  • TypeCable Management & Conduit

  • Corrosion-resistant 304 stainless steel construction
  • Polished Brite finish provides clean appearance
  • Six-inch square base distributes load evenly
  • Quarter-inch thickness adds structural rigidity

Post Base for Strut Channels

The CALBRITE S45800PB00 post base mounts directly onto 1-5/8 in. strut channels. It provides a stable anchor point for conduit runs in commercial and industrial electrical installations. The 304 stainless steel construction resists corrosion in damp or outdoor environments. Electrical contractors and maintenance teams use it to secure vertical or horizontal pipe supports.

Polished 304 Stainless Steel Build

The base measures 6 in. by 6 in. with a 3-3/4 in. depth and 1/4 in. thickness. Its polished Brite finish adds surface protection while maintaining a clean appearance. The unit bolts to existing strut without welding or specialised tools. It frees installers from fabricating custom brackets on site.

Sustained Load Performance

The 304 stainless material retains structural integrity under continuous mechanical stress and thermal cycling. It does not degrade when exposed to moisture, cleaning agents or UV light over long periods. The fixed geometry prevents loosening that can occur with adjustable clamps. Installations remain rigid without periodic re-torquing.

Questions about this item

How long can a 304 stainless post base handle continuous load before the 1/4 in thickness yields?

The 304 stainless post base is 1/4 in thick; sustained loads beyond the steel's yield point will cause permanent deformation, so size the strut and fasteners to stay within the material's elastic range.

Does the polished 304 stainless finish discolour or transfer heat when the strut channel runs warm all day?

Polished 304 stainless resists discolouration and has low thermal emissivity, so the post base stays silver and does not become a noticeable heat source during continuous operation.

What strut channel and fasteners are required to mount this 6 in square post base?

The base fits 1-5/8 in strut channels; you must supply compatible strut nuts, bolts and washers to complete the connection.
