JBL Supply was founded over 30 years ago by Jerry Larson. Jerry saw others in the kitchen cabinet industry placing spacers in 5 piece doors to help aid in reducing panel rattle as well as reduce cracking glue joints when expansion and contraction take place. Jerry also found quickly that a “GREEN” product was necessary for several reasons. Other products that are still used today contain oil, Carbon black and Phthalates. OIL and Carbon Black can “leach” from the product during compression. This leaves unsightly spots on the beautiful doors. This just would not do for Jerry. The team at JBL Supply has spent many years and thousands of dollars researching these issues and finding a solution to bring to market just for you. We feel our products are far superior to others on the market for many reasons, yet we keep our prices low for our customers benefit. We do not feel you should pay a premium just to use the best product on the market.
