This is the additional stand or prop that is to be used with the radshifter radiator shifting tool found here on ebay, the Rad-stand simply clips onto the back of the radshifter and is used to stand the radiator, or park the radiator in the middle of the room, ie you will not have to move the radiator to a point int the room to lean it against anything. (wall etc)
When used in conjunction with the Radshifter, there is a wheel attached to the stand to allow easy movement of the radiator backwards or forwards.
The Radshifter and stand really makes moving any flat panel radiator a doddle.
Please note, you will need a Radshifter to use the rad-stand described here.
