$6.29 to $6.39
Screw-in type "donut" insulator for wire and tape up to 1/2" wide. Large lag screw eliminates the need for pre-drilling. May be used as a corner insulator also.
"By far the best"
These are by far the best wood post insulators on the market. Another company makes a 'similar' insulator, but the plastic is not as dense and they break easily. I have been using this insulator for several years and they are tough and strong.
