This listing is for two black flexible Reel to Reel  spool holders/retainers designed and made in the USA.  These are flexible enough to allow for easy placement and removal with no hassle.  The center hole is 1/4 of an inch in diameter. 

Please watch for additional colors and styles soon.  Looking for flexible or rigid replacement parts?  Tell me what you need.  I can create small items in plastic or rubber to solve your problem or replace hard to find parts. 

Please ask any questions prior to purchase.
