The Guardian Fall Protection guardrail standard gusset mount is simple to install with either screws or nails, and allows for guardrail systems to be installed flush with outside walls. Guardrail posts used in combination with this gusset are compatible with both 2 x 4 in boards and snap-on metal railings. The Guardrail standard gusset mount may be used in multiple installation locations if undamaged, although new fasteners must always be used with each new installation application.
