FAQ

How do I adjust the closing tension on these spring hinges?

Use the included tension adjustment pin or wrench to increase or decrease spring tension. Turn clockwise for stronger closing force and counterclockwise for lighter closing force.

What door weight do these hinges support?

Depending on size, they support doors weighing 10-30kg. The 6-inch hinges are recommended for heavier commercial doors.

Can these hinges be used outdoors?

We recommend using them in covered or indoor environments. For outdoor use, consider adding weatherproof protection or selecting stainless steel variants.

How many hinges are needed per door?

For standard saloon doors, two hinges (one pair) are typically sufficient. For heavier or taller doors, three hinges may be recommended.
