Description & Specs

The Simpson Strong-Tie CPT90Z concealed post base anchors a 90mm to 100mm square timber post to concrete while hiding the steelwork inside the post - no visible stirrup at the base.

  • Suits: 90-100mm square posts
  • Material: 2.7mm carbon steel
  • Finish: Zmax galvanised
  • Leg length / stirrup width: 90mm
  • Bolt hole: 12mm, bolt-down blade stirrup

Use it for pergolas, verandah posts and deck posts where a clean post-to-slab look matters. The blade slots into a kerf cut in the post and pins through, while the bolt-down base fixes to the slab. Zmax galvanising suits exterior exposure.
