Appleton CL-300MN Malleable Iron Conduit Clamp 3 Inch

Product Description

The APPLETON CL-300MN is a 1-hole malleable iron conduit clamp designed for securing 3-inch conduit runs to structural surfaces. Malleable iron construction provides the durability and mechanical strength required for industrial and commercial electrical installations. This clamp is a standard hardware component used by licensed electricians and electrical contractors to support rigid metal conduit, intermediate metal conduit, and similar raceway systems at consistent intervals along walls, beams, and ceilings. Its 1-hole design allows for straightforward fastening with a single fastener, keeping installation efficient and the mounting footprint minimal.

This clamp is suited for commercial and industrial electrical work where 3-inch conduit must be supported at code-required intervals. Typical applications include conduit support in mechanical rooms, electrical rooms, warehouses, manufacturing facilities, and utility spaces. Electricians working with larger conduit sizes will find this clamp a practical fit for surface-mounted and structural support installations requiring reliable, code-compliant raceway management.

Key Features

• Malleable iron construction for high mechanical strength and durability in demanding environments
• 1-hole mounting design for fast single-fastener installation
• Sized for 3-inch conduit for precise fit and secure support
• Standard OEM-style form factor compatible with common conduit support layouts

Compatibility

Designed as an OEM-style replacement and standard hardware fitting for 3-inch rigid metal conduit and intermediate metal conduit support applications in commercial and industrial electrical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for conduit support spacing and fastening. De-energize any circuits in the work area before installing or adjusting conduit support hardware. Use appropriate anchors and fasteners rated for the mounting surface material. Avoid over-tightening fasteners, which can crack or distort malleable iron fittings.
