Size and colour
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.
Design features
- 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, Wavin fittings have been engineered with concealed sockets to hide roughly cut downpipe ends.
- Expansion line and stopper for a secure and reliable installation.
