Where can I buy cable glands in Indore?

I want to buy cable glands (https://amzn.in/d/18WWGnt) in Indore. Not buying from amazon because of delivery time. Does someone know the exact shop where i can get this. I am only able to find manufactures and bulk dealers on JustDial. I think that the best place to start would be Choti Gwaltoli or Siyaganj but it would be really helpful if someone can point me to a shop.
