The below environmental considerations should be observed to insure that restraints are and remain in optimal working condition.
- Store in a cool, dry, & dark place to prevent degradation and loss of strength due to exposure to ultra-violet rays.
- Observe the working temperature range of -40°F to 194°F when using these restraints.

Power restraints are designed for use on oil and gas locations. By following the below steps, you can extend the lifespan of these restraints.
- Sunlight will reduce the strength of restraints over time. When not in use store in a dry place outside of the sunlight to avoid fading/sun bleaching of the jacket.
- Keep the restraint free of debris and as clean as possible.
- Keep the restraint from experiencing any physical or chemical damage.
- Maintain the integrity and legibility of the tag.
- All “PR” restraints come with an inspection calendar tag attached, when performing visual inspections punch

Kennedy Wire Rope & Sling provides documented inspections of power restraint assemblies, “PR”.
Due to lack of industry standards regarding this product we will only recertify restraints fabricated by KWRS.
- These restraining assemblies are designed to reduce, but not eliminate the possibility of personal injury, death or damage to equipment. Keep all personnel away from the flow line while under pressure.
- Do not use these restraints for lifting as they are designed for restraint purposes only.
If a restraint has been involved in a load event (i.e. an actual stress event placed on the hose restraint) it is to be removed from service and destroyed immediately.
When installing restraints, any and all requirements and installation practices of the installation company shall be observed. KWRS fabricates restraints for restraining temporary pipework, but it is the installers responsibility to design and implement a proven installation method. KWRS does not install, nor do we provide any recommended installation methods. KWRS fabricates a component to be used as part of a larger system.
