  • guardrail posts act as levers when a force is applied along the top rail. The weak link isn't where the bolts hold the post to the rim joist but rather where the rim joist attaches to the joists.

In fact, according to some experts, it's impossible to achieve a code-compliant post-to-joist connection on a wood frame without using special metal& ...
