The Pure Blue Collar Clamps - 4 Sizes

Firstly, regarding the sizes (1 pair, 2 pair, .... 5 pair), apparently a single clip counts as 1 pair. So if you order "2 pair" you will literally only get two clips. Secondly the clip is very loose on my standard 1 inch dumbells with screw threading, and can be pulled off with relative ease, so I would not trust these with any kind of weight on the bar. Thirdly the recieved item was different to the advertised images (see my attached images for reference) and does not have the tab which makes them slightly harder to use. Disappointing!

I am using these on the opti vinyl 25kg barbell (1 inch barbell) that comes with a spin locks that take forever to get on and of. I put these spring clips on and they fit perfectly and are very secure making it far quicker and easier to change the weights between exercises. One very happy customer!

These are very poor quality - and quite frankly a dangerous product. They come loose with any sort of pressure from the weights on the bar, and I can slide them off with my hands when they are clamped on. Product is also not as pictured, pictures show a locking clip/mechanism - product received does not have this. I also ordered 2 pairs initially - I only received 2 clips, and after looking in to it in detail apparently "pairs" means 1 clip. False Advertising, Bad Product. DO NOT BUY.

Item delivered does not match the images. There is no secondary locking mechanism as shown in the images on the item. This is a much cheaper alternative and is loose on my 1 inch York bars.

Perfect fit for my 1” threaded barbell. Far easier to switch between weights than screw on.

Fits ok for normal use. Not as sturdy as spinlock collars, but a lot faster to put on and take off for things like pyramid sets.

How is this "amazon recommended".Its too loose, slips of so is dangerous.Avoid

Purchased these as it was too slow to change weights with screw thread bar. Will use these to secure extra weights when required. Arrived promptly and product was exactly as described.
