Rectangular Pipe to Round Connector

£160.61 – £240.02Price range: £160.61 through £240.02 +VAT

Clear

The Rectangular Pipe to Round Connector provides a transition fitting between a cast iron rectangular downpipe and a cast iron round downpipe, allowing the two pipe systems to be joined cleanly in a single run. Used where a rectangular pipe at the upper part of the elevation transitions to a round pipe — for example where the rectangular section connects to a round underground drainage system, or where an existing round pipe is being connected to a new rectangular installation above.

An important practical fitting on heritage restoration projects where the existing above-ground pipe is rectangular and the below-ground or transition pipework is round. Manufactured in cast iron to BS 460:2002. Available in sizes to suit the standard rectangular pipe range. For specification support, call 0333 987 4452.

The Paxton H82 is a large-format hopper with decorative collar mouldings, making it particularly well suited to late Victorian and Edwardian buildings where the rainwater system forms part of the architectural composition. Typical applications include commercial heritage buildings, civic buildings, large detached houses, institutional premises, and warehouse conversions where a more substantial fitting is appropriate.

What building types is the Iron Works Hit & Miss Vent in Polished Brass suited to?

The Polished Brass finish suits buildings where brass metalwork was standard — formal Victorian terrace housing, civic and institutional buildings, and high-quality estate architecture. It is appropriate on listed buildings and conservation properties where the wider ironmongery specification is in brass and a matching material is required.

What is the difference between satin chrome and polished chrome rooflight openers?

What is the difference between satin chrome and polished chrome rooflight openers?

Satin chrome has a brushed, low-sheen finish suited to contemporary interiors, while polished chrome has a bright mirror finish. Both are available in the telescopic hand winder range at Tuscan Foundry. The choice typically depends on the existing ironmongery specification.
