Abstract: A frame system for securing a glazing unit to a window portal includes an elongated primary mount extrusion, an elongated mount stop extrusion, an elongated first gasket, an elongated second gasket and a structural sealant. The primary mount extrusion is secured to the window portal. A mount stop extrusion engages the primary mount extrusion with a pair of ratcheting members. The first gasket and the second gasket define a passage therebetween and the passage has a width so that the glazing unit fits therein. A structural sealant is disposed so as to affix the glazing unit to an inner upper surface of the primary mount extrusion.
