RoundLine is a 112mm (4½") half-round domestic gutter system with circular 68mm downpipe available in black, white, brown and grey colour options.
Ease of installation
RoundLine is fitted with a ‘Flexiclip’ seal jointing mechanism, making it easy to connect gutter to fittings. Because the clip is flexed, rather than the whole component, this ensures a positive, permanently watertight joint.
For outstanding flow performance RoundLine features an hydrodynamic outlet to handle more rainwater than similarly sizes competitive systems.
Using specialist seal technology our wide, retained seals provide a secure, watertight fixture with the flexibility to allow for thermal expansion.
For an aesthetic pleasing finish, Osma fittings have been engineered with concealed sockets to hide roughly cut downpipe ends.
Expansion line and stopper for a secure and reliable installation.
