The RB501DH is a zinc-plated side rafter rise and fall bracket for plain deep half round cast iron guttering. Where there is no fascia board — on open eaves, timber-framed buildings, or structures where rafter-face fixing is preferred — the RB501DH provides a secure, adjustable support mounted directly to the side face of the rafter.

The bracket features a zinc-plated steel rafter arm for side-face fixing, combined with a threaded rise and fall cup that allows gutter fall to be set precisely at each bracket position. Available in four sizes to suit the standard range of deep half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).

Typically specified on heritage and conservation projects involving deep half round cast iron guttering where the roof construction dictates rafter-face rather than fascia fixing. Also used on refurbishment projects where the original fascia board is absent, damaged, or structurally unsuitable as a fixing surface.

The rise and fall cup allows precise gradient control along the gutter run regardless of rafter angle, eliminating the need for shimming or packing. Zinc-plated finish for outdoor corrosion resistance.

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

FAQ Categories

All FAQ
Which bracket should I use for deep half round cast iron guttering?
The choice depends on your roof construction. Fascia brackets fix to the front face of the fascia board. Drive-in brackets pass through the fascia for a concealed fix. Side rafter brackets fix to the rafter face where no fascia is present. Top rafter brackets fix to the rafter top surface on open eaves. Rise and fall variants allow gradient adjustment on uneven fascia lines or long gutter runs. All brackets for the deep half round gutter are dimensioned specifically for its wider and deeper profile.
Are deep half round gutter brackets interchangeable with standard half round brackets?
No. Deep half round gutter brackets are specifically dimensioned for the wider and deeper cross-section of the deep half round profile. Standard half round brackets will not provide the correct support geometry. Always specify brackets from the deep half round range when working with deep half round guttering.
Do cast iron deep half round gutter brackets need a protective coating?
Zinc-plated and galvanised steel brackets have a protective coating applied at manufacture. Cast iron brackets are supplied factory-black and should be maintained with linseed oil paint or conventional metal paint to prevent corrosion. Regular inspection and painting is the key to long service life.
