Clear

The RB500DH is a zinc-plated top rafter rise and fall bracket for plain deep half round cast iron guttering. Where open eaves construction or the absence of a fascia board requires fixing directly to the top surface of a rafter, the RB500DH provides a secure and adjustable support that allows precise fall setting along the gutter run.

The bracket features a zinc-plated steel rafter arm designed for top-surface rafter fixing, combined with a threaded rise and fall cup that adjusts the gutter height at each bracket position independently of the rafter pitch. Available in four sizes to suit all standard deep half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).

Commonly specified on listed building and heritage restoration projects involving deep half round cast iron guttering, and on new construction where exposed rafters and open eaves are a feature of the design. The rise and fall mechanism eliminates the need to pack or shim the bracket, allowing accurate gradient setting across long gutter runs or on complex roof lines.

Zinc-plated finish provides corrosion resistance for outdoor use. The RB500DH is the deep half round equivalent of the RB500 bracket, dimensioned specifically for the wider and deeper profile of the deep half round section.

Compatibility: Plain deep half round cast iron gutter profiles 100mm, 115mm, 125mm, and 150mm. For project specification, call 0333 987 4452.
