Dimensions & Drawings
Pole Cap covers the top of a wooden power pole to keep out water and moisture, extending pole life.
Supplied in an expanded form. Heated above 125°C with a propane or butane torch (soft blue flame, yellow tip; avoid a pencil-thin flame or scorching), it shrinks down over the pole top, closed end first, with adhesive visible at the finished edge. Let it cool before applying mechanical strain.

FAQs
Frequently Asked Questions
What is the Pole Cap used for?
It is used for:
- Wooden power pole top protection
- Utility pole maintenance and life extension
How do I choose the right size?
Measure the outside diameter of the pole and choose the code whose "Pole Range" covers it. For example, GPC 901 fits a pole of 140–280 mm. Where two ranges overlap, either code fits.
How is it installed?
Clean and degrease the surface, position the part, then shrink it with a gas torch or a hot-air gun: keep the heat moving round it with a smooth, brushing motion so it recovers evenly without scorching. Start at one end and work steadily along to the other.
Which standards and test methods are quoted for it?
These:
- ASTM D638
- ASTM D570
- ASTM D2671
- ESI 09-11
- ASTM D149
- ASTM D257
- ASTM D150
