Abstract: A construction assembly for attaching thin panels to a support frame. An elongate base strip suitable for attachment to a support frame. Two walls extending from the bases strip define a slot, one of the walls having plural teeth. A mating cover strip has a flexible projecting wall with plural teeth on one side facing the teeth of the slot but fewer in number. The cover strip and elongate base have thin panel support walls facing each other. The flexible projecting wall bends on a fulcrum attached to one of the second wall and the flexible projecting wall, such that upon insertion of the flexible projecting wall into the slot, the teeth are urged towards each other to grip a panel in the slot.

Abstract: A framing system suitable for the assembly of thin panels such as glass or acrylic, which might be used in the construction of greenhouses, sun rooms, pool enclosures, wind screens or other non-insulating applications. The framing system consists of a unique three piece design which makes it particularly suitable for application to plastic materials such as ABS or PVC. The three piece design consists of an main supporting beam with a toothed slot to accept a correspondingly toothed extension of a T-shaped cover strip. The cover strip acts only to retain the supported panel against the beam. The beam supports the entire weight of the panelling. The beam is grooved along its edge in order to mate with a correspondingly shaped connector block. The connector block serves to connect adjacent beams.
