Questions & Answers about Hvataljke su pored rešetke.
Su is the 3rd person plural present form of biti (to be).

- on/ona/ono je = he/she/it is
- mi smo = we are
- vi ste = you are
- oni/one/ona su = they are
In this sentence, hvataljke is plural, so Serbian uses su:
Hvataljke su ... = The clamps/tongs are ...
