Rwc QB-50-F Water Heater Seismic Restraint Kit 80 Gal

Product Description

The RWC QB-50-F is a water heater seismic restraint kit designed to secure water heaters in place during seismic events. Part of the Holdrite Quick Belt product line, this kit uses a strap-and-bracket system to anchor the water heater to a wall, reducing the risk of tipping, displacement, or connection damage during an earthquake. It is compatible with water heaters up to 80 gallons in capacity. Plumbers and mechanical contractors install this hardware as part of code-compliant water heater installations in seismic zones.

This restraint kit is suited for residential and light commercial applications where local or state building codes require seismic bracing of water heating equipment. It is commonly installed in garages, utility rooms, and mechanical spaces on new construction and retrofit jobs. Jurisdictions in seismic zones — including much of California and the Pacific Northwest — typically mandate this type of restraint for both tank-style gas and electric water heaters.

Key Features

• Designed for water heaters up to 80 gallons capacity
• Provides seismic restraint to reduce tipping and displacement risk
• Wall-anchor design suitable for residential and light commercial installs
• Meets requirements for seismic restraint installations in applicable jurisdictions

Compatibility

Designed as an OEM-style seismic restraint solution for tank-style water heaters up to 80 gallons, including both gas and electric residential and light commercial units.

Installation Notes

Installation is performed by a licensed plumber or mechanical contractor. Shut off the water supply and power or gas to the water heater before beginning any work on or around the unit. The restraint straps must be anchored to structural wall framing — not drywall alone — in accordance with local building codes and seismic bracing requirements, which may reference IPC or local amendments. Do not over-tighten straps against the water heater tank in a way that could deform the jacket or damage fittings.
