L.H. DOTTIE TW400 One Hole Strap

This steel strap secures 4 inch EMT conduit or pipe to mounting surfaces. It is designed for electrical installations where rigid conduit runs require a single-point fastening method. The component suits commercial and residential wiring projects.

Check conduit size and surface material

Verify that the conduit outer diameter matches the 4 inch nominal size before ordering. Confirm the mounting surface can accept the fastener type required for the single hole. Ensure the zinc-plated finish meets the environmental conditions of the installation site.

Steel construction with zinc plating

The steel body provides mechanical strength for heavy conduit runs. Zinc plating adds corrosion resistance for indoor or sheltered outdoor use. The single hole design simplifies alignment and reduces hardware count during installation.

Questions about this item

Does the DOTTIE TW400 one-hole strap include mounting screws or must they be purchased separately?

The strap is supplied as a single steel piece; fasteners are not included and must be sourced separately.

Is the 4 in size the only version available for the TW400 model?

The TW400 designation corresponds to the 4 in trade size; other diameters carry different model numbers.

Will the zinc-plated steel strap hold a 4 in EMT conduit securely on a vibration-prone surface?

The one-hole design clamps the conduit against the mounting surface; zinc plating resists corrosion in damp or outdoor locations.
