The three pictures above illustrate the potential damage that may occur to a dumbbell that has had a significant drop. If the
customer determines that a certain weight plate is not being selection at a weight setting where it should be selected, they
should examine the individual selection collars for any damage similar to these images. This is an indication of a large
impact and such damage is most likely to occur on the 2.5 or 5 lbs plates. It is critical that a dumbbell handle with such
damage be removed from service and replaced. Generally such damage is will be the result of a drop in excess of those
covered by the warranty.
If the Serial Number for a damaged handle starts with 3023B it is possible that the damage occurred from a drop within the
12 inch height restriction of the warranty. This first production lot used Nylon 6 material which was later changed to Nylon
66 result in superior resistance to such damage. In the case of a 30323B serial number a more forgiving interpretation of
the warranty limitations is suggested.
If a customer calls about a dropped handle but nothing seems damaged, they should set the dumbbell to 5 lbs, remove the
handle from the base and very carefully apply some pressure to all the selection collars while looking for any damage as
illustrated in the images above. It is important to apply some pressure to each selection collar parallel to the dumbbell
handle (back and forth) to confirm if there are any cracks in the material that are not obvious. This should be done at
several locations around each collar. An inspection of each weight plate should also be performed and is covered later. It
there is any question about the integrity of the collars, the dumbbell should be replaced.
The weight plate images above illustrate the type of damage one might see after a dropped dumbbell. Obviously the
surface upon which the dumbbell is dropped will greatly affect the damage the weight plates incur. In a very severe drop
one might see damage to the selection tongue as illustrated in the first image. This is clearly from a very significant and
likely repeated drop. This plate must be replaced. In the second image you can see some deformation of the plastic and
also the stressed material (white color). This plate may only have cosmetic damage and be totally usable. As long as the
cover is not split and the plate fits in the base without any added resistance it is probably in good working order despite the
damage. The last image shows deformation from a drop as well as a split in the ultra sonic welded plastic. This plate may
still function but the split weld will allow moisture to reach the core and could start rusting. It is strongly recommended that
this plate be replaced.
