Abstract: A system and device for installing and mounting conduit upon a surface such as a roof. The system made up of at least one support block having a base and an upper portion, a support rail and a variety of attachments for holding conduit to the rail. Each of the various blocks in the system configured to nest when oriented in a first direction to stack in an elevated position having a greater height when oriented in a second direction. These pieces are configured to work together to provide a mounting system with significant advantages over other devices that exist in the prior art.
