And then, how much for one set? Thank you, John B
Having said that I can supply you with the same function by a different company.
That flushbolt that you have is what's called constant latching whereas when the door is pushed closed that is, the inactive door, it will automatically relock.
When you open the Active Door the inactive door will remain locked until you manually release that bolt allowing the inactive door to open once again.
Please confirm that the dimension of the faceplate of the existing is six and three quarter inch tall and 1 inch wide.
Please review and advise.
