The ECBRACKET2 ExpressCard 34mm to 54mm Stabilizer Adapter helps prevent side-to-side movement of a 34mm ExpressCard, while the card is connected to a 54mm ExpressCard slot.
The ExpressCard 34/54 stabilizer can be attached to almost any 34mm ExpressCard to provide added stability and security for your card adapter, including flushmount designed cards.
The ExpressCard 34 stabilizer bracket comes in a package of three, so you won't need to swap adapters when using different EC cards.
