Picking Out Window Locks​​

• Measure from the front of the top meeting rail (where the bottom of the top window and the top of the bottom window meet when the window is closed) to the pane of glass. 

  • The keeper must fit within this dimension.

• If the meeting rails are even where the lock mounts, any lock will work. 

  • If they are not even:  A piece of wood can be used under the lock or keeper to level things out.  A better alternative is our side mounted lock, banjo lock or combination lock/lift.

• If you want to lock the sash in the closed and in any open position, use a banjo lock. 

  • It also pushes the sashes tightly together to eliminate air gaps or rattles.

• If you are adding a lock and a single window lift, the combination lock/lift may save some $$

• For two over two sashes, single locks are OK mounted on either side.

  • Mount on the same side all around the room.

• For triple hung or walk out windows, the side lock is a good choice.
