PCZ Post Cap


On This Page

The PCZ is designed as a fast and easy post-to-beam connection. With the post and beam flanges in line with each other, this post cap can accommodate several post sizes. The PCZ features a ZMAX® finish to meet exposure conditions in many environments.

Key Features

  • ZMAX finish is standard
  • Easy install with 10d (0.148" x 3") common nails or Strong-Drive® SD Connector screws
  • In-line flanges accommodate multiple beam sizes


  • 16 gauge


  • ZMAX coating; see Corrosion Information


  • Use all specified fasteners; see General Notes
  • Center PCZ legs on post
  • Do not install bolts into pilot holes

  1. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Uplift loads do not apply to spliced conditions. Spliced conditions must be detailed by the designer to transfer tension loads between spliced members by means other than the post cap.
  3. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers known as the narrow face. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for load reductions resulting from narrow-face installations.
  4. Post and beam may consist of multiple members provided they are connected independently of the post cap fasteners.
  5. 0.148" x 2 1/2" nails may be used with no load reduction for uplift and 0.85 of the table loads for lateral.
  6. #9 x 1 1/2" Strong-Drive® SD Connector screws may be substituted for table fasteners with no load reduction.
  7. To order models available for rough size lumber, specify RZ suffix — e.g., PC4RZ.
  8. Fasteners: Nail dimensions in the table are diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
