Who the PB312 Cornet Case is For

The Protec PB312 is a protective carrying case for most Bb cornets, designed for players who want a secure, instrument-specific fit with practical storage for daily rehearsals, commuting, and gigging. Its patented PRO PAC approach pairs a lightweight wood frame and padded, non-abrasive lining with a traditional vertical slot-load layout that envelops the instrument to help reduce movement and impact risk.

This model is especially suitable for working musicians and students who carry a cornet frequently: it includes rope handles (main and subway), an adjustable shoulder strap with a non-slip pad, a large gusseted front pocket with built-in organizer, and double mouthpiece cups. A removable padded block accommodates different cornet lengths, and features like rubber feet, rubber corner runners, durable metal hardware, and lockable zipper pulls (lock hole on main compartment) are built for consistent transport use.

Common Questions about the Protec PRO PAC Cornet Case

Will the Protec PB312 fit my cornet?

The PB312 is designed to fit most cornet makes and models. For best results, compare your instrument to the interior horn section dimensions (16.5 x 4 x 7.5 in) and confirm your bell diameter is 5.5 in or smaller.

What makes the PB312 different from a standard wooden cornet case?

The PB312 uses a lightweight, shock-absorbing wood frame inside a weather-resistant ballistic nylon exterior, aiming to reduce carry weight while adding gig-bag-style storage such as a large front pocket with an organizer and dedicated mouthpiece cups.

Does the PB312 include features for commuting and quick handling?

Yes. It includes rope handles (including a subway handle), an adjustable shoulder strap with a non-slip pad, rubber feet for stable placement, and QuickLock that lets you close an empty case without fully zippering.
