100% Nylon - Upgraded with better and sturdier locks to prevent jamming and miss-locks, this fridge lock for kids is optimal for safeguarding access to your refrigerator or cabinet. Made from sturdy nylon and ABS plastic, this fridge door lock is force-tested to help prevent children from opening the refrigerator, especially at night. The strap is adjustable and remains effective even when fully loosened. This standard-sized lock fits French door refrigerators with a diameter of 8 to 13.5 inches. Includes an extra Velcro strap to secure the lock to the handle, allowing for easy use without removal each time. Designed for young children six and under, and some developmentally disabled adults. The webbing is made of durable nylon but is not cut-proof. Use with caution and supervision.
