18mm x 18mm Square Fence Post Cap | Black Polyethylene
This square fence post protector is shaped for 18mm x 18mm square post profiles, making it suitable for improving fence line presentation where open ends need fast and consistent coverage.
The 1.80mm wall thickness gives the cap a practical balance of grip and durability for standard fencing, landscaping and commercial perimeter work. The defined 18mm x 18mm size helps purchasing teams match the cap to existing post profiles during repairs or installations.
