It sounds like you're looking for a PVC rack for outdoor use, specifically designed to house a PDU (Power Distribution Unit) and support a 16-channel DVR (Digital Video Recorder) system, which is typically used for surveillance purposes.

Here’s a breakdown of what you might be looking for:

1. PVC Rack for Outdoor Use:

   • A PVC rack is typically lightweight, durable, and resistant to environmental elements like rain, UV rays, and temperature changes. It’s a great choice for housing electronic components outdoors.
   • The rack needs to be weather-resistant and sturdy enough to hold the PDU and DVR.

2. PDU (Power Distribution Unit):

   • A PDU is used to distribute power to multiple devices, making it essential for equipment like DVRs, cameras, and other connected devices.
   • You’ll likely want a Jumbo PDU, which could refer to a unit with multiple outlets to power all the connected devices.
