This article is about a specific device from A L Enterprises. Click here to see general notes about their range of devices.
The Curve was released at about the same time as the CB3000. It is similar in style to the CB3000 except that it is larger and the tube is curved to accomodate a larger cock than can be comfortably secured by a CB3000.
The Curve is approx 35mm internal diameter, 115mm along the top, 65mm along the bottom (giving an average of 90mm shaft length along the centre of the curve
My experience is quite similar to my experience with my CB3000, see my comments here.
