TYPE - ATLA A liquidtight flexible steel conduit designed specifically for extreme hot or cold environments. The flexible inner core is identical to that found in Type LA. The specially formulated PVC jacket remains flexible at low temperatures and resists aging at elevated temperatures. It is listed by Underwriters Laboratories Inc. and certified by Canadian Standards Association
CONSTRUCTION: ATLA has a flexible inner core made from a spiral wound strip of heavy gauge, hot-dipped galvanized steel. The 3/8 through 1-1/4 inch trade sizes contain an integral bonding strip of copper. The 1-1/2 inch and larger are designed with a fully interlocked strip.
The jacketing material is a rugged flame retardant flexible PVC resistant to weathering, UV, oils and many chemicals. See the Chemical Resistance Guide for further details.
APPLICATION: Designed to be used with high temperature machine tool wiring. Ideal for outdoor installations in cold climates.
