Accurate No. 04 Transom Bolt

The transom bolt is a mechanical device, mortised into the header of a double door, that contains a spring-loaded ball on one end and a round bolt on the other end that interact with a catch on the top of the active door and a strike on the top of the inactive door, respectively. When the ball is depressed the corresponding bolt projects and as the ball is released the bolt retracts, similar to a seesaw system.

The purpose of the transom bolt is to allow a pair of doors to open and close together to gain full use of the entire opening without the necessity of releasing and securing the inactive door after every operation. The transom system allows both doors to be opened virtually simultaneously upon retracting the conventional latch. The doors can be closed together as long as the inactive door is closed slightly ahead of the active door.

Applications

Transom bolts are especially ideal for small double door situations such as bedrooms, master baths, closets, French doors, patio doors and offices. They are most commonly used on interior doors but can be utilized for exterior doors where UL fire ratings are not required. 

The transom facilitates the elegance of double doors while maintaining practicality through the ease of operation:

  • Far more convenient than manual flush bolts which require a manual release or manual locking for every simultaneous opening or closing of a pair of doors
  • Superior to automatic flush bolts in aesthetics, less exposed hardware, smoother operation and much easier to install
  • Ball catch on top of active door is easily adjustable (with screwdriver) to account for variation of door to header clearances
  • As opposed to standard ball catches, transom bolts allow conventional locks to be used while simultaneously opening and closing doors.

Operation

The transom bolt requires the inactive door to be closed prior to the active door. With the inactive door already shut, the active door is closed and the adjustable catch at the top of the active door depresses the ball in the header throwing the corresponding bolt into the strike at the top of the inactive door. Now, both doors are secured in the closed position (although a conventional latch should be used in conjunction with the transom as well.)

When the active door is opened, the ball is released retracting the bolt in the inactive door and freeing both doors.
