Abstract: Electronic shelf label (ESL) carriers including an attachment member to be secured to a supporting surface such as a C-channel, a holder member with tabs for removably receiving and supporting the ESLs, and a cover member pivotally carried by the top or the bottom of the holder member to overly and protect the ESLs. The attachment member and the holder member include interengageable complementary adjustment elements to enable the ESLs to be displayed at a zero angle or a positive or negative angular orientation relative to the supporting surface. In one embodiment, the attachment member has a pair of forwardly extending legs each of which include a pair of spaced cavities, with the holder member including upper and lower elements with complementary protrusions which can be selectively engaged in the cavities to adjust the viewing angle.
