RB502 – Fascia Rise and Fall Bracket for Plain Half Round Gutter

The RB502 is a fascia-mounted rise and fall bracket for plain half round cast iron guttering. Where a standard fixed fascia bracket cannot provide precise fall control — on older properties with uneven fascia lines, long gutter runs, or where the gradient needs to be set independently of the fascia angle — the RB502’s adjustable rise and fall mechanism provides the solution.

The bracket features a galvanised steel fascia plate with a threaded rise and fall cup that allows the gutter to be set at the correct fall at each fixing point. This eliminates shimming and packing and allows accurate gradient setting across the full length of the run. Available in four sizes to suit standard cast iron half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).

Commonly specified on listed building and heritage conservation projects where cast iron half round guttering must perform correctly over long runs or where the existing fascia line is not straight. The RB502 is also compatible with Osma, Marley, and other standard half round gutter systems, making it a practical choice for mixed or replacement installations.

Used on residential and commercial heritage buildings, country houses, churches, and institutional properties where precise drainage fall is essential and the fascia fixing point is available.

Compatibility: Cast iron half round gutter profiles 100mm, 115mm, 125mm, and 150mm. Also compatible with Osma and Marley half round systems. For project specification, call 0333 987 4452.
