PBC Post Beam Corner Connectors
The PBC series is a one-piece connector designed to secure two
mitered beams on a corner post while providing uplift capacity.
Materials: 18 gauge
Finish: G-185 galvanizing
Codes: See page 11 for Code Reference Chart
Installation:
• Use all specied fasteners. See Product Notes, page 17.
• Install PBC on outside corner of post forming tabs to inner side of post.
• Assumes beam members are bevel cut at corner.
The CPB is made of corrosion resistant composite material compatible
with preservative treated lumber. Provides code required 1" stand-off
and can be used with rough lumber sizes.
Materials: High Strength composite
Codes: See page 11 for Code Reference Chart.
IRC R317.1.4, IBC 2304.11.2.7, IRC R407.3, IBC 2304.9.7
Installation:
• Attach base to post with (4) 10d HDG nails.
• Attach post to concrete using 1/2" diameter rod into concrete
and extend into wood member.
• Not recommended for fence posts or other unrestrained (not
xed or fastened at top) applications. These anchors are not
designed to resist overturning (moment) loads.
