The DDB Unlimited ST-42DX data cabinet indoor enclosure cream finish is constructed from state-of-the-art AlumiFlex material that is as rigid as steel yet noticeably lighter. The AlumiFlex material allows you to operate communication electronics without affecting or being affected by RF's influences. This indoor aluminum enclosure 42 x 23 x 25 in provides added depth to help in situations that require such. Left or right mountable front and rear doors allow access to both sides of equipment. The doors are recessed with a non-intrusion locking system. The data cabinet is painted with a non-RF's influenced, textured, scratch-resistant powder cream finish. Two screened areas are built-in for ventilation. Air conditioner, heater, and fan kit are optional add-ons. One set of adjustable siding rails with 19 in EIA standard spacing are included so that you can customize the data cabinet to fit your needs. The stackable electronic equipment cabinet features rounded corners for safety. The DDB Unlimited data cabinet enclosure is Class 250, type 2 NEMA rated.
