Designed to fit shallow roundback shaped guitars, the SKB Shallow Roundback Shaped Acoustic Hardshell case incorporates a proprietary engineered rubber-modified Styrene shell and rigid EPS interior foam that cradles the guitar securely and absorbs shock. Molded-in bumpers provide maximum protection for the aluminum valance. The case features SKB???s patented fiberglass reinforced nylon trigger release latching system with the inclusion of a TSA recognized and accepted locking latch. The TSA lock enables you to lock your case yet still be inspected for airline security. The TSA logo notifies TSA screeners that the latches do not need to be broken for a security check. A cushioned rubber over-molded handle for a comfortable carry with molded-in feet and convenient stacking wells are part of the exterior contours providing added convenience when transports multiple cases.
