go to children's department. They have a partition for a child safety purpose. I am not sure what its call. Its a gate type, where u can open the door...
Hi, I got mine in carrefour too. they also have it in giant or tesco. in the baby/children department. call children door barrier. it is quite good, no need installation one. just turn the nob and fix it in between the walls/door frame. can also extend anytime u like. i bought at rm 99 (last year lar...) now i think 100+
