The key advantage of this hydraulic floor spring is its "non-digging" design. Traditional floor springs require a pit depth over 80mm, while this product uses an ultra-thin cement box requiring only a shallow slot, greatly reducing floor damage. The ultra-thin body is 30% thinner than同类产品, and the finished floor cover sits flush with tiles for a clean look.
Internally, an imported spring has passed 50,000 fatigue cycles with no degradation. The low-temperature hydraulic oil ensures smooth door operation even at -40°C, ideal for cold climates or cold storage warehouses. The high-strength anti-leak configuration withstands damage from strong winds or external impact.
The adjustable cement box allows the floor spring body to move ±5mm horizontally in both directions, and vertical adjustment of ±2° via screws. This greatly reduces installation precision requirements – even if the original slot is off, it can be easily corrected.
The changeable head allows the product to adapt to different door pivot standards in Asia, Europe, and the Middle East, allowing one stock to serve multiple markets.

3. Application Scenarios Complete Example
Hotel Lobby Entrance : With 10-12mm frameless glass door, 140° wide opening for luggage carts.
Office Building Glass Door : -40°C low-temp oil ensures winter outdoor door operation.
Retail Store Front : Ultra-thin, aesthetic SS cover flush with tiles, no tripping hazard.
High-end Apartment Entry : Non-digging installation preserves underfloor heating or marble.
Hospital, School : Silent closing, adjustable speed to prevent pinching.

4. Installation Instructions (Step-by-Step)
Tools required: Angle grinder, spirit level, electric drill, cement mortar, Phillips screwdriver, Allen key, template.
Step 1 – Cut shallow slot (non-extensive excavation)
Using the provided template, cut a shallow slot slightly larger than the cement box (typically L250mm x W180mm x D50-60mm). Excavation volume is reduced by about 40% compared to traditional floor springs (80mm+ depth).
Step 2 – Place adjustable cement box
Place the cement box into the slot and level it. Adjustment screws on the box allow ±5mm movement in length and width. Fix the box with quick-setting cement but keep adjustment screws movable.
Step 3 – Install floor spring body
Place the floor spring body into the cement box. Use the box adjustment to align the pivot center with the door's pivot center. Use a spirit level to ensure the body top surface is flush with finished floor (0-1mm below).
Step 4 – Secure and connect pivot
Tighten the box fixing screws. Insert the door's bottom pivot pin into the floor spring pivot hole. If using Spider Fittings or Glass Spigots from our curtain wall accessories, ensure vertical alignment.
Step 5 – Adjust door verticality
Use the fine adjustment screws on the floor spring body to correct vertical alignment by ±2°, achieving a uniform gap between door and floor (recommended 3-5mm).
Step 6 – Adjust closing speed
Use an Allen key to adjust the two speed valves: one for 180°-15° closing zone, and one for 15°-0° latching zone. Clockwise slows down, counterclockwise speeds up.
Step 7 – Install decorative cover
Finally, snap on the stainless steel cover plate (optional SS201/SS304 satin or polish).
Professional tip: For top pivot needs, check our Shower Door Pivot series. For glass doors heavier than 100kg, please contact us for a heavy-duty version.

Customer voice: A facility manager in a high-end office in Manila said: “Installing traditional floor springs always meant destroying marble floors, which owners hated. This non-digging product only required a shallow slot, and the adjustable box helped us correct installation errors easily. Two years later, no oil leaks and closing speed remains stable.”
6. Use Cases – Philippines (Detailed & Authentic)
Case 1: BGC, Taguig, Manila – Grade A Office Tower
Project : One World Place, lobby and elevator hall glass doors in a 30-story office.
Quantity : 18 sets of non-digging hydraulic floor spring (SS304 satin cover).
Installation type : Shallow slot, with 10mm tempered glass door.
Feedback : Engineering Manager Mr. Reyes: “BGC has strict controls on construction noise and dust. The non-digging nature of this hydraulic floor spring let us complete installation over a weekend with almost no damage to existing flooring. The 140° opening passed fire safety inspection easily. After 18 months, no oil leaks and adjustment valves remain tight.”
Result : 30% installation time saved; received green construction recognition from the owner.
Case 2: Cebu City – Beachfront Resort Hotel
Project : Shangri-La Mactan Resort & Spa, restaurant and pool area glass doors.
Quantity : 12 sets of non-digging floor spring (SS304 polished cover).
Special requirement : High salt-mist coastal environment + high humidity and rain, requiring rust and water resistance.
Feedback : Hotel Maintenance Supervisor Ms. Santos: “Coastal environments corrode hardware quickly. This floor spring’s SS304 cover and anti-leak design are very reliable. Surprisingly, even during Cebu’s hottest days, the closing speed didn’t increase (hydraulic oil stable). The changeable head is also convenient – some of our doors use European standard spindles, we just swapped the head instead of buying new units.”

Case 3: Davao City – Large Mixed-Use Mall
Project : Abreeza Mall, main store entrances and fire exit glass doors.
Quantity : 34 sets of non-digging hydraulic floor spring (SS201 satin).
Installation type : Shallow slot + adjustable cement box, with 12mm fire-rated glass doors.
Feedback : Mall Operations Manager Mr. Tan: “The mall sees huge foot traffic daily – thousands of door cycles. The imported spring in this non-digging door closer remained strong after two years, no weak or sticky closing. The adjustable box also solved several legacy alignment issues from previous installations. The maintenance team finds speed adjustment very simple – just an Allen key and a few seconds. We will use this product for phase two.”
Internal link : For glass doors taller than 2.4m, pair with Shower Door Support Bar / Stabilizing Bar for horizontal reinforcement.
7. Structured FAQ (Topic Cluster)
Q1: Does this “non-digging” floor spring really require no digging?
A: Compared to traditional floor springs that need a 80mm+ deep pit, this product only needs a shallow slot (approx. 50-60mm) with an adjustable cement box – we call it “minimal excavation” or “non-digging.” The advantage is especially clear for finished floors.
Q2: What door weight is it suitable for?
A: Maximum door weight 100kg, door width ≤800mm, door height ≤1100mm. For larger doors, please contact us for a heavy-duty version.
Q3: What is the benefit of low-temperature hydraulic oil?
A: Ordinary hydraulic oil thickens below 0°C, causing slow or failed closing. This product uses -40°C low-temp oil, maintaining normal closing speed in cold storage or freezing climates.
Q4: What is the adjustment range of the cement box?
A: ±5mm horizontally (both length and width); ±2° vertically (zero position). This greatly reduces installation precision requirements, allowing easy correction even if the original slot is misaligned.
Q5: Can it be used outdoors or in coastal environments?
A: Yes. Choose the SS304 stainless steel cover for excellent rust resistance. The anti-leak body configuration also withstands rain, wind, and temperature changes. Regular cleaning of the pivot area is recommended.
Q6: Does the 2-year warranty cover oil leakage?
A: Yes. Any non-artificial quality defect within 2 years (including oil leakage, spring failure, valve damage) is covered by free replacement. Contact us via online technical support for quick processing.
Q7: Is there a video installation guide?
A: Welcome to visit our YouTube channel for detailed demonstrations: Official Hardware Channel
