18mm x 18mm Square Fence Post Cap | White Polyethylene
Specified for equestrian yards sites and similar outdoor projects, this white plastic post cap helps cover unfinished 18mm x 18mm square post ends with a tidy colour-matched finish.
Polyethylene gives the cap a durable, weather-ready construction for outdoor use, helping reduce exposure to rainwater, grit and daily knocks. Its square shape makes it better suited to matching the actual post profile than a generic round-only cap.
What Are Square Fence Post Caps?
A square post cap provides a simple push-on cover for hollow or open-ended square posts. It helps reduce water entry, covers unfinished edges and supports a cleaner appearance across domestic, commercial and agricultural fencing.
Common Applications
- Square post protection for landscaping projects
- Site maintenance where missing post caps need replacing
- Public sector railings and boundary systems
