Drive belt identification is HTD 180-3M meaning that the item is a High Torque Drive with a pitch length of 180mm and an individual tooth pitch of 3mm. The (round topped) tooth height is 1.6mm and total belt thickness is 2.4mm. Width is 6mm. This item is suitable for the Vax Air Cordless Solo model indicated elsewhere and may fit other Vax units but I can't confirm this and hence my inclusion of the full dimensional details of the belt. If you decide to purchase this for a cleaner that isn't the fitment I have indicated, please double check it will totally suit your application before ordering.
