Gliding piano castor cups offer protection for all hard floor types and allow you to move the piano so that you can clean behind it or reposition the piano within a room.
Single thickness felted cups are available to buy from this site, or from my ebay listing.
Universal double felted cups are listed separately on ebay. See below for the variations to suit your piano castors.
1) Doubled felted with concentric holes.
2) 3 sizes of centre hole to match the size of your castors.
3) Mixed size castors.
Choose this universal castor cup if you are not sure of the castor sizes and for extra protection.
The smallest hole is 12mms, suitable for a castor diameter measuring under 26 mms.
The medium 16 mm hole is suitable for a castor diameter measuring 26 - 35 mms.
The largest 20 mm centre hole is suitable for a castor diameter measuring 35 - 50 mms.
These gliding piano castor cups measure 60 mm in diameter and are adapted for upright pianos.
They provide an inexpensive and effective solution to two problems:
1) The piano castors should not make direct contact with a wooden floor.
2) You may need to move the piano without damaging the floor. These cups allow you to clean behind the piano, or to move it within a room.
I carry packs on the van for you to buy when we deliver your piano.
The castor cups have an outer diameter of 60 mms and inner well diameter of 45 mms.
The castors' size should not exceed diameter 50 mms or 44 mms in width.
The well of the cup is lined with stiff 4 mm felt and provides an effective cushion, while the centre hole gives purchase to stop the castor rolling out of the cup.
Select the correct size of centre hole to fit your castor. The correct size of centre hole allows the castor to grip the felt and spread the piano's weight.
Tip 1: Ensure the floor is clean and free from dirt and grit before moving the piano.
Tip 2: Even when using sliding cups, never be tempted to manoeuvre a piano alone:
Two people are necessary because the first thing you need to do is to each stand at opposite ends of the piano, with a hand each between the top left and right corners of the lid and the wall. Slide the piano one end at a time, little by little, away from the wall, noting that when one end comes out the other end will try to move into the wall, stopped by your hand pulling it away.
