i am not sure if i can explain it the right way but here it goes. i have four pieces of pvc pipe ( i use a round three or four inch pipe ) about 6 inches long that is the length that i need to bring my table up to the length that i need to cut my fabric on. i have end caps put on one end of each pvc pipe. i glued my on so that they stay in place. now the pvc pipe is about 7 inches long. i put each pipe on one end of the leg of the table. and it will bring the table up 7 inches. that is a good cutting height that i need. if your shorter than i am at 5 foot 7 you can make you legs longer or shorter. what ever you need. it works great on the normal table legs on a standard table that is 6 to 8 foot long. i hope that this helps. sorry no pic. blessings ogama
