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 for “Heavy-Duty” applications.

Construction:

Inner Core:

• Hot Dipped Galvanized Steel
• 1/2” – 1-1/4” Squarelock Profile with continuous bonding strip
• 1-1/2” – 4” Fully Interlocked Profile

Liquidtight Jacket:

• Flexible PVC
• Resistant to Oils and Mild Acids
• Flame Retardant
• Sunlight Resistant (UV)
• Marked HD for “Heavy-Duty”
