3mm Aluminium Coping – Closed Stopend | 75mm External Leg

Finish your coping system cleanly with a durable stopend that seals and protects.

The 3mm Aluminium Closed Stopend is built to seal the end of flat coping runs on parapet walls and terraces. Made from premium 3mm 1050A-grade aluminium, it offers a clean, modern finish while providing excellent protection against rain, wind, and wear. The polyester powder-coated surface resists corrosion and UV fading, and the 75mm external leg provides standard wall coverage ideal for residential, commercial, and industrial flat roof applications.
