The 7DTB-C has an oval opening in the center top side opposite the brackets, and a drain hole on the floor. This allows the operator full access to the spectrum analyzer controls.
The 3TB is designed to be hung on the inside of the bucket. The stand off bracket has been removed, thus allowing inside mount. For an outside mount, please order 1TB.
PTI's NEW Double Tool Tray (2TB) is designed to hold most CATV monitors.
