This is the cover plate to a Meteor floor spring that I was called out to.
The Meteor had a broken spring set. The pieces of which were trapping the check/pivot so the door would not open past the 20 degree mark.
The broken Meteor was replaced from our stock.
The lovely mahogany doors leading into the Buxton Opera House are now back on and functioning correctly.
As there is so little information out there with regard to door closers, especially vintage and antique model floor springs, I thought I would start this blog.
