Metal Building Roof Hatch
R&S Metal Building Roof Hatch for safe roof access via interior fixed ladder. The integral metal building curb flashes to any Standing Seam, R-Panel or Insulated Metal Panel roof system. As a result, there is no need for a separate curb or flashing. Common sizes are 2′-6″ x 3′ and 3′ x 3′.
Our roof hatches are 0.125″ aluminum for ultimate durability. Curbs include 1″ (R6.5) insulation with higher R-Values also available. The perimeter rubber gasket insures long-term protection against leaks. Gas springs with dampers deliver smooth and controlled lift assistance. Hold open arm with vinyl grip locks lid in open position. All Metal Building Roof Hatches include interior and exterior padlocks with concealed hardware for complete security. Several options are available; for example: steel construction, custom color finish, custom size, integral OSHA-compliant safety rail and safety post (ladder-up). Lastly, replacement parts are readily available and easy to install.
