The ARP Aluminium Coping T Junction is designed for contractors and homeowners looking to create a professional, watertight finish at the intersection of three wall sections. This high-quality component provides a seamless transition for wall thicknesses between 141mm and 200mm, effectively shielding your masonry from water ingress and long-term structural degradation. While it offers superior durability and a sleek aesthetic in anthracite grey, precise measurement of the wall width is essential to ensure a correct and secure fit.

No, this specific component is engineered for wall thicknesses between 141mm and 200mm. Using it on walls outside this range will result in an improper fit and potential water leaks.
Fixings are typically sold separately to ensure they match the specific substrate of your wall (e.g., masonry versus timber frames).
While the powder-coated finish is durable, painting over it is not recommended as it may void the finish warranty and degrade the long-term weather resistance.
Always apply a high-quality, compatible external-grade sealant along the joints where the coping sections meet the T-junction.
Yes, aluminium is naturally corrosion-resistant, making this an excellent choice for coastal environments where traditional metals might rust.
Check that the underlying wall surface is not uneven; use shims if necessary to ensure a level mounting surface.
Verify that the coping run has a slight fall or slope to encourage drainage away from the T-junction.
For proper installation, ensure the wall surface is clean and level before placing the coping junction. Use the appropriate fixings to secure the unit, ensuring that all joints are sealed with high-quality, neutral-cure silicone or butyl tape to maintain a watertight seal. This component is compatible with standard ARP aluminium coping systems within the 141mm to 200mm width range. Care for the product is minimal; routine inspection of sealants once a year and a simple wipe-down with mild soapy water will keep the anthracite grey finish looking like new for decades.
