We have a project of changing the hardware on the doors in the house from brass to Satin Nickel. The problem that I have is that the hinges on the doors appear to be proprietary and I can't find a match in Nickel.

I have found that Deltana makes a hinge that matches the pattern but they don't carry it in Nickel, or at least the vendors on-line don't offer it in Nickel.

Here is a link to the hinge:

Link to spring loaded version:
https://deltana.net/catalog/steel-st...l-listed/print

Needs to be 4 x 4 x w/5/8 inch Radius and have a "Bench Mark" hole pattern.
The spring-loaded (self-closing) version that I removed from on of the doors has a brand name of "Boomer", and the non spring loaded hinges have brand name of "Seigles".

From what I can tell, BenchMark is a door manufacture with a specific/proprietary hole pattern that only a handful hinge manufactures make.

I need a few that are spring loaded and some that are not.

If anyone could help me find a version of these hinges in Nickel, it would be greatly appreciated.

Thank You.
