Sold by the foot - two or more feet ordered will be sent as a continuous piece.2" wide, about .055"-.060" thick. Herringbone weave. Used to connect reed organ pump pedals to the exhauster bellows. Also used in player piano restoration to hinge pumping bellows / reservoirs and also to provide strain relief for the reservoir bellows material (before covering the reservior put a piece or two across the open end to limit to desired span - when outward pressure pedal springs are installed the straps will take the tension instead of the bellows cloth).
I've restored player pianos for 30+ years. If you have questions about this product before or after your purchase let me know, I'm glad to help. I include my contact information with each package and you can also reach me through eBay.
