THETOPHK PRODUCT QUESTIONS · FLOOR SPRINGS & PATCH FITTINGS
Compare the listed specifications of F-550, F-2400 and T-010 before preparing a glass-door hardware inquiry. These answers use their current THETOPHK product descriptions.
1. Which listed THETOPHK floor spring has a 300 kg door-weight specification?
The F-550 hydraulic floor spring lists a suitable door weight of 300 kg and an applicable door width of 1500 mm. Share both door weight and width when requesting selection advice; matching one dimension alone does not confirm suitability.
2. How do the F-550 and F-2400 door-weight specifications compare?
The F-550 lists 300 kg, while the F-2400 lists 250 kg. Both list an applicable door width of 1500 mm. These are model-specific specifications, rather than a rating for every THETOPHK floor spring.
3. Which of these models lists a replaceable spindle head?
The F-550 product page states that its spindle head is replaceable. The F-2400 page states that its spindle head is not replaceable. For a replacement project, also confirm the spindle connection and mating fitting before ordering.
4. Do the F-550 and F-2400 have the same maximum opening angle?
No. The F-550 lists a maximum opening angle of 180°, while the F-2400 lists 130°. Check the required door swing and available clearance against the selected model before purchasing.
5. What hold-open options are listed for the F-550?
The F-550 lists a 90° hold-open position. Its product description also states that non-hold and double hold-open versions are available on request. Specify the required version in your inquiry; do not assume every supplied unit has all options.
6. Can I request an F-2400 version without hold-open?
Yes. The F-2400 description lists non-hold and double hold-open options on request, alongside the listed 90° hold-open configuration. Ask THETOPHK to confirm the exact version in the quotation and order specification.
7. Which closing-speed ranges are listed for these two models?
Both product pages list two closing-speed valves: one for 90°–20° and another for 20°–0°. Use the installation instructions for the supplied model when setting them; the product pages do not provide a complete adjustment procedure.
8. What installation adjustment is listed for the F-550 and F-2400?
Both descriptions state that left/right, forward/backward and up/down adjustment is available at 6 mm. Confirm the installation drawing and the meaning of that adjustment allowance for your floor box before preparing the opening.
9. What glass thickness is specified for the T-010 patch fitting?
The T-010 patch fitting glass door clamp lists a suitable door thickness of 10–12 mm. Confirm the actual glass thickness, fitting position and connection details; appearing in the same product category does not establish compatibility with a particular floor spring.
10. Which materials and finishes are listed for the T-010?
The T-010 lists aluminum alloy and stainless steel as its main materials. Listed finishes are bright polish, satin finish and titanium gold plated. State the finish required in your inquiry and request confirmation for the supplied configuration.
