Our window frames are identical to your preferred dome frames' downward triangles but slightly wider to cover the triangle for water-tightness. The simple design and the hinges allow you to add heat-activated auto openers.

Tunnel modules are not available for small-sized domes. Modules are designed and sized to connect 2V, 3V, 4V domes. (2V to 2V, 2V to 3V, 3V to 3V, 2V to 4V, 3V to 4V, 4V to 4V)
Door frames can also be integrated into the tunnel exits.

These passive vents will protect your triangular ventilation on the panel from rain and dust if you install either steel or a nylon mesh to the cut-out gap.
