The Ray-Ban RB1972 Octagon runs an all-metal build, front and arms alike, with 140mm temples shaped to meet the octagon's angled edges. This aftermarket pair follows that same profile, so the arm meets the front at the correct angle instead of the smoother curve used on round or oval Ray-Ban styles. The 1972 line also comes as the RX1972V prescription frame, which shares the same octagon shape, so confirming the RB sunglasses code here avoids ordering the eyeglass version by mistake.

An eight-sided front like the 1972's puts the hinge at a sharper angle than a round or square frame does, so the screw connection has to hold more directional stress. If one arm sits a little proud of the frame compared to the other, it's worth checking hinge tension before assuming the arm itself is bent. Octagonal shapes are less common than round or square fronts, so it's worth ordering by the exact code rather than a general shape description.
