A floor spring free door is a type of door operated by a floor-mounted spring mechanism (floor spring), allowing it to automatically close after being pushed open from either side. Designed for convenient, hands-free use, it is commonly installed in public spaces like hotels, office buildings, and shopping malls due to its smooth operation and durability. The floor spring system absorbs impact, ensuring gentle closing and reducing wear, making it a practical choice for high-traffic areas where easy access and reliable performance are key.
