When Should You Specify the Use of No-Hub Fitting Restraints?


Using an engineered fitting restraint adds a higher level of quality and reliability to your build. Even when you've decided to move forward with an engineered solution, it can be challenging to determine which joints should be fitted with a no-hub fitting restraint. Several high-level and detailed considerations must be taken into account to make the correct choice.

Engineers need to be able to make confident, accurate decisions around fitting restraints to ensure the overall quality and safety of the project at hand. That's where HoldRite comes in.

We've been creating high-quality components that help to transform your makeshift methods into reliable, engineered solutions for over 30 years. Along the way, we've become well-versed about the common complications and constraints facing engineers, contractors, and installers.

Our #117 Series no-hub fitting restraints deliver cost and time savings while offering a remedy against separation in high-thrust conditions. Your installers will love the convenience of our restraints, which require no on-site cutting, bending, measuring, or modifications, and you'll love the cost savings.

Overall Project Considerations

Before forging ahead, take a high-level look at the whole project.

First and foremost, engineers, contractors, and installers must be well-versed in the code regulations that apply to your project. Local codes can vary from site to site, and new regulations and requirements are always being added or considered. Moving forward with your project without consulting the code can lead to a disastrous financial hit, dissatisfied clients, and the frustration and hassle of starting over.

Smart project managers will make themselves aware of potential issues involving liability concerns, regulations, and limitations related to the property, and owner concerns. Implications of these issues can impact even the smallest details, including when and where you use no-hub fitting restraints.

Determining Which Joints Need a No-Hub Fitting Restraint

Our no-hub fitting restraint offers many options to address various plumbing construction needs. Still, the reality is, not every joint need a no-hub fitting restraint. Some joints perform adequately with a typical no-hub fitting.

There are a few key factors to consider when making this determination:

  • Pipe size
  • Head pressure considerations
  • The number of stories
  • Seismic applications

An additional consideration is whether field-devised methods have been used to create fitting restraints. This factor, in particular, can impact many decisions and create issues down the line. HoldRite recommends starting your project with a proven, engineered solution that takes the guesswork out of pipe fitting.

Problems with Field-Devised No-Hub Fitting Restraints


Why not continue with the field-devised methods your team has been using?

Field methods may lead to a passing grade for your inspection, but it's impossible to forecast what might happen to this hodgepodge system of joint restraints in the long run. Most importantly, when you employ the use of makeshift fitting restraints created from whatever materials are most accessible, your completed build may not be robust enough to handle harsh hydraulic jump thrust conditions.

Many a builder has run into issues long after a project has been completed due to inadequate, on-the-fly solutions that aren't appropriate for long term use or the high pressure associated with extreme thrust conditions.

No-hub fitting restraints created in the field carry a risk of many potential issues:

  • Code violations - since these fittings are not specified, there's a higher risk of failing your inspection
  • No standardization, often even within the same project, making it challenging to construct a reliable soil pipe system
  • Labor intensive versus engineered components, which can be installed in a fraction of the time
  • The potential liability associated with using untested methods and materials

HoldRite goes above and beyond to craft products that offer outstanding value and real reliability.

Our #117 Series is the ideal solution for restraining hubless cast iron soil pipes against separation during high thrust conditions.

Features include:

  • Improved linkage of no-hub pipe fittings at direction changes as well as straight, inline joints
  • Rain leader system protection against water blow-outs
  • Supporting joints from both longitudinal movement separation and diagonal misalignment
  • Fittings created from stainless steel, black iron, and/or rust-resistant, zinc-galvanized components
  • Easy install with no special tools

Project managers will love the fact that our kits are all-inclusive. They'll be able to calculate the total cost for your fittings from the start. Each kit comes with right-sized fittings, galvanized straps, stainless steel band clamps, and all associated parts needed for specialized components.
