The Most Efficient Geocell Connection Device

The most productive way to connect GEOWEB sections, and assure the longest performance is with ATRA® Keys. The ATRA Keys provide a more secure and permanent load-transfer connection—and the polymeric material won’t corrode, even when exposed to corrosive environments. ATRA Keys are easy to install with just one worker, and assure a positive connection with one easy turn.
