When selecting a proper floor spring, follow these key points for correct selection:

Match door weight & width
Check the finished door weight and leaf width first. Different load-bearing floor springs fit varied door specs; overweight doors cause quick hinge damage and poor closing performance.
Confirm door opening angle
Pick standard 90° stop or 180° free-swing types based on usage needs (commercial shopfronts often use 90° positioning).
Select installation environment grade
Use stainless steel waterproof models for outdoor/ wet areas like entrance doors; regular zinc alloy types work for indoor dry spaces.
Check closing & latching speed adjustment
Opt for products with dual-speed regulating valves to separately control slow closing and final lock-in speed, avoiding slamming.
Verify project usage scenario
Heavy-traffic public buildings prefer high-duty durable floor springs; home interior doors adopt light-load economical styles.

4.Floor Spring Installation Guide PRO

1. Pre-Installation Preparation

Tools & Materials

• Tools: Tape measure, spirit level, plumb bob, angle grinder, electric hammer, Allen key set, screwdrivers, marker, rubber mallet.
• Materials: Floor spring, top pivot, door patch fittings (for glass doors), anchor bolts, cement mortar, cover plate.

Inspection

• Check floor spring for damage, leaks, and model compatibility (match door weight/size).
• Verify door frame/door is square, undamaged, and the opening is clear.
• Ensure the floor is solid (concrete recommended) with enough depth for the floor spring cavity.

2. Positioning & Marking (Critical Step)

1. Determine the pivot center: The floor spring spindle center must align with the door’s bottom pivot center.
2. Setback measurement: Mark a line 30mm inward from the door’s hinge-side edge.
3. Transverse positioning: From the hinge-side wall, mark a line at door width + 3–5mm (for operation clearance).
4. Outline the cavity: Place the floor spring on the floor, align its spindle with the marked cross point, and trace its outer profile with a marker.

3. Floor Cavity Cutting

1. Cut the perimeter: Use an angle grinder to cut a 3–5mm deep groove along the marked outline.
2. Excavate the cavity: Remove concrete/ flooring inside the outline with an electric hammer or chisel. The cavity must match the floor spring’s dimensions tightly (no gaps).
3. Clean & level: Remove debris and dust. Ensure the cavity base is flat and level.

4. Install the Floor Spring Body

1. Place the spring: Lower the floor spring into the cavity.
2. Level & align: Use a spirit level to make it perfectly horizontal. Align the spindle with the marked pivot center.
3. Secure: Fix with anchor bolts or fill gaps with cement mortar. Tap gently with a rubber mallet to seat it firmly. The top of the spring should be flush with the finished floor.

5. Install Top Pivot & Door

1. Top pivot installation: Mount the top pivot on the door frame, directly above the floor spring spindle. Ensure perfect vertical alignment. For glass doors, use patch fittings (avoid drilling glass).
2. Hang the door:
   1. Lift the door (two people recommended).
   2. Insert the door’s bottom pivot into the floor spring spindle.
   3. Align the top pivot pin with the door’s top fitting and lower gently.
3. Check swing: The door should swing freely without obstruction.

6. Precision Adjustment

Vertical Alignment

• Adjust the floor spring’s 3-directional screws to keep the door vertical and the upper/lower pivot axes coincident. Use a plumb bob for verification.

Closing Speed (Hydraulic Valves)

• Main speed (180°–10°): Turn the main speed valve (marked “1”) with an Allen key. Counterclockwise = faster; Clockwise = slower.
• Latching speed (10°–0°): Adjust the latching valve (marked “2”). Set it fast enough to latch securely but slow enough to avoid slamming.
• Recommended: Total closing time 3–5 seconds.

Closing Force

• Access the spring pressure rod (remove the cover).
• Increase force: Turn the adjustment screw clockwise (1/4 turn each).
• Test: The door must close fully from 90° without rebounding.

90° Hold-Open (If Equipped)

• Open the door to 90°, slide the limit slider in the spring’s track, and tighten the screw. Test stability by opening/closing 10 times.

7. Final Installation & Testing

1. Install cover plate: Attach the stainless steel cover to protect the mechanism from dust/water.
2. Full test cycle:
   1. Open to 90° → check hold-open.
