Prior to ordering, we would like to get samples of your bolts and locking tab plates to confirm the tool will work properly.  1 or 2 bolts / 6-12 locking plates.

There appears to be some variance with the locking tab plates from country to country.  Samples will help us confirm the proper tool for your application.

Samples should be sent to our facility, along with your contact information in the box.

NOTE: If you are NOT currently using our tools, we request that you provide us with at least 2 bolts and 6 of the locking tab plates (of each size) for use to test prior to shipping the tool.  We have encountered a number of issues with the various locking tab plates where the angle of the tabs car vary widely from one wheel shop to another.  As a result, we would like to test your bolt / plate combinations with the tool before we ship.  Repeat orders will not require bolt or plate samples to be sent.  Samples should be sent to: Custom Products & Services, Inc., 6286 Claude Way E., Inver Grove Heights, MN. 55076.  Attention: Jim Norton.  Thank you.
