The 112mm Square Rainwater Gutter External Stop End (Black) is a vital terminal component designed to seal off the end of a square-profile gutter run securely. Manufactured from high-grade, durable uPVC, this fitting caps the open edge of the guttering to prevent water from spilling over the side of the building and directs all collected runoff safely toward the designated running outlets.
 
Featuring a precision-molded internal profile that matches standard 112mm square guttering, the stop end includes a secure clip-on or slide-on mechanism backed by an integrated rubber sealing gasket. This ensures a completely watertight barrier that remains stable against wind pressure and heavy water loads.
 
Manufactured to high industry standards, the UV-stabilized black uPVC material resists fading, weathering, and structural degradation caused by prolonged exposure to sunlight and harsh environmental conditions. It delivers a clean, professional finish and a long-lasting, low-maintenance solution for completing roof drainage networks on residential and commercial properties.
