Which dumbbells will HYPERBELL work with? 
HYPERBELL works with almost all regular and adjustable dumbbells. From rubber hex dumbbells to Bowflex SelectTech, and everything in between, the foam inside the clamp is designed to adapt and cushion for the perfect fit. However, there are some limitations. The dumbbell handle width needs to be at least 4.5" wide for HYPERBELL to fit. Most dumbbell handles are approximately 6.0" wide. The dumbbell handle also needs to be less than 1.5" at its thickest point. The foam insert inside the HYPERBELL will contour to both straight and curved dumbbell handles. HYPERBELL does not work for PowerBlock dumbbells.

What is the difference between CrossGrips and RYZE-UPS? 
For a chart that shows all the differences, see the Jayflex home page and scroll to the bottom. In short, CrossGrips is made with a stainless steel frame and doubles as push-up handles. RYZE-UPS are adjustable, fit even more doors (wider/taller) and have a rotating handle. 

How strong are CrossGrips?
Unlike other pull-up bars, CrossGrips use the molding on the front and back of the door. This makes them incredibly strong and allows them to hold up to 250 lbs of weight.

Will CrossGrips/RYZE-UPS fit on my door?
CrossGrips and RYZE-UPS are built to adjust and fit on almost any door. RYZE-UPS are adjustable and can fit doors that are taller/wider. To be sure that they will fit on your door, see the diagram on their product page for more details.

Can I take CrossGrips/RYZE-UPS on a plane?
Absolutely. CrossGrips are TSA friendly. Depending on the airport you may have to take them out of your carry-on (just like a laptop) but you will have no issues after that.

Can I return CrossGrips/RYZE-UPS if they don’t fit my door?
Yes, and you will get a full refund. However, since all door frame requirements are given before you order, you will need to pay for the return shipping. Measure your door before you place an order and you won't have any problem.
