Corner Post Insulators   

Used on the outside of wooden corner posts in permanent fence installations for 20 & 40mm tape. More than one insulator may be required for each post. Use 65 -75mm woodscrews or nails to fix two per insulator (not provided)

Recommendations
For all types of wire, including high tensile galvanised wire, the H.D. for 2.5mm wire insulator listed under 'nail on insulators' can also be used as a corner post insulator.
