The ABB CB3/4-G is a PVC-coated clamp back fitting designed to support and secure conduit runs in corrosive or wet environments. The clamp back style holds conduit against a surface — wall, ceiling, or structural member — providing a fixed anchor point that resists vibration and movement. The PVC coating adds a protective barrier over the base metal, making this fitting suitable for installations where moisture, chemicals, or outdoor exposure would degrade an uncoated fitting. Licensed electricians and industrial maintenance technicians are the primary installers of this type of hardware.
Clamp back fittings like the CB3/4-G are commonly used in industrial plants, wastewater facilities, marine environments, food processing areas, and other locations where corrosion resistance is required by code or specification. The 3/4-inch trade size matches standard 3/4-inch conduit. This fitting is appropriate for both surface-mounted and exposed conduit systems where a secure, corrosion-resistant anchor is needed along the conduit run.
Designed as an OEM-style fitting for use with 3/4-inch trade size conduit systems requiring PVC-coated corrosion-resistant support hardware.
Installation is performed by a licensed electrician in accordance with applicable NEC requirements for conduit support and spacing. Power down the circuit before working on any conduit system carrying energized conductors. Use fasteners compatible with the mounting surface and appropriate for the environmental conditions of the installation. Do not damage the PVC coating during installation, as breaks in the coating can allow corrosion to develop at the exposed metal.
