The R-Stack is an innovative design that combines a Deadbreak Connecting Plug with a Deadbreak Elbow. Our premolded composite is factory tested, with a greatly reduced installation force and stack height.

The result: an easier, more reliable, and cheaper option than traditionally stacked elbows.

• More reliable — The R-Stack interface combines two units into one, eliminating the need for a connecting plug! This combination design reduces the risk of complications during assembly in the field, such as cross threading. And, each product is individually tested prior to shipment.
• Easier to install — Total assembly force is only 25 lbs., as opposed to the 100 lb. force required to install a standard connecting plug. Also, the traditional spanner and torque wrenches are no longer needed for the installation. All that’s required is a single installation tool (included with each kit).
• Smaller stack height — Using the R-Stack reduces the stack height 4” for every two elbows (a 20% reduction). Its reduced height makes the R-stack invaluable in small cabinets and manholes.
• Less expensive — Molding one part instead of two (elbow and connecting plug) reduces the cost. Plus, the R-Stack can be installed faster and is more reliable, which saves even more time and money!
