Assuming you are referring to pegs used for hanging laundry or similar purposes, there are several things you can do to prevent them from breaking:
Choose the right type of pegs: Not all pegs are created equal. Some are made from flimsy materials and are more prone to breakage. Look for pegs that are made from sturdy materials like plastic, metal or wood.
Don't overload the pegs: If you try to hang too much weight on a single peg, it is likely to break. Spread out your laundry over multiple pegs instead of trying to hang everything on one.
Use the right size pegs: If you try to force a thick item onto a narrow peg, it can cause the peg to break. Make sure you are using the right size peg for the item you are hanging.
Avoid exposure to extreme temperatures: If you leave your pegs outside in extreme heat or cold, it can cause the material to become brittle and more likely to break. Store your pegs in a dry, cool place when not in use.
Don't leave them outside: Leaving your pegs outside in the sun and rain can make them brittle and more likely to break. Always bring them inside after use and store them properly.
Choose pegs with a strong spring: The spring mechanism in some pegs is weaker than others. Look for pegs with a strong spring that can withstand the weight of your laundry without breaking.
By following these tips, you can help prolong the life of your pegs and prevent them from breaking.
