HBC Post Base


On This Page

This product is only available in Canada

The updated HBC post base is a post-installed saddle for connecting posts to wood in applications such as patio covers, deck trellises and pergolas. It offers the same features as the redesigned RCPS, but in a half-base design.

Key Features

  • Meets the intent of of the National Building Code of Canada 2015 for resisting uplift and lateral movement
  • Hot-dipped galvanization provides additional corrosion protection
  • Chamfered corners create a sleeker-looking product
  • Steel embossments provide added strength
  • Drainage outlets help reduce the possibility of water accumulation that can potentially rot the post


  • 14 gauge


  • HDG


  • Use all specified fasteners; see General Notes
  • Do not install bolts into pilot holes
  • Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations (such as fences or unbraced carports)

  1. Factored resistances have been increased 15% for seismic or wind loading with no further increase allowed; reduce where other loads govern.
  2. Uplift resistances do not apply where bases are nailed into the end grain of post as per CSA O86-14.
  3. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. Values in the table reflect installation into the wide face (see technical bulletin T-C-SCLCLMCAN in Related Literature above).
  4. Factored resistances shown assume dry service condition (KSF = 1.00). Multiply table values by 0.67 under wet service conditions.
  5. Nails: 16d = 0.162" dia. x 3 1/2" long.
