Inquiry (采购产品): Invention Hello, my name is Bradley Weis I have recently went into patent pending status for an invention that will make paint edging easier & more efficient. The invention is based on a ball, bearing or ball transfer that references the ceiling or adjacent surface. There is also a separate ball, bearing or ball transfer to ensure the device is square. The main ball transfer unit that installs on the end of a standard roller frame has multiple balls which give you the ability to edge around trim as low as 3/8 of an inch. The main ball transfer unit is removable to avoid paint contamination when applying paint to the roller cover. The whole concept is based on the principle that a ball can move in any direction it needs to which allows the roller to roll & maintain a reference. This invention can only be used with a foam roller cover due to the 90 degree edge that these provide. Please contact me if you are interested, my contact info is as follows. Thank you for your time… Bradley D. Weis 1552 Bluestem ln.
