floorspring

A floorspring is a type of door closer that is concealed within the floor. It is typically used for glass doors or doors that require a more aesthetically pleasing, unobtrusive door control solution. Unlike overhead door closers, floorsprings are mounted in a special housing set into the floor beneath the door. This allows for a clean, minimalist look as the mechanism is hidden from view.

Floorsprings operate by using a hydraulic or pneumatic system to control the closing speed and force of the door. They often include a delayed action feature, which allows the door to remain open for a set period before slowly closing. This is particularly useful in high-traffic areas or for accessibility. Many floorsprings also offer a hold-open function, allowing the door to be held open at a specific angle.

Installation requires a recess in the floor to accommodate the housing. The main body of the floorspring connects to the bottom of the door and to the frame or floor. They are designed to be durable and are suitable for a wide range of door weights and sizes, from interior residential doors to heavy exterior commercial doors. Maintenance usually involves occasional checking of fluid levels and seals, though they are generally designed for long service life with minimal upkeep. Floorsprings are a popular choice for architectural designs where the door hardware should be as discreet as possible.
