Designed for Serious Trombonists – The PRO PAC Screw Bell Tenor Trombone Case is built to meet the demands of musicians who need top-tier protection and versatility for their cut and screw bell tenor trombones. Engineered with Protec’s legacy of innovation—dating back to the PRO PAC line’s launch and patent in 1984—this case delivers the durability, security, and thoughtful design that musicians trust.  
Inside, modular foam blocks with secure hook-and-loop closures ensure a customized, snug fit for your tuning slide and bell braces. The slide section tucks neatly beneath the bell, while the removable padded bell protector adds an extra layer of security.  
As with all Protec products, this case is responsibly made, with materials rigorously tested to be free of Lead, DEHP, PAHS8, DBP, and BBP—giving you confidence in both safety and sustainability.
