Fits perfectly onto other McAlpine components. Needed it in a hurry and my local Tool Station had one in stock.

Don't assume that this will fit where you need it on a McAlpine waste system

Bought this to extend the horizontal section of a McAlpine two sink waste kit only to find it is not compatible with the joint I was wanting to extend. It's only good for extending vertically adjacent to the trap. Had to return this and use a straight compression connector instead.

Great item great price

Recently changing a sink waste trap which had an appliance adaptor which leaked and needed a short piece of pipe, this was the perfect fit, ordered on line and drove to Toolstation Scarborough where my order was ready and waiting saving me time in not having to queue
