Buyer FAQs
What door size can the F-8300 support?
The listed limits are 1000 mm door width and 100 kg door weight. Both limits must be considered together. Send your door details so the configuration can be checked.
Can I adjust the closing speed?
Yes. Two adjustment valves control the 90°–20° and 20°–0° closing ranges separately. Follow the installation instructions when making adjustments.
Does this floor spring hold the door open?
The listed hold-open position is 90°. Non-hold-open and double hold-open options are available on request. Specify the required version when requesting a quotation.
Can it replace an existing floor spring?
Compatibility cannot be confirmed from the model name alone. Send the existing unit’s dimensions, spindle connection and fitting photos for comparison.
What is required for a quotation?
Please provide the door dimensions and weight, hold-open requirement, quantity, project country, delivery address and postal code. These details help us check the configuration and calculate shipping.
