LCC Soil Pipe Strap on Boss BSPT 100mm
CODE S4092 Category

LCC Soil Strap on Boss BSPT 100mm

£107.10 ex VAT (£128.52 inc VAT)

A strap-on boss giving a threaded BSPT connection into an existing 100mm LCC soil stack.

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

The strap-on boss clamps around an existing 100mm cast iron soil pipe and gives a threaded BSPT connection for a small waste or overflow, without cutting the stack or adding a branch.

It is the practical way to add a basin or overflow connection to a surviving stack on a listed building, where replacing a length would disturb original fabric. For new work, a bossed pipe gives the same connection as part of the run.

Size: 100mm (4″) pipe, with a 1¼″, 1½″ or 2″ BSPT boss.

Part of our Traditional LCC soil system to BS 416-1:1990, finished in black to match the pipework.

Suitable for listed buildings and conservation area work. For specification advice, a full schedule or a quotation, call 0333 987 4452 or use the contact form.
