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. 

The reason for the 2nd image in green is to illustrate that because of the curve at the bottom of the trim, the trim needs to be fitted a little out from the wall. We suggest fitting a 2 x 1 to the wall first to keep the trim more secure.
