The 112mm Square Rainwater Gutter Internal Stop End (White) is a specialized terminal component designed to cap off a square-profile gutter run from the inside, typically used in tight spaces, corner applications, or internal architectural layouts where external caps are impractical. Manufactured from high-grade, durable uPVC, this fitting seals the open channel to prevent water overflow and direct runoff safely toward designated outlets.
 
Featuring a precision-molded internal profile that fits snugly within standard 112mm square guttering, the stop end works alongside integrated rubber sealing gaskets or structural adhesives to form a secure, watertight barrier. Its compact design allows it to sit flush within the run while maintaining strong resistance against shifting wind pressure and heavy water loads.
 
Manufactured to high industry standards, the UV-stabilized white uPVC material resists fading, yellowing, and structural degradation caused by prolonged exposure to sunlight and harsh weather conditions. It delivers a clean, professional finish and a long-lasting, low-maintenance solution for completing complex roof drainage networks on residential and commercial properties.
