I have found these really good for expanding your rack - all the Gibraltar add-on tubes etc slot in very easily to allow cross bars to support extra toms etc. Very stable & flexible to give you plenty options. Highly recommended.
These t-legs work great for extending your rack. And it works out cheaper than buying the parts separately. And if you feel you need a longer or shorter t-leg you can just take the attachments off and use a different length of rack tube. It worked for me!!
