Our ogee cast aluminium gutter lengths are a lightweight alternative to the traditional styled cast iron ogee guttering. This 1.8mtr length measures 125mm across the top, is 100mm deep and is made from a top quality aluminium alloy.When joining cast aluminium gutter lengths to unions and other fittings, the process must be completed by injecting ARPand#039;s unique 3923 sealant after said fittings have been clipped into position in order to ensure a secure fit.
