The FloPlast RK1B black half round gutter fascia bracket screws directly on to the fascia board resulting in a secure fixture of 112mm half round guttering. The bracket is screwed to the fascia board using two countersunk screws (5 x 25mm or 5 x 30mm). The gutter is then clipped in place by first sliding the back edge in under the rear clip and pulling gently down on the front edge to clip the gutter into position. Manufactured from low maintenance uPVC. Practical and easy to install. Suitable for gutter width: 112mm, gutter depth: 52mm.
