The slimmest heavy-duty collars available!

After years of searching for an extremely durable collar slim enough for use on dumbbells, we found that Bulldog Collars take up too much space.
Unable to find a suitable option, we decided to machine our own!
These collars are exceptionally heavy-duty and, when clamped onto the bar, remain completely solid thanks to the two M12 locking bolts.
Best of all, they are only 20 mm thick, minimizing the space they occupy on your standard Thick Grip Dumbbell Handles.

With the Watson Dumbbell Collars, our 16” long Thick Grip Dumbbell Handles can be loaded to 60 kg using 5 kg cast plates or 35 kg using 2.5 kg cast plates (as shown in the picture). This design ensures the dumbbells remain compact, allowing for the use of much shorter handles than with any other collar.
Our heavy-duty Dumbbell Collars are essential for anyone serious about their dumbbell training.
Sold as a pair and complete with an Allen key.
