I can’t be totally sure what rope piece it is, but if I had to guess it would be from the new Construction Zone kit. The colors certainly fit Caution Tape’s aesthetic.
I can’t tell if its two 228-2500-440 (36x pitch rope) or one looped 228-2500-448 (120x pitch rope).
I personally hope it’s one long 120x pitch rope snaked between the arm and the lower claw, that would be rad.
