3mm Aluminium Coping – Stopend Upstand (Right Handed) | 100mm External Leg

Finish coping runs neatly with a durable stopend designed to seal and protect left-side wall edges.

This right-handed stopend upstand is used to complete the end of sloping aluminium coping runs, delivering a clean, watertight finish on parapet walls. Fabricated from strong 3mm 1050A-grade aluminium, it's built to last while maintaining a consistent profile with your existing coping system. The 100mm external leg provides balanced wall coverage, and the powder-coated finish resists corrosion, UV, and wear making it ideal for long-term performance on both modern and traditional builds.
