Customer Testimonial

"GripSafe plugs have been valuable assets on the LNGC site. The quick and easy installation, use, and removal of the plugs have made testing plain end pipe simple. The Lifting Device makes rigging of the larger plugs into position fast, convenient, and safe. The design of the grippers leave little to no marks inside the pipe. Torque values and plug info on the front plate makes plug identification and double-checking for the right plug usage easy. Overall, the GripSafe plugs are an excellent product."
