1. Right size: The R-shaped pool cover clip is approximately 4.7 inches long, 1.3 inches wide, and 0.6 inches high, and each weighs around 0.4 ounces. The maximum opening size of the A-shaped spring clip can reach about 2 inches, and it is approximately 4.61 inches long. 2. Sturdy and reliable: These craft clips are made of plastic materials and thick springs. They are sturdy and not prone to breaking, with relatively strong grip, high tension, and good flexibility. Spring clips can play a role in fixing and stabilizing during the assembly and reinforcement process. 3. Used in combination: You can use the R-shaped above-ground pool cover clips to clamp the pool railing at intervals, but they may not be suitable for pools with soft edges. When you find that the clips are not firmly fixed or the edges cannot be clamped by the R-shaped clips, you can use the A-shaped plastic clips for fixation to provide additional reinforcement for the pool cover. 4. Windproof and rainproof: The above-ground pool cover clips and 2-inch spring clips work together to withstand adverse weather. You don't have to worry about the clips melting in high temperatures on sunny days, nor about the pool cover being blown up by the wind. 5. Sufficient quantity: The set includes 30 winter pool cover clips and 10 A-shaped plastic clips, which is a practical combination to protect the pool from rain, sunlight, and wind.
