Brass Flush Bolt for Double Doors
The National Mfg. Gallery Series flush bolt is solid brass with a polished brass finish. It is designed to secure the inactive leaf of French, patio, wood or double doors. The sliding bolt throws one-half inch into the supplied strike. Each unit is sold individually.
Suits Inactive Door Leaf Security
This bolt suits homeowners or installers fitting a flush bolt to the edge of a secondary door. It is not for buyers who need a surface bolt, a mortise lockset or an automatic flush bolt. It is also not for doors thinner than the bolt throw or for frames that cannot accept the strike dimensions.
Check Door Edge and Strike Clearance
Verify the door edge can accommodate a six-inch by three-quarter-inch face plate. Confirm the frame has room for a two-inch by three-quarter-inch strike. Ensure the door thickness allows the half-inch throw to engage fully. Check that a sliding bolt action matches the intended operation.

Questions about this item
What type of door and existing hardware are needed to install this flush bolt?
It fits French, patio, wood or double doors and requires a mortise cut for the 6-inch by 3/4-inch face plate and a matching strike mortise for the 2-inch by 3/4-inch strike.
Will the 1/2-inch throw engage a strike cut for a longer throw on an older door?
No, the 1/2-inch throw only reaches a strike pocket cut to that depth; a deeper pocket would leave the bolt short of full engagement.
How can I confirm the bolt is operating correctly after fitting?
Slide the bolt by hand — it should move smoothly the full 1/2 inch, seat firmly in the strike and hold the door immobile without rattling.
