nVent CADDY 2FMP28 Armor Multi-Purpose Beam Clamp, Spring Steel, 1/4-Inch Rod

nVent CADDY 2FMP28 Armor Multi-Purpose Beam Clamp, Spring Steel

The nVent CADDY 2FMP28 Armor Multi-Purpose Beam Clamp (Caddy®, formerly Erico) is a spring steel clamp built to secure a 1/4-Inch threaded rod directly to structural steel beam flanges ranging from 1/8" to 1/2" thick. Rather than drilling or welding into the beam, installers position the clamp over the flange and tighten it down to create an immediate, load-rated attachment point for hanging conduit, pipe, cable tray, and other overhead support systems. The spring steel Armor construction is engineered to maintain firm clamping tension across the full 1/8" to 1/2" flange range, making the 2FMP28 a versatile choice for electrical and mechanical trades working on structural steel.

Key Features

• Rod Size: Accommodates a 1/4-Inch threaded rod, providing a ready attachment point for hangers, trapezes, and support rods.
• Durable Spring Steel Construction: The Armor spring steel body resists deformation and retains clamping tension under sustained mechanical loads.
• Beam Flange Compatibility: Fits structural steel beam flanges from 1/8" to 1/2" thick, covering a wide range of common beam profiles on a single clamp.
• Multi-Purpose Beam Clamp Design: Suited to general-purpose electrical and mechanical support tasks wherever a rod needs to be anchored to structural steel.
• Tool-Tightened, Weld-Free Attachment: Clamps directly onto the beam flange, eliminating the need to drill, weld, or otherwise penetrate the structural beam.
• Compact, Field-Ready Form: Sized for quick installation in overhead beam locations common to commercial and industrial construction.

Technical Specifications

• Refer to manufacturer documentation for complete technical specifications.
