Tensioning devices are tools used to apply tension to cables, ropes, or other materials. They help maintain the desired level of tightness, ensuring that structures or systems function properly. Common examples include turnbuckles, tensioning clamps, and ratchet straps, which are often used in construction, rigging, and transportation. These devices are essential for safety and stability in various applications. By keeping materials taut, tensioning devices prevent sagging or loosening, which can lead to failures or accidents. Proper use of these tools is crucial in industries such as construction, maritime, and automotive.
