Frequently Asked Questions

What everyone's asking.

Who makes Roto Grip Bowling Balls?
Roto Grip products are manufactured at Storm Products, Inc. in Brigham City, UT. Roto Grip was purchased by Storm in 1997 and since then all balls have been made in Utah. Roto Grip designs their own cores and covers to be unique and not similar to Storm balls. Although you should see some similarities in our products because they are made on the same manufacturing lines.
Does Roto Grip have a cleaner for their bowling balls?
As of right now Roto Grip does not produce a cleaner for our products. We do, however, recommend the use of Storm cleaners and polishes on our products. Since they are made in the same facility these products are designed to work best with storm cleaners and polishes.
What is an X-Blem? X-Comp? Pro-Pin? Pro-CG?

X-COMPS

An X-Comp will have an X stamped by the serial number. X-Comps generally have a cosmetic blemish. The Pin distance is in the 2-4” only range and top weight is 2-4 ounce range. The reaction of the ball will be the same as a 1st hand quality ball. The package is marked with a small red number that denotes the specific issue.

X-BLEMS (Seconds)

An X-Blem will have an X stamped by the serial number. X-Blems are seconds due to a cosmetic blemish similar to an X-Comp, but the specifications fall out of the 2-4 / 2-4 range. There are a couple of areas that the ball would not meet some first quality manufacturing specifications (i.e. core chip or a mis-used core). The reaction of the ball will be the same as a 1st hand quality ball. The package is marked with a small red number that denotes the specific issue.

PRO-CG

A Pro-CG is where the CG ends up extremely far left or right of the Pin and MB. If you draw a line from the PIN through the CG and then draw a perpendicular line at the half way point of that line. Go out 2 1/2” and then connect the points to create a diamond shape. If the CG is outside that diamond then it is a PRO-CG. This is a first quality ball and lends itself to several special drill options. Please see the enclosed drilling instructions.

PRO-PIN

A Pro-Pin is where the Pin distance from the CG is 5 ½" – 6 ½” out. Anything more than 6 ½” would be termed an X-Blem. This is a first quality ball and lends itself to several drill options. Please see the enclosed drilling instructions.

WEIGHT CLASS

Heavy (H): 12-15 ounces
Medium (M): 8-11 ounces
Light (L): 0-7 ounces

The layout I want to use places the Pin in/near my finger. What can I do?

If the desired Layout puts the pin too close to your fingers or puts the pin in your finger hole, you may either:

  • Drill the pin out, completely removing the entire pin.
  • Shift the layout slightly to leave at least a 1" buffer from the edge of the pin to the nearest hole.
