The wooden pipe bobbin spacer is used to hold a cast iron downpipe away from the wall surface at a controlled distance of 40mm. The bobbin is fixed to the wall and the pipe sits within or against it, creating a consistent and stable standoff along the full length of the pipe run. This standoff allows air to circulate behind the pipe, reducing the risk of damp penetration, condensation, and the accelerated corrosion that can occur when a cast iron pipe sits directly in contact with a masonry wall.
A practical maintenance and conservation detail on period and listed buildings — ensuring the downpipe runs clear of the wall face extends the life of both the pipe and the masonry behind it. Suitable for use with round and rectangular cast iron downpipes. Supplied individually. For specification support, call 0333 987 4452.

Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.
The opener is designed for use with Lumen Rooflights and compatible timber-framed skylights. The telescopic shaft and adjustable mounting bracket allow it to be fitted to a range of rooflight frames. If you have a specific rooflight model, call us on 0333 987 4452 to confirm compatibility.
Cast iron radiators cost no more to run than modern steel or aluminium radiators. Cast iron is a very efficient material at emitting heat, thus you have items like le creuset cast iron pans. Cast iron holds it’s heat extremly well, which means that the radiators stay warm for longer.
The Antique Black finish is cast iron with a blackened surface — the most historically accurate finish for cast iron ironwork and the most appropriate for the majority of heritage applications. Polished Lacquered is cast iron with a bright polished surface sealed with clear lacquer, suited to interiors and sheltered locations where polished ironwork is the specification. Polished Brass is solid polished brass throughout — the correct choice where existing building fittings are in brass or where a warm metal tone is required.
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.
