The BC post cap is designed to connect a beam to a post. The 18-gauge material of this post cap makes it ideal for light-duty connections. The BC provides uplift and lateral resistance and includes sizes for both nominal and rough lumber.

Key Features

  • Opposing flanges provide increased lateral resistance
  • Attains full allowable load using either common nail or pneumatic nail sizes
  • Light-gauge material designed for light-duty applications

Material

  • 18 gauge

Finish

  • Galvanized. Some products available in ZMAX® coating. See Corrosion Information.

Installation

  • Use all specified fasteners; see General Notes
  • Do not install bolts into pilot holes
  • Install with 0.162″ x 3 1/2″ nails or 0.162″ x 2 1/2″ nails

BC/BCS 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. 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.
  3. Base allowable loads assume that nails have full penetration into the supporting member. Loads do not apply to end-grain post installations.
  4. 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.
