Adjustable Dumbbell On-the-Knee End Caps

We created these caps to allow you to comfortably perform on-your-knees exercises with adjustable dumbbells.
Using these will prevent you from experiencing pain from the shaft.

This listing is for a set of 2 caps. (Dumbbells are not included.)

We have sold over 180 sets to date.

If the product breaks within 2 weeks of purchase while following the usage precautions,
we will replace it free of charge.

The size is slightly smaller than a 1.25kg plate to prevent breakage.

I personally use IROTEC screw-type dumbbells,
but I believe these will work with any 28mm screw-type dumbbell.
I was able to use 3-4 plates, including the collars.
*The screw part needs to be exposed by about 1.5cm for attachment.

Each cap weighs approximately 70g.

The material used is durable ABS.
I have been using them for about half a year since creation without any breakage.
(With weights around 25kg, used every other day)

Please understand that these are handmade items and may have small burrs, dents, or scratches.

☆Usage Precautions

- Although the photo shows the dumbbell standing upright,
please refrain from doing so as it may cause injury or breakage.
- Do not overtighten the caps unnecessarily, as this can cause breakage.
- Do not drop the dumbbells, as this can lead to breakage.
- Do not use the caps themselves as collars, as this is dangerous.
- Avoid direct sunlight, as it will accelerate material degradation.
