Hammer UPVC Gutter Outlet, 110mm Downpipe Connection, UV-Stabilized

Hammer Square Gutter Outlet

The Hammer Gutter Outlet serves as the primary transition point between horizontal roof guttering and vertical rainwater downpipes. This heavy-duty UPVC fitting ensures high-velocity water discharge during intense rainfall while maintaining a watertight seal across the drainage network.

Built for the Job

Site supervisors and roofing contractors specify this drainage component for its reliable performance in tropical climates. The unit features a drop-out throat designed to minimize turbulence, allowing water to exit the horizontal run quickly to prevent gutter overflow. Its square profile matches standard residential and commercial gutter systems common in Kenyan construction projects. The material resists corrosion from acidic rainwater and remains stable under direct sunlight, preventing the brittleness often seen in lower-grade plastics. Installers appreciate the deep sockets that allow for secure solvent welding or rubber seal integration, depending on the specific system requirements.

• Residential roof drainage systems requiring 110mm downpipe integration.

• Commercial warehouse guttering for high-volume water management.

• Industrial site rainwater harvesting setups using UPVC piping.

On-Site & Workshop Notes

• Ensure the horizontal gutter has a slight fall toward this connection point to prevent standing water.

• Apply a high-quality PVC solvent cement if a permanent chemical weld is required for the downpipe joint.

• Regularly clear the intake area of the fitting to prevent leaf buildup from obstructing the vertical flow path.

• Check compatibility with existing gutter brackets to ensure the weight of the water-filled outlet is properly supported.
