For replacement of damaged, weak, broken or missing jack springs in most full size upright pianos. (If you're repairing a spinet or console with a compact action and shorter springs, look for the shorter springs in my eBay store, item #292018728854).

 When measuring your old springs take note that the length may seem shorter from being compressed over the decades. These are made from 0.018" diameter wire, and are 1" long. 12 pieces.

I've been a full time piano technician for 30+ years and am glad to help answer questions before or after the sale.  My contact info is included in each shipment and you can also reach me through eBay.
