JC Whitney sells flat black shrink tubing, and it is sold in 10' lengths for around $8.. it shrinks up good

I always use the crimp connectors but prefer the non insulated ones and heat shrink. I only use a certain model of Thomas and Betts crimper, not those cheap ones with the striper built in. It is as good as solder, probably better in many situations. Also I pay attention to which side of the connector the crimper is engaging. It has like a tang and a valley and you want the seam of the connector in the valley most of the time.
It looks like the person working on the column didn't know you could disengage the wires from the connector to feed them through the column..
