The Falcon Eyes CB-140 1.40m Paper Background Counterweight can easily be attached to the bottom of your paper background. This counterweight ensures that your background doesn’t curl and causes the paper to hang straight down. The CB-140 contains 2 bars, one of which is equipped with an eyelet allowing you to attach the bar to something. Further, this eyelet provides you with the option to use the counterweights for posters for example.
