Yep, been using one for a while. The cane from an easy siphon fits through the middle outlet and it makes transfers from a glass 23 litre carbuoy quick and easy.
If it is one of the stainless racking canes it will fit no problems.
TIP : Go to a bearing retailer and buy some food grade silicone spray. Fit the racking cane into the cap and then spray the part of the cane that will be outside the cap, this will help it slide readily through the cap.
