Each charging slot features a tension lock that ensures secure charging connectivity, and each slot can be used to store ID cards or other items that are exchanged for and returned when the receiver is not in use. Each Charging Tray comes with a power supply.

The LA-381 charging tray can be mounted in a variety of ways to accommodate your venue’s needs, including wall, drawer, rack, or tabletop installation. An optional cable management system can also be ordered and incorporated to keep the charging tray and receivers neatly organized.
