nVent CADDY Spring Steel Threaded Rod Hanger

nVent CADDY 4TIB Spring Steel Threaded Rod Hanger

The nVent CADDY 4TIB is a spring steel threaded rod hanger built for fast, tool-free installation of 1/4" threaded rod to structural steel, angle, purlin, or decking. Instead of pre-threading a nut and washer onto the rod, the 4TIB uses a thread-install spring mechanism that lets the rod be hand-threaded directly into the hanger body. The 4TIB family is offered in three attachment styles — Angle Bracket, Grid Bracket Shot-Fired (GBSF), and Shot-Fired (SF) — so installers can match the hanger to the structural member and attachment method used on the jobsite. Manufactured from durable spring steel, the 4TIB is designed to hold its shape and clamping tension through repeated installations for electrical, mechanical, and general structural rod-hanging work.

Key Features

• Trade Size: Sized to accept 1/4" threaded rod, matching one of the most common support-rod sizes used in electrical and mechanical trade work.
• Spring Steel Construction: The hanger body is formed from spring steel, giving it the flex needed to grip threaded rod securely while resisting permanent deformation over repeated use.
• Attachment Type Options: Available as Angle Bracket, Grid Bracket Shot-Fired (GBSF), or Shot-Fired (SF) versions, letting installers match the 4TIB to structural angle, a grid bracket, or a direct shot-fired pin attachment method.
• Thread-Install Function: The spring-steel jaws engage the threads of the rod as it is inserted, allowing the rod to be installed by hand-threading rather than requiring a top nut, washer, or pre-threaded rod end.
• Tool-Free Speed: Because the rod threads directly into the spring steel body, installers can hang support rod runs faster than with conventional nut-and-washer style rod hangers.
• Compact, Low-Profile Design: The attachment point stays close to the structural member, helping keep suspended rod runs neat and reducing offset from the mounting surface.
• Reusable Holding Action: The spring steel thread engagement is designed to hold the rod securely in place once installed, supporting stable, long-term suspended runs.

Why nVent CADDY?

nVent CADDY builds fastening and support hardware relied on by electrical and mechanical contractors for dependable, fast field installation. Across its Angle Bracket, Grid Bracket Shot-Fired (GBSF), and Shot-Fired (SF) versions, the 4TIB carries forward the same spring steel body and thread-install holding action, giving contractors flexibility in attachment method without sacrificing a secure, repeatable hold. For crews hanging 1/4" threaded rod from structural steel, purlin, or grid bracket, the 4TIB family offers a straightforward way to speed up support installation on the jobsite.
