18 in Spring Steel Conduit Hanger

The Caddy 812MB18A is a spring steel box and conduit hanger with an 18 inch overall length. It supports EMT conduit in 1/2 in and 3/4 in trade sizes. The hanger mounts to a 4 in square box using a threaded rod with a .25 in mounting hole. It is CEC and NEC compliant and carries cULus listing.

Installing the Hanger on Threaded Rod

The hanger attaches via a screw mount to a threaded rod through the .25 in hole. Spring steel construction allows the clip to grip the conduit without separate fasteners. Misalignment of the rod or using conduit outside the 1/2 in and 3/4 in range will prevent a secure fit. The corrosion resistant coating helps maintain grip in damp locations.

Limits of Threaded Rod Mounting

The .25 in mounting hole diameter restricts the hanger to compatible threaded rod sizes only. It is designed specifically for 4 in square boxes and the two listed EMT trade sizes. Installations requiring larger conduit, different box types, or alternative mounting methods cannot use this hanger. The 18 in length is fixed and cannot be adjusted.

Questions about this item

How do I verify the 812MB18A hanger is holding the 1/2 in and 3/4 in EMT conduit securely after installation?

Confirm the spring steel clip grips the conduit firmly and the 0.25 in mounting hole aligns with the threaded rod; the corrosion-resistant coating should show no deformation under load.

What comes in the box with the 812MB18A and what must I purchase separately for a 4 in square box installation?

The box includes the 18 in spring steel hanger only; you must supply the threaded rod, screws for the 0.25 in mounting hole, and the 4 in square box itself.

Which version of the 812MB18A should I choose for 1/2 in versus 3/4 in EMT conduit on a threaded rod?

The single 812MB18A model fits both 1/2 in and 3/4 in EMT trade sizes, so one version covers either conduit diameter on a threaded rod mount.
