Although soil pipe is frequently utilised for dust extraction ducting, one problem which often crops up when using it is that the outer diameter of the soil pipe is some 112mm or approximately 4.5". To get around this problem we offer a special adaptor, 900063, to convert from the soil pipe to a 4" hose. Duct Tape (410221) can be used to produce a more secure joint.

Dimensions please...I haven't bought one as like an awful lot of stuff here, there is no detail on the various inside and outside diameters - an all to common trap when building a dust collection system. Please could somebody do a bit of measuring. I'm sure it would increase sales, or at least avoid the frustration of buying something that turns out to fit inside, not outside for example.
