The Rectangular Pipe Offset Side steps a cast iron rectangular downpipe sideways along the wall, through the narrow face of the pipe, to clear a window, opening or feature while keeping the pipe tight to the wall.

Side offsets are handed. Choose left hand or right hand according to the direction the pipe steps as you face the wall from outside. Each is made as a single casting with two 112.5° bends and a straight between them, giving offsets from 56mm to 610mm. The head carries the moulded socket band, available eared with integral fixing ears, or un-eared for runs fixed with holderbats or earbands.

Where the pipe needs to step outwards from the wall rather than sideways, use the Rectangular Pipe Offset Front.

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.

Can the Iron Works Hit & Miss Vent be used externally?

Can the Iron Works Hit & Miss Vent be used externally?

The Antique Black cast iron version is suitable for external use. The Polished Lacquered version is best suited to interiors or sheltered external locations where the polished finish will be protected from weathering. The Polished Brass version is suited to interior and semi-exposed locations. For external applications on exposed elevations, the Antique Black finish is the recommended specification.

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

The Iron Works Patterned Hit & Miss Vent suits Victorian and Edwardian buildings where decorative cast iron or brass ventilation grilles were part of the original specification — including terrace houses, civic buildings, churches, entrance halls, and estate properties. It is appropriate on listed buildings and conservation area properties as a like-for-like decorative vent replacement, and on new heritage-quality construction where period detailing is required.
