The DSP shopping cart seat belt buckle incorporates all of the distinctive features of our most widely distributed CRB® model and adds two more important features. The DSP’s buckle provides an additional level of safety by adding a third catch point that is activated by depressing a button while squeezing the side arms, and has a latch override. These subtle yet significant differences build upon all of the other well-designed and engineered features of our CRB® buckle.
