The complete guide
Matching the right external stop end to your gutter profile — FloPlast 112mm Half Round Gutter External Stop End, Black
Guttering parts are not universal across brands or profiles — a 112mm half round fitting only seats correctly on the matching system. Before ordering, measure the existing gutter's internal width and check whether it's half round, square line or a deep-flow profile, since the FloPlast 112mm Half Round Gutter External Stop End, Black is manufactured to the 112mm half round standard and won't bridge a mismatched size.
