Top rafter rise and fall bracket for half round cast iron guttering. Our zinc plated
top rafter rise and fall gutter bracket is available in the following sizes:
100mm (4″)
115mm (4.5″)
125mm (5″)
150mm (6″)
The RB500 is a zinc-plated top rafter rise and fall bracket for plain half round cast iron guttering. Where a fixed bracket is not appropriate — on open eaves, cut roof constructions, or where the rafter provides the only available fixing point — the top rafter bracket provides a secure, adjustable support mounted directly to the top surface of the rafter.
The bracket features a zinc-plated steel rafter arm for top-surface 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 all standard cast iron half round gutter profiles: 100mm (4″), 115mm (4.5″), 125mm (5″), and 150mm (6″).
Suited to new construction with exposed rafters, heritage restoration projects where a continuous fascia board is absent, and any situation where top rafter fixing is structurally preferred. Commonly specified alongside cast iron half round gutter sections and angle fittings on period and listed building projects where precise fall control is critical to long-term performance.
The rise and fall mechanism eliminates the need to pack or shim the bracket, allowing accurate gradient setting across long gutter runs on uneven or complex roof lines. Zinc-plated finish provides corrosion resistance for outdoor use.
Compatibility: Cast iron half round gutter profiles 100mm, 115mm, 125mm, and 150mm. For technical queries or project specification support, call 0333 987 4452.

Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.
Yes. Decorative cast iron and brass ventilation grilles of this pattern were widely used in Victorian and Edwardian buildings, and like-for-like replacements are generally accepted by conservation officers for listed building works. We can provide product specifications and material details to support listed building consent applications if required.
The Brass Rooflight Pole Winder Opener 300mm is a screw-jack operated rooflight opener designed for manual control of timber-framed skylights and Lumen Rooflights. The 300mm fixed arm is suited to standard rooflight positions and is finished in polished brass.
The handle is compatible with Lumen Rooflights and most pole-operated rooflight and skylight systems. If you are unsure whether it suits your specific rooflight, call us on 0333 987 4452 and we can advise.
Yes. Cast iron rainwater goods are widely accepted by conservation officers and historic environment bodies as the appropriate material for listed buildings. Tuscan Foundry's hopper heads are manufactured in solid cast iron to BS 460 specification and are suitable for all listed building grades. A linseed oil paint finish is also available, which is particularly appropriate for conservation projects.
Prices for rooflight openers are shown on the product pages at tuscanfoundry.com. For volume orders, project pricing, or compatibility queries, please call 0333 987 4452 or use the contact form on our website.
For rooflights directly above a worktop or sink, a telescopic screw-jack hand winder is the most practical choice. Available in polished brass, satin chrome, and polished chrome, these openers allow controlled ventilation from a fixed handle position without requiring a pole. The 150mm or 250mm size is typically appropriate for standard-height kitchen rooflights.
The H460 accepts round pipe connections in 65mm, 75mm, and 100mm diameters. Square pipe connections are available in 75×75mm, 100×100mm, and 125×125mm. Rectangular connections include 100×75mm, 125×100mm, and 150×100mm options. Connection type is selected at the point of order.
The Gothic foliate tracery design of the Ornamental Airbrick provides a good free-flow ventilation area relative to its face size. The open area is comparable to other standard cast iron airbrick patterns. The visual density of the pattern at a distance reads as solid ironwork, which suits formal and decorative elevations without compromising subfloor ventilation effectiveness.
