115mm Black Hi-Cap to Half Square Gutter Adaptor allows Hi-Cap gutter to be adapted to or from traditional plastic Square Line gutter. This fitting enables FloPlast Deepflow gutter (or any other deepflow system compatible with FloPlast) to be connected to a standard 114mm FloPlast square gutter without the need for any kind of sealant. This fitting is not handed as both square and half round gutters are symmetrical.
