I'm Howard Gustafson and I've been servicing pianos full time since I was 17 years old (I'm over 50 now) and during that time I have serviced/replaced casters on hundreds of pianos - antique uprights, spinets, consoles, studios, square grands, baby grands and grands.  I have the experience and knowledge to answer questions about this product or work through a difficult installation before or after the sale (like when the piano is tipped over in the middle of the living room) - Your success at using and recommending my products and services is very important to me so my contact info is included in each shipment and you can also reach me through eBay.
