Elma SureLock Expanding PCB Card Retainers

Elma Electronic

The SureLock is a multi-segment, extruded aluminum retaining device that secures printed circuit boards in place when mounted directly to the board and slid into a channel in the cold plate. A simple turn of a screw enables the SureLock to expand and securely hold the card assembly in place. The design facilitates conduction cooling by transferring heat from a circuit card to a cold plate or the extruded side walls of an enclosure. Available in three different expansion sizes: .480", .325", and .290".
