When it comes to conventional guttering, you might think a bigger roof area needs a bigger gutter.
But at OSMA, we think a more efficient Running Outlet is the smarter solution.
The advanced hydrodynamic running outlet has a unique wider aperture, capable of handling up to 30% more rainwater when compared with other outlets of a similar size.
Extra wide seals allow for thermal expansion and provide a secure watertight joint. The innovative Flexiclips make installation easy and can be removed to adjust the system or clean a seal.
Plus the unique cloaking collar has been designed to conceal the down pipe cut ends, for a much neater appearance.
Available in a range of 6 profiles… and a choice of colours.
OSMA. The benchmark for Running Outlets.
