Half Round Gutter Internal Stopend - Black

Half Round Gutter Internal Stopend - Black

The Half Round Gutter Internal Stop End is a specialized drainage component used to seal the end of a gutter run that terminates against a fitting, such as a running outlet or a 90° angle. Unlike an external stop end, which caps off a raw length of gutter, the Internal version is designed to fit directly into the socket of another gutter fitting to provide a watertight closure.

Manufactured from high-impact, UV-stabilized PVC-u, this component features a pre-fitted rubber seal and a "snap-fit" clip mechanism to ensure a leak-proof termination without the need for additional sealants.

Key Features and Specifications

Profile: Half Round (Compatible with standard 112mm / 114mm residential systems).

Design: Plug-in style (Male) for insertion into the socketed end of gutter fittings.

Seal Technology: Includes a high-grade EPDM rubber gasket for a durable, watertight compression seal.

Material: UV-stabilized PVC-u to prevent fading and brittleness caused by sunlight exposure.

Jointing: Integral "Snap-Fit" clip ensures the stop end remains securely in place under water weight and thermal expansion.

Finish: Gloss Black, matching standard black guttering, fascia brackets, and downpipe systems.

Common Applications

Outlet Termination: Sealing the end of a gutter run where the running outlet is the final component in the line.

Corner Termination: Closing off a gutter system immediately after a 90° or 135° corner fitting.

Restricted Runs: Ideal for terrace or semi-detached properties where the guttering must terminate precisely at a boundary line fitting.
