The bottom brackets of a garage door are directly connected to the door's springs, which are under significant tension. Attempting to adjust or loosen these brackets without proper training can lead to dangerous situations. Therefore, it is recommended to seek the expertise of a trained technician who understands the complexities of garage door systems. Additionally, many manufacturers now incorporate tamper-resistant hardware to prevent inexperienced individuals from unintentionally loosening the brackets and compromising the door's functionality and safety.
