The quantity is sufficient for your daily replacement and use needs. You can use them on all switches and outlets in your home, making it a very economical and practical choice. You don't have to worry about not having enough outlet spacers. [User-Friendly Twist Spacers] The twist outlet spacers are 20*20 cm in size and 0.38 cm thick. The stackable, twisted design ensures that your outlets are installed securely. Each spacer can be stacked to the desired thickness to ensure a perfect fit, and you don't need any tools to remove them. The thin plastic joint can be easily torn off by hand. In addition, they can be slightly compressed if necessary for a perfect fit. [Easy to Install] You only need a screwdriver to remove the outlet you want to repair. Then stack the electrical box spacers to the desired thickness, place them behind the screw, and tighten the screw. These spacers are more practical and environmentally friendly to use than traditional cylindrical sleeve spacers and cause no waste.
