Electrical Cable Sleeve Feature - Made from new thickened PE material, it is wear-resistant, corrosion-resistant, smooth, and glossy. Additionally, it is very flexible and easy to bend. It is ideal for splitting, organizing, and protecting cables, preventing wear and improving the aesthetics of bending. Easily and neatly consolidate all messy wires into one cord.

Measure - Tie the wire with a rope and measure the length of the circle of the rope. 2. Count - diameter = length of the rope / 3.14. For example, if the measured rope length is 75mm, then the diameter = 75mm / 3.14 = 23.9mm. We suggest purchasing a size of approximately 24mm. Dimensions: 118.08 x 0.39 x 0.04 inches.
