The weight capacity depends on the model of the table that you have. Most models are between 450lbs - 600lbs. The label on your table may say as little as 250lbs. The label weight was determined by testing the table at 4X of the weight on the label per UL standards.
Example: 250lbs (on label) means the model successfully tested at 1000lbs
If you don't know which model table you own, please refer to our website of product models. Each product page has a section for specifications where the weight capacity is listed. You can also email info@hilllabs.com with your serial number and ask what model you have. Once you know the model you own, you can locate the owner's manual which will list the weight capacity.
