ATAS International introduces a new coping, which incorporates secure locking features to increase its performance in high wind environments.  Rapid-Lok SL Coping is a snap-on system with continuous cleats front and back with no exposed fasteners.  The system includes the coping cover offered in a wide variety of materials, gauges, and colors in 12’-0” lengths; a continuous 22 gauge canted front cleat to provide slope and spring rear cleat to snap-on; guttered internal splices that eliminate the need for caulk or tape at the joints; and all cleat spacing tools and screws required for proper installation. 

Rapid-Lok SL Coping has a 20-year 120 mph windstorm warranty and has been tested per  ES-1 as required by International Building Code for low-slope perimeter edge systems.  Factory fabricated miters, end caps, and other accessories are available for a complete Rapid-Lok SL Coping installation.

This new product joins ATAS’ other three copings: Continuous Cleat Coping, Rapid-Lok Coping, and Rapid-Lok Ultra Coping.

Bob LeClare, Director of Perimeter Edge Metal for ATAS, stated, “Rapid-Lok SL Coping meets the growing demand for a continuously cleated coping system that snaps on without any exposed fasteners or need for time consuming crimping in the field.  Additionally, testing per ANSI/SPRI/FM 4435/ES-1 has shown Rapid-Lok SL Coping can resist very high wind speeds; and the system includes pre-punched cleats, setting tools, and fasteners to assure it is installed to perform as tested.”
