CODE RTAP Category

Cast Iron Rectangular Access Pipe

Price range: £393.40 through £664.10 ex VAT (£472.08 – £796.92 inc VAT)

Cast iron access pipe with bolted rectangular inspection door for rectangular downpipes, 100x75mm to 150x100mm, eared or un-eared, primer or black painted finish.

UK delivery from £45. Longer items are despatched palletised. See delivery rates.

The Rectangular Access Pipe is a short cast iron pipe length with a bolted rectangular inspection door, giving a point in the downpipe run where blockages can be cleared without dismantling the pipe.

Access pipes are usually fitted near the foot of a run, above a shoe or gully, or below a hopper head where leaves and debris collect. The door is sealed and bolted, and sits on the face of the pipe for easy reach.

Choose eared, with fixing ears on the socket, or un-eared to match a run fixed with holderbats or earbands.

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.

FAQ Categories

All FAQ
What is a cast iron access pipe used for?
An access pipe is a short downpipe section with a bolted inspection door. Removing the door lets you rod or flush the pipe to clear leaves and silt without dismantling the run. Stand clear when opening it, as water held above a blockage may release.
Where should access pipes be fitted on a downpipe?
At the foot of each stack above the shoe or gully, directly above offsets and bends, and below hopper heads where trees overhang the roof. On tall or long runs, an extra access point part-way up makes clearance easier.
Do I need an eared or plain access pipe?
Match the rest of the run. Eared access pipes are nailed to the wall through cast ears, like eared downpipe lengths. Plain access pipes suit runs fixed with holderbats or earbands.
Are cast iron access pipes suitable for listed buildings?
Yes. Cast iron access pipes to BS 460 are the like-for-like choice for listed and period buildings, and fitting access points avoids damaging historic pipework when clearing blockages. We recommend confirming any changes with the conservation officer.
How do I get a price for a cast iron access pipe?
