New double wheel piano caster kit for grand & baby grand pianos. Includes 3 Darnell casters, mounting sockets and screws.  Screws are #10, 1.5" long phillips head - the most common size we use during caster replacement.

Wheels are 2" in diameter, 3/4" wide each (for a total wheel width of 1 1/2").  Mounting socket plate is 1 13/16" square with a stem about 1 1/16" tall and about 15/16" in diameter.  Rated for 200 lbs each.

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.
