SKU FTB300-3M Category Tag


The B300 is an up-stand trim, fitted to contain and direct the flow of water to a gutter, its extra depth is well-suited to use on a warm roof to allow for deep gutter penetration. The B300 will match the drip profile of an A250 when used on an adjoining edge.

A single batten is fixed level with the top edge of the deck. Apply 30mm beads of trim adhesive to the batten at 300mm centres, rub the trim into place and nail through the top of the trim into the decking.

Do not nail through the front of the trim, instead where the trims are overlapped, they should be bonded together with a thin strip of PU adhesive on the inside of the overlapping trim. If a ladder is likely to be leant against a B-type trim for access to the roof, the trim will need to be reinforced to avoid deformation.

The trim can either be doubled up by slotting a section of extra trim within the section where the ladder will be used or it can be reinforced by being coated with a layer of GRP laminate and then tissue to maintain a smooth finish. Alternately, a wooden batten can be shaped and fitted into the ridge of the trim to ensure that it remains rigid.
