The B300 Roof Trim for Fibreglass Roofing is fitted to the edge of the flat roof to prevent water run-off. The depth of this drip matches the A250 Drip Trim and is usually used in a warm roof configuration. This trim is also compatible with the C1, C2 and C4 corner trims. 

We also offer B260 Trims and B230 Trims which match with our A trims and corners.
