Ball Python weight

How much are most ball pythons but I'm going to get a rack system for ball pythons up to 2,000 grams and I've been wondering if that would be good for an adult.

Some REALLY big females can get 6 feet and upwards of 5000 grams. 2500 to 3000g is probably a more likely adult female ball range

It can really vary, my male is almost 2500 grams. He's the biggest and oldest snake I have right now, but he rarely refuses a meal.

What size are the tubs in the rack?

The tubs are 22" L x 16" W x 5 1/2" H.
