Nursery Supplies' Grip-Lip containers are designed for strength and durability. You can pick them up with forklifts without damaging the container. If you handle large containers in your operation, you need the Grip-Lip container. These containers have a heavy-duty rolled rim for handling ease and strength. Grip-Lip and Econo-Grip containers have replaced Polytainer cans in our nursery container inventory. The Grip-Lip combines the heavy duty aspect of the polytainer line with the less expense of the blow-molded classic line.
