Rectangular Pipe Branch (Single)

£442.70 – £783.10Price range: £442.70 through £783.10 ex VAT (£531.24 – £939.72 inc VAT)

Cast iron single branch for rectangular downpipes, 100x75mm to 150x100mm, 92.5°, 112.5° or 135°, in primer or black painted finish.

Clear

UK delivery from £30. Fittings are despatched boxed. See delivery rates.

The Rectangular Pipe Branch (Single) joins a second downpipe into a main rectangular run, so two roof areas can discharge through one pipe and one gully.

Branches are made at 92.5°, 112.5° and 135°. The shallower angles give a smoother entry and are often preferred where a branch collects from a second hopper head or a balcony outlet.

Check that the combined flow suits the pipe size, particularly on larger roofs, and allow for a gully or drain connection sized for the total flow.

All fittings in our rectangular range are cast iron to BS 460:2002, made to the same moulded profile so pipes and fittings line up neatly on the elevation. Every fitting is supplied either in primer, ready for painting on site, or in factory black. For listed buildings and conservation areas we also offer hand-applied linseed oil paint in heritage colours, which stays breathable and flexible and is straightforward to maintain. Stocked items are usually dispatched within 5 to 7 working days; allow around 6 to 7 weeks where a linseed oil finish is specified.

Rectangular pipe sizes: 100mm x 75mm (4″ x 3″), 125mm x 70mm, 125mm x 100mm (5″ x 4″) and 150mm x 100mm (6″ x 4″).

Suitable for listed buildings, conservation areas and heritage restoration. For specification support or a project quotation, call 0333 987 4452.
