DynaRound Hatch Guards

Non-penetrating, affordable solution to protect rooftop entry/exit points

The DynaRound Hatch Guard provides a non-penetrating, affordable solution for life-saving protection at rootop entry/exit points.  The adjustable, self-closing gate prevents accidental entrance.  It is easy to install, mounting directly to the roof hatch with a unique compression fit design and including snap-in rails; there is no need for drilling, which maintains the waterproofing integrity of the roof.  Multiple sizes are available to fit almost any hatch.  DynaRound Hatch Guards can be used for both temporary and permanent solutions.  They meet numerous safety requirements, including those established by OSHA, IBC 2015 and the National Building Code of Canada.

DynaRound Hatch Guards are constructed with yellow or gray fiberglass reinforced plastic (FRP) posts and guardrails, with galvanized fittings.  FRP is corrosion resistant even in the harshest enviornments, chemical resistant, electrically and thermally non-conductive, and easy to maintain.  UV inhibitors and a synthetic surfacing veil provide optimum protection from the effects of UV weathering.
