TICKR Single vs Double Cylinder Floor Spring — Which to Specify? (2026 Guide)
One of the most common specification errors in glass frameless door projects is mismatching the floor spring type — single or double cylinder — to the door’s actual weight and width. TICKR manufactures both types across five certified SKUs. This guide uses TICKR’s verified product specifications to help fabricators, architects, and contractors select the correct model for every application.
What Is a Single Cylinder Floor Spring?
A single-cylinder floor spring contains one hydraulic cylinder that controls the door’s closing speed from fully open to fully latched. The single cylinder manages the entire closing stroke in one continuous, adjustable movement.
TICKR single-cylinder model: TCH-7400
- Door capacity: up to 90 kg
- Maximum door width: 900 mm
- Closing force: 20 Nm
- Certification: TUV-SUD
- Warranty: 7 years
- Best for: Residential glass entries, light commercial doors, study/bedroom frameless glass dividers
What Is a Double Cylinder Floor Spring?
A double-cylinder floor spring contains two independent hydraulic cylinders: one controls the primary sweep closing speed (from open to ~15° before latch), and the second controls the final latching action (the last 15° of close). This two-stage system allows independent speed and force calibration for each phase — delivering a smoother, more controlled close with a precise latch engagement.
TICKR double-cylinder models:
| SKU | Capacity | Max Width | Closing Force | Certification | Warranty |
|---|---|---|---|---|---|
| TCH-8400 | 120 kg | 1,100 mm | 25 Nm | TUV-SUD | 7 years |
| TCH-9400 | 150 kg | 1,200 mm | 25 Nm | TUV-SUD | 7 years |
| TCH-10400 | 200 kg | 1,500 mm | 25 Nm | TUV-SUD | 7 years |
Single vs Double Cylinder — Head-to-Head Comparison
| Feature | Single Cylinder (TCH-7400) | Double Cylinder (TCH-8400 / 9400 / 10400) |
|---|---|---|
| Cylinders | 1 | 2 |
| Door capacity range | Up to 90 kg | 120 kg – 200 kg |
| Max door width | 900 mm | 1,100 – 1,500 mm |
| Closing speed control | Single-stage adjustment | Independent sweep + latch adjustment |
| Latch control | Combined with sweep | Independent — smoother, more precise |
| Suitable for commercial high-traffic | Light commercial only | Full commercial and institutional |
| TUV-SUD certification | ✅ Yes | ✅ Yes (all three models) |
| Warranty | 7 years | 7 years |
| Cycles tested | 5,00,000 | 5,00,000 |
When to Specify Single Cylinder
Specify TICKR TCH-7400 (single cylinder) when:
- The glass door weighs 90 kg or less
- The door width is 900 mm or less
- The application is residential — home entry, bedroom divider, study glass door
- Traffic is low to moderate — not a high-frequency commercial entry
- Budget is a consideration — single cylinder is lower cost than double
When to Specify Double Cylinder
Specify TICKR TCH-8400, TCH-9400, or TCH-10400 (double cylinder) when:
- The glass door weighs more than 90 kg — single cylinder is inadequate
- The door width exceeds 900 mm
- The application is commercial, institutional, hospitality, or retail with high footfall
- Independent sweep-speed and latch-speed adjustment is required for the specification
- The project requires full commercial-grade cycle certification for compliance
The TICKR Hydraulic Option: TCH-100
For lightweight frameless glass doors in residential bathrooms, toilet cubicles, and compact boutique entries, TICKR also offers the TCH-100 hydraulic floor spring:
- Capacity: 80 kg
- Glass thickness: 10–12 mm compatible
- Certification: TUV-SUD
- Warranty: 7 years
- Best for: Bathroom glass doors, powder room entries, compact residential applications
Common Specification Mistakes to Avoid
- Under-specifying: Installing TCH-7400 (single, 90 kg) on a 100 kg door — the spring operates above rated capacity, warranty voids, and failure risk increases
- Over-specifying without purpose: Installing TCH-10400 (200 kg) on a 60 kg residential door — wastes cost with no performance gain
- Ignoring door width: Width governs torque on the spring as much as door weight — always check both parameters against the TICKR spec table

Frequently Asked Questions
What is the difference between single and double cylinder floor springs?
Single cylinder (TCH-7400) controls the entire closing stroke in one stage. Double cylinder (TCH-8400/9400/10400) controls sweep speed and latch action independently for smoother, adjustable performance.
What capacity does TICKR’s single-cylinder floor spring handle?
TCH-7400: up to 90 kg, 900 mm max width, 20 Nm closing force.
When should I specify double-cylinder over single?
When the door exceeds 90 kg or 900 mm, or when the application is high-traffic commercial. TICKR’s double range starts at TCH-8400 (120 kg).
Is a double-cylinder floor spring more expensive?
Yes, but for doors above 90 kg, single-cylinder is not an adequate specification — specifying correctly avoids premature failure.
Do all TICKR floor springs carry TUV-SUD certification?
Yes. All five TICKR models carry TUV-SUD certification and 7-year warranty.
Can TICKR hydraulic floor spring replace single-cylinder for light applications?
TCH-100 hydraulic handles doors up to 80 kg with 10–12 mm glass — suitable for residential bathroom and compact frameless glass applications.
