Bottom Pivot Hydraulic Door Closer – Floor Spring with Hold Open for Frameless Glass Door
Heavy-duty frameless glass doors in modern commercial spaces and high-end residences require a reliable door control system. A bottom hydraulic door closer (also known as floor spring) not only bears the door weight and rotation but also provides smooth closing, cushioning silence, and hold-open function. This glass door bottom hydraulic closer integrates three core functions: hydraulic closing, bottom pivot, and 90-degree hold open. It is the ideal choice for hotels, malls, office buildings, and villa glass doors.

This floor spring uses a high-strength die-cast aluminum body with a precision-honed hydraulic cylinder, ensuring oil flow stability and no leakage. The bottom pivot is made of stainless steel, corrosion-resistant and high load capacity. Closing speed is controlled by two independent adjustment valves for “closing zone” and “latching zone” to suit different environments. The 90-degree hold open function allows the door to stay open when opened to 90°, convenient for moving large items or maintaining ventilation. The cover plate is brushed stainless steel or plated, matching the glass door style and providing waterproof and rust-proof properties.
3. Application Scenarios Complete Example
Hotel Lobby Entrance : With 12mm frameless glass door, handling high foot traffic. Door holds open at 90° for luggage carts.
Retail Store Front : Heavy glass door needs hydraulic cushioning to prevent impact and extend door life.
Office Building : Meeting room glass door requires silent closing without disturbing meetings.
Hospital/Clinic : Adjustable slow closing prevents pinching patients.
Villa Courtyard : Glass door with floor spring is aesthetic and wind-resistant.
4. Installation Instructions (Step-by-Step)
Tools required: Rotary hammer, spirit level, measuring tape, cement mortar, Phillips screwdriver, template paper.
Step 1 – Prepare recess
Mark and cut a recess of approx. 300×300×80mm (L×W×D) in the floor according to the provided template. Ensure the recess bottom is flat and clean.
Step 2 – Embed the box
Place the floor spring body into the recess. Adjust the level so the top surface is flush with the finished floor (0-2mm below). Secure with cement mortar, maintaining vertical and horizontal level.
Step 3 – Install shaft and top pivot
After mortar cures, install the stainless steel shaft. Install the top pivot on the door frame or upper transom. Ensure vertical alignment of top and bottom pivots.
Step 4 – Hang the glass door
Align the bottom hole of the tempered glass door with the floor spring shaft, then insert the top pivot. Adjust door verticality and gaps (side gaps 2-3mm, top/bottom gaps 3-5mm).
Step 5 – Adjust closing speed
Use the provided Allen key to turn the adjustment valves. Typically clockwise slows down, counterclockwise speeds up. Adjust “closing zone” (180°-15°) first, then “latching zone” (15°-0°).
Step 6 – Test hold open
Open the door to 90° and check if it stays in position. If not, fine-tune the internal hold open cam (refer to manual).
Step 7 – Install cover plate
Snap on the stainless steel cover plate for a clean finish.
Professional tip: Floor spring installation requires precise leveling. Professional door hardware installer recommended. For doors over 120kg, consider the heavy-duty version.
