nVent CADDY 4H58/M58S Spring Steel Hammer-On Beam Clamp

nVent CADDY 4H58/M58S Spring Steel Hammer-On Beam Clamp

The nVent CADDY 4H58/M58S Hammer-On Beam Clamp is a spring steel flange clip engineered to attach threaded rod hangers directly to structural steel beams without drilling, welding, or bolt-on hardware. This beam clamp is offered under two designations — the current nVent CADDY model M58S and the equivalent legacy Erico Caddy model 4H58 — and fits beam flange thicknesses from 5/16" to 1/2" while accepting a 1/4-20 threaded rod, giving electrical, mechanical, and HVAC contractors a fast, code-friendly way to support conduit, cable tray, pipe, and other overhead loads directly from structural steel framing. The spring steel body grips the beam flange securely once hammered into place, holding the load in tension against the underside of the flange for a stable, vibration-resistant connection point.

Key Features

• Flange Fit: Fits beam flange thicknesses from 5/16" to 1/2", covering a wide range of standard structural steel beam profiles found on commercial and industrial jobsites.
• Rod Size: Accepts a 1/4-20 threaded rod, allowing quick, secure connection to standard hanger rod assemblies without additional adapters.
• Durable Spring Steel Construction: Manufactured from spring steel for dependable holding strength and consistent load-holding tension over the life of the installation.
• Hammer-On Installation: Clips directly onto the beam flange with a hammer, eliminating the need for drilling, welding, or bolted clamp assemblies and speeding up overhead support work.
• Beam Clamp Design: Functions as a hammer-on flange clamp for suspending threaded rod support systems from structural steel beams, a common alternative to welded or drilled attachment methods.
• Field-Ready Hardware: Compact, single-piece design is easy for electricians and mechanical contractors to carry, position, and install on structural steel without special tools.
• Model Options: Offered as nVent CADDY model M58S and the equivalent legacy Erico Caddy model 4H58, both representing the same spring steel hammer-on beam clamp design so crews can order under whichever part number matches their spec.
