Load Tables

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

    For stainless-steel fasteners, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.

    Many of these products are approved for installation with Strong-Drive® SD Connector screws.

AC/LPCZ/LCE/RTC Post Caps Load Table
  1. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Loads apply only when used in pairs.
  3. LPCZ lateral load is in the direction parallel to the beam.
  4. For minimum nailing quantity and load values, fill all round holes; for maximum nailing quantity and load values, fill all round and trianglular holes.
  5. 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.
  6. LCE4 uplift load for mitered-corner conditions is 985 lb. (DF/SP) or 845 lb. (SPF). Lateral loads do not apply.
  7. 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.
  8. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
AC/LPCZ/LCE/RTC Post Caps Load Table
  1. The allowable download for the mitered RTC44 and LCE4Z connection is limited to the bearing of the mitered beams on the post and shall be determined by the Designer.
  2. The allowable download for the main beam in the square-cut RTC44 connection is limited to the bearing of the beam on the post and shall be determined by the Designer. The side beam allowable download is 1,170 lb.
  3. The combined uplift loads applied to all the beams must not exceed the post allowable uplift load listed in the table.
  4. Connectors must be installed in pairs to achieve listed loads.
