Who the PB307D Double Clarinet Case Is For
The Protec PB307D is a double clarinet case designed to transport one Bb clarinet and one A clarinet with structured protection and organized storage for accessories and music. It is for players who routinely switch between A and Bb clarinets in rehearsals, pit work, studio sessions, lessons, and performances and want a single carry solution rather than two separate cases.
What distinguishes the PB307D within double-clarinet cases is its PRO PAC design approach: a lightweight shock-absorbing frame, a weather-resistant ballistic-nylon exterior, and a pocket layout that supports real-world professional needs. The interior includes dedicated double-barrel storage (two barrels per clarinet, four total) plus a small accessory compartment for items like cork grease or a swab. Carry options include a padded handle wrap, durable rope handles (including a subway handle), and an included shoulder strap with strong metal clips.
Common Questions About the Protec PB307D
Will the Protec PB307D fit my Bb and A clarinets?
The PB307D is designed to fit most Bb clarinet makes and models and most A clarinet makes and models. If your instruments have unusual keywork, oversized bell geometry, or aftermarket accessories that change the profile, confirm measurements against the case’s overall dimensions or contact us for fit guidance.
How much storage does the PB307D have for accessories and sheet music?
It includes a large gusseted front pocket for accessories, a built-in organizer with three pen sleeves and two zippered pockets, and a rear sheet-music pocket sized to hold 8.5 x 11 in paper. Inside, it also provides double-barrel storage for up to four barrels total and a small compartment for items like cork grease or a swab.
Is the PB307D built for daily commuting and travel?
Yes. The exterior is durable 1680 ballistic nylon, the frame is designed to absorb shocks while staying lightweight, and the case uses strong metal hardware, custom zippers (with a lock hole on the main compartment), and sturdy rubber feet. QuickLock allows you to secure the case when empty without fully zippering it.
