One-Hole Strap for 1/2 in EMT

The L.H. Dottie TW301 is a zinc-plated steel strap designed to secure 1/2 inch EMT conduit to mounting surfaces. It provides a single-point fastening solution for electrical installations in commercial and residential environments. The steel construction offers mechanical strength for rigid conduit support.

For electricians running EMT conduit

This strap suits professionals installing electrical metallic tubing who need a code-compliant fastening method. It is not intended for flexible conduit, cable trays, or non-metallic raceway systems. Buyers requiring multi-hole straps or stainless steel hardware for corrosive environments should consider alternative products.

Zinc-plated steel construction

The steel body with zinc plating delivers corrosion resistance for indoor and protected outdoor applications. This material combination supports the conduit weight while resisting rust in standard atmospheric conditions. The finish ensures longevity in typical electrical enclosure environments.

Questions about this item

What size EMT conduit does the TW301 strap secure?

The TW301 one-hole strap is made for 1/2 in EMT conduit, holding it flat against the mounting surface.

Can I reuse the same mounting screws when replacing an older strap with this steel one?

Yes, the single-hole design fits the same fastener pattern used by standard one-hole straps, so existing screws work.

How do I confirm the zinc-plated finish is intact after installation?

Check that the steel surface shows a uniform silver-grey coating with no bare metal or red rust at the hole or edges.
