The RWC QS-50-P is a water heater seismic restraint strap designed to secure tank-style water heaters in place during seismic events. Constructed from polybutylene material, this restraint system helps prevent tip-over and displacement of water heaters up to 80 gallons. It is installed by licensed plumbers in residential and light commercial settings where local code requires seismic bracing for water heating equipment. The QS-50-P is part of the Holdrite Quick STRAP product line, engineered to meet the demand for compliant, efficient seismic restraint installation.
This restraint is appropriate for tank-style water heaters in seismic zones where local plumbing or building codes mandate approved anchoring systems. It is commonly installed in garages, utility rooms, and mechanical spaces in both new construction and retrofit applications. The polybutylene construction resists corrosion, making it a practical choice in environments subject to moisture. Plumbers and mechanical contractors installing water heaters in California and other seismic-active regions will find this strap meets the practical needs of code-compliant installs.
Designed as a seismic restraint replacement or new-installation strap for tank-style water heaters up to 80 gallons.
Installation should be performed by a licensed plumber in accordance with local plumbing and building codes, including applicable seismic bracing requirements. Shut off the water heater and allow it to cool before beginning any work in the immediate area. Secure the strap to approved structural blocking or framing as required by the authority having jurisdiction. Do not use this strap as a substitute for proper structural wall anchoring where code requires it.
