Excellent setup for the tall, heavy pre-depression upright pianos. Rated for 160 pounds each caster.  Rubber wheels are easier on most floors and won't leave rust stains on carpet. Kit includes bushings for the socket stems (in case existing hole in piano is larger than the 1/2" new stem - very important to prevent breaking socket). Ragland's exclusive ProFit Shims designed ONLY in our facility are also included in the event they are needed to level the piano. Screws are #10 size, 1.5" long - the most common size we use when replacing casters. Original screws are often bent, missing or rusty.  Halfway through the job is NOT the time to find out you need any of these parts!

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.

Let's briefly discuss replacing single wheel casters with double wheel casters.  If the original caster sockets were mounted flush with the underside of the piano this will likely be a fairly straightforward swap.  You'll still need to make sure the back casters won't swivel into the bottom board (it often has cutouts where the casters swivel and since these casters are wider you may have to widen that radius).  If the original casters are mounted in a recess you may have to increase the radius of that recess.  A router works well for that task.  If you don't have access to a router, a fairly inexpensive option is to use a rotary rasp mounted in an electric drill.  A note of caution though!  On pianos with narrow toeblocks AND recessed caster sockets it may be unwise to increase the radius of the caster "well" - sometimes the wood on the sides of the toeblock gets thin or breaks through - in that case I recommend another caster kit I have that has single rubber wheel casters that will not need much routing (if at all).  It's in my eBay store, item number 291683491137.

Another option for dealing with recessed caster sockets is our shim kit - item # 292632738430.  It is a package of shims that will allow you to shim each caster socket anywhere from just .030" all the way to 7/16" - so... no router, no rasp, just add enough shims behind the caster socket to shim it such that the caster won't drag on the piano bottom when rotating and you're done.  I recommend at least 1/8" clearance to account for a bit of flex when weight is put on the piano.  This will add some height to the piano, but if you keep it under 7/16" per caster it should not be an issue.

Caster plates/sockets are 2 1/8" diameter.  The stem that fits up in the piano is almost 5/8" in diameter (.59") and is 1 7/16" long.  The caster wheels are 2" in diameter and a little over 3/4" wide (26/32" to be more precise).  The dual wheel casters are 1 26/32" wide.  The distance from the mounting plate to the bottom of the wheel is about 2 3/4".  The included bushings force fit over the stem and have an outside diameter of .92" - useful when replacing original casters that had a larger diameter stem.  For longevity of the caster socket it's important the stem fits tightly in the body of the piano.
