Check my eBay store for other sizes of grand casters and vertical casters too.I've been servicing pianos full time since I was 17 years old (30+ years) and in that time have serviced/replaced casters on hundreds of pianos - antique uprights, spinets, consoles, studios, square grands, baby grands and grands. I'm glad to answer questions about this product before or after the sale - my contact info is included in each shipment and you can also reach me through eBay.
