Check the listing for details. Bowflex SERIES 1 SelectTech 552 Dumbbells Replacement Weight Plate #4 (7.7 lb). Condition: Used. Listed at 15.00 USD. This sale is for a Series 1 Bowflex 552 dumbbell replacement weight/plate. This is the #4 weight/plate and has a weight of about 7.7 lbs. The tab is still in tact and works as it should. These look like they were left with some water in the base so a little bit of rust on the bottom. The bottom is also a little beat up. This plate will NOT work with the Bowflex SelectTech 552 series 2. The difference between the two is the series 1 have a gray tab and the series 2 have a red tab. Hey all!
