The constant tension spring clamp is just that – a constant tension spring clamp! It has a rigid metal handle, keeping it strong and durable. The 15mm thickness makes this clamp ideal for heavy duty applications, whilst the angled ends hold both ends of your band securely in place, regardless of orientation. Kept clean and dry when not in use with the help of an included bag (10 packs per bag).

The Pat CLS-014 constant tension spring clamp is a simple and effective clamping device to secure your horse’s legs offering a quick and controlled release of the hind leg for treatment. The constant tension springs allow for an even application of pressure across the sides of the limb, making this a great alternative to equine boots or bandages. Constant tension springs have an inherent damping characteristic, allowing a greater load to be achieved. A high quality spring is required for the full benefits of constant tension. 

This clamp is designed to be used with a PAT threading tool. The constant tension spring makes the clamp easier to use and more consistent in pull pressure. All you need to do is wait until the threading tool has created one wrap of thread, then add another wrap without having to hold tension on the hydraulic ram or any other type of clamp during insertion or removal from the part being threaded. It's a huge time saver when working on multiple parts with complex threads.
