Spring collars, also known as clamp collars, are dumbbell and barbell lock nuts that have spring-like structure. This form allows spring collars to produce force when it is attached to the dumbbell or bar. In order to attach the spring collar, you must apply pressure to the handles on either side of the spring in order to expand the diameter of the collar. Easily slide the collar across the bar once the diameter has expanded enough. Once the metal is flush against the plates, you can release the handle in order to secure the collar in place. This spring collar is able to hold plates when performing dumbbell or barbell exercises.

Spring collars are very affordable which makes that as its major advantage. So if you are still starting to build your home gym, then this type of dumbbell lock is convenient for you. It also gives the advantage that it can be slid to the end of the bar swiftly with just simple adjusting the handles. This is particularly helpful especially to those who like to change weights between exercises or people who are following exercise routines that require adjusting weights.

With the collar being the nut and the bar being the bolt, spin lock collars function comparably to a nut and bolt. Hence, it must be noted that you can not buy spin lock collars without a spin lock bar to attach them to. Spin lock collars frequently come with a dumbbell or barbell bar as a complete package. The way it works is based on simple physics: force is applied against the plates and end of the bar as you tighten the spin collar. The plates also apply force back on the threads of the collar in order to hold them tightly in place. These forces are balanced, making sure that the plates and collars do not move during exercise so that potential risk for accidents are cancelled.

One of the major advantages of this type of dumbbell lock is that spin lock collars are offered as a set and hence are frequently very affordable. They are also perfect for home gym setups because they work right for lower weights. Moreover, they are a no-brainer and thus very easy to use. If the spin lock collars are attached loosely, you will immediately feel the weights plates starting to slide. This is beneficial because you can consciously know if something wrong is happening, and you can safely put down the bar and readjust the collar in order to prevent any accidents.

One of the most common disadvantages of the spin lock collars is that people find it hard to secure them tight enough. This can be frustrating to some people because they keep finding the collars frequently slipping, which causes the exercises to be uncomfortable due to weights moving around on the end of the bar. One can easily make sure that this does not happen through grabbing the outermost plate and twisting it clockwise, ensuring that the bar itself does not turn. If the collar turns as well, it means the collar is tight up against the plate, and you can tighten it up a little bit more. This step ensures that the spin collar is tightly put in place.

Snap lock collars with good qualities are amazingly sturdy. Those qualities are usually made out from metal rather than nylon or plastic. These metal snap collars are a more durable option and are usually utilized for olympic lifting.
