EQ Mount Counterweight Adapter for Dumbbell Plates

The adapter was designed for plates with the following dimensions: Inner diameter: 31 mm Plate thickness: 34 mm Mount counterweight shaft diameter: 12 mm The main version is designed for one plate (tested with a 1.25 kg plate). An additional back part is included so the holder can also support two plates if more counterweight is required. This provides a flexible and inexpensive alternative to the original EQ2 counterweight. Clamping screw The holder uses the original EQ2 M8 locking screw. Recommended screw specifications: M8 screw Length: 40 mm or longer Smooth section: ~12 mm Threaded section: ~15 mm (thread located on the outer side of the hole) The screw presses directly against the counterweight shaft to lock the holder in place. The original EQ2 mount uses the same locking method to secure the stock ~3.5 kg counterweight, so the clamping principle and load conditions are similar to the factory configuration.
