Dip belts can hold anywhere from up to 200lbs to up to 1000 lbs. Some like the one shown in the right is rated at up to 29,400lbs! Considering the World record for 1 repetition of a pull-up is around 250lbs you can see that the 1000 lbs limit is overkill. Most people will not even need 200lbs for their workouts.
