2×25 mm-Standard Size Collars Clamp, Quick & East Barbell Collars, Portable & Travel Friendly, Heavy Duty Performance, Securely Fastened

First time using these collar clamps but after losing my rag faffing around with spinlock collars for the umpteenth time (and repeatedly losing the rubber grommets), I decided to try them. Wow! They look fragile but they certainly do the job - so easy to slip on, clip into place and unclip when you want to change weight plates.They have rubber pads to grip the bar but their grip isn't iron-like so I wouldn't dare use them for goblet squats or dumbbell pullovers, but for horizontal barbell / dumbbell work they're great.

Nice and quick instead of spinning clips.

These are amazing. They would have been the purchase of the year for me IF I’d ordered the Olympic sized collars but I didn’t.I liked them so much though that I kept them,

I got fed up with using spinlock collars as they were making it too fiddly and time consuming to change weights, and my workout was slowed down as a result. These quick release collars are fantastic, making it so much quicker and easier. They hold pretty securely on my 1 inch bars.Unfortunately, there is one thing that lets them down. There is a small metal pin through each of the pivot points in the mechanism, and these pins are not secured in place at all. When the collars are locked, the resulting pressure keeps them in place. However when they are unlocked, the pins can easily come out of the holes, often in such a way that the pin then fouls the locking mechanism, and this has ultimately resulted in one of the collars breaking. It is also very annoying having to keep pushing the pins back in. This excellent product is sadly let down by this simple design flaw.

Does exactly what it says on the tin - Good sturdy product which is easy to get onto the weight bar and easy to maneuver - Worth buying

These seem fine for a few weeks but have now lost all their tension and won't hold the plates on the dumbbells. During a workout tonight a 2kg plate fell off and hit me in the face. I was very lucky as it was a glancing blow but I have a huge bump on my forehead. REALLY REALLY DANGEROUS AND CLEARLY NOT FIT FOR PURPOSE.

Please look at the sizing of your home or gym bars before buying these as I can imagine that people can get caught out with the differences between the olympic bar and the home gym bars diameters, these clips are great from home bars with a smaller diameter. These clips are a god send if you are sick of the spin locks coming undone but I wouldn't just use the clamps by themselves I would use these as an addition to make sure the spin lock doesn't come undone as the collars to not have rubber on the sides to help with plate spinning when doing Barbell complexes or other full range motions, I have taken an example of what i mean on the pictures. They are extremely easy to use so would definitely add them to your home gym.

I bought these a few weeks ago and I have been using them without any problems. There were some delays about delivery, I think because of COVID-19 issues, but when I raised the query a second batch were sent without any argument.I am using these on threaded dumbells bars. The plates I am using are rubber coated, which adds friction which helps keep them in place. With these plates, the collars feel very secure. I use the original screw-on retaining nuts for the minimum number of plates for warm-up (7.5 or10kg per dumbell), and then use these clamps to hold additional plates during exercise. This makes adding weight very quick. I don't lift heavy weights any more, but these clamps are comfortably strong enough to retain additional plates up to 5 kg each side of the bar for 17.5 or 20kg per dumbell. I think they would be fine for a few more kg, but I haven't got enough plates to try that.One thing to be aware of. I didn't know there are actually three different sizes of the small (non-Olympic) threaded bar, 25mm, 28mm and 30mm. These are 25mm, so you need to measure the diameter of your bars before order. When they arrived, I discovered that one set of my bars is 25mm and they work fine on these. But I also have a pair of 28mm and they don't fit these.

Ho scelto questi fermi per il bilancere da 25mm e sono rimasto molto contento per la meccanica e la praticità. Con un semplice gesto bloccano i dischi. All’interno hanno gomma, questo per confermare che la tenuta è davvero buona. In posizione di aperto, si sfila agevolmente. Non posso dire la durata nel tempo, ma non fa nessuno sforzo per lavorare correttamente. Attenzione nel scegliere la misura adatta al proprio bilancere.

Ottimi.li ho presi per bilanciere diametro 25 ed il mio e' a vite,quindi ero insicuro.ho provato e subito l inserimento e' stato un po' duro ma quando li ho chiusi,hanno preso la forma della vitona e sono fantastici.davvero da consigliare.comodi,veloci e sicuri

Perfetto, ottimo prodotto, ferma molto bene i dischi sul bilanciere . Acquistati altri tre set per altri manubri e bilancieri , dal mio punto di vista è un acquisto da consigliare

Pessimo. Nonostante fosse indicata la misura i morsetti sono piccoli per il mio bilanciere. Volevo fare il reso e mi costa più di 5€. Non solo ho ricevuto un prodotto che non rispetta le caratteristiche indicate devo pure pagare per restituirlo. Bocciato

Ottimi... diametro 25mm. Calzano a pennello sui manubri e i bilancieri. Hanno una buona tenuta e si montano/smontano in un attimo. Consigliatissimi. Belli da vedere e da usare.
