The RB501COG is a side rafter rise and fall bracket for the common ogee cast iron gutter. Where there is no fascia board — on open eaves, or where the rafter face is the only available fixing point — the RB501COG mounts directly to the side face of the rafter and provides adjustable support at the correct height for the common OG gutter run. The bracket cup is shaped for the ogee S-curve profile.
The threaded rise and fall cup allows precise fall setting at each bracket position independently of the rafter pitch, eliminating shimming and packing on long runs or where the roof line is uneven. Available in three sizes to suit the standard common ogee range: 100mm (4″), 115mm (4.5″), and 125mm (5″).
Also compatible with common ogee guttering manufactured by Osma, Marley, Hunter, and Lindab, making it a practical bracket solution on mixed or partial replacement installations. Specified on listed buildings, heritage conservation projects, and period properties across England and Wales where the common ogee is the correct profile.
Compatibility: Common ogee gutter 100mm, 115mm, 125mm. Also suits Osma, Marley, Hunter, and Lindab common OG. For specification support, call 0333 987 4452.

Victorian properties most commonly used Ogee (OG) gutter profiles, including the standard Cast Iron Ogee and the G46 Moulded Ogee. Half Round guttering was also widely used, particularly in the later Victorian period. The correct profile depends on what is already present on the building — we recommend inspecting any surviving sections and matching the profile, size, and socket direction exactly. We supply 19 standard gutter profiles and can copy-cast any non-standard profile from a drawing, photograph, or physical sample.
