Door Frame Pull Up Bar

I want to get down a front and back lever but I don't have anywhere to practice it. Would anyone know what the best kind of bar that goes between a door frame is? I'd google it but you guys seem more trustworthy

Either look at ebay or walmart/sports store for doorframe pullup bar or get one of those Iron Gyms that cost 2x as much but are more robust.

I just bought some random door frame pullup bar... holds fine. Gets the job done.

Same here, no racism or anything but I bought mine in an indian sports store here in Doha and those stores are known for not superb quality but the pullup bar holds just fine
