were not being used in ground. I ran the 12 AWG wire in a cross beam between posts of a shadow box fence with terminations inside the post. These connectors were small enough to fit in a 1 1/2" hole drilled in the face of the post. if they had had some weather proofing i would have given a five. Since it was above ground and in limited space, this was the best product out there

these are a high quality version of the often cheap version normally encountered. If you have the need for a better wire tap, these are the ones... holding up after a month in my hot engine compartment. for extra protection, a short piece of heat shrink on the connector itself ensures a lifetime closure, but is NOT a waterproofing solution.

These were neither Scottish nor were they locks however they performed very well taping into a bus wire. Even though the color is displeasing they function great!

I just used a number of these to connect electric ceiling heat panels. The old connectors worked fine for over 35 years on the old heat panels and these look to be just as good.
