20mm x 20mm Square Fence Post Cap | White Polyethylene
This square fence post protector is shaped for 20mm x 20mm square post profiles, making it suitable for covering sharp or unfinished post tops where open ends need fast and consistent coverage.
Polyethylene gives the cap a durable, weather-ready construction for outdoor use, helping reduce exposure to rainwater, grit and daily knocks. The cap supports a cleaner finish on visible fencing where exposed post ends would otherwise look unfinished.
What Are Square Fence Post Caps?
