With the SeaLATCH USB PCI bracket, you can use open USB headers on the motherboard to easily add a locking USB Type A connector to your computer enclosure. The USB PCI adapter interfaces to a variety of small board computers and motherboards via an internal USB header connection. Order the correct cable for your motherboard under the Accessories tab.

The SL-PCI integrates Sealevel’s SeaLATCH locking USB port, which is fully compatible with standard USB cables. When used with a USB cable with a SeaLATCH USB type A connector, the metal thumbscrew provides a secure metal-to-metal connection and prevents accidental cable disconnection. Order optional USB cables with SeaLATCH locking USB connectors under the Accessories tab.

The SL-PCI is compatible with any computer with an available PCI location and provides a clean, professional installation. The SL-PCI does not require or use a PCI slot on the system board. If you need two SeaLATCH locking USB ports on a PCI bracket, order the SL-PCI2. If you need a low-profile PCI bracket, order the SL-LPCI.

A 2mm 4-pin Molex header is integrated into the adapter and provides the internal USB interface to your host system. Simply choose the correct internal USB cable for your application. For EBX and larger motherboards with a 0.1 onboard USB header, order the CA260 internal USB cable. For smaller motherboards with a 2mm onboard USB header, order the CA383 internal USB cable.
