Taper Threaded Grip-Twist

Grip-Twist is a swaged splicing and anchorage system that incorporates the use of self-locating taper threaded ends on components for expeditious field assembly. Because parts are swaged to the bars and the threads are formed on the couplers instead of the reinforcing bars, there is no loss of cross sectional area and the full ultimate design strength of the reinforcing system is maintained.

Reinforcing bar sizes No. 3-18 (10-57 mm) can be spliced & anchored by Grip-Twist. Swaging in advance means important time and cost savings for your project. Under fabrication shop conditions, with suitable equipment, just one or two pressings per coupler half are all that is needed to install parts onto most bar sizes. Bars of different sizes may be connected using Transition Grip-Twist.

In the field it is only necessary to rotate one of the two bars until the coupler threads are fully assembled. No specialized equipment or torque wrench is needed for this operation -- only a simple pipe wrench may be needed to overcome bar weight in accordance with assembly instructions. For locations where rebars have a bend or offset and cannot be rotated, Grip-Twist Position Couplers may be used.
