Multi-point locking system and astragal

An entryway comprising, a sill spanning a bottom of the entryway and having a lower bolt opening, a normally inactive door panel, a normally active door panel, and an astragal mounted to and extending along an unhinged edge of the normally inactive door panel, the astragal comprising:

• an elongated body having opposite top and bottom;
• a first shoot bolt at one end of the elongated body and being movable between a retracted position substantially withdrawn into the elongated body and an extended position projecting in an axial direction from the one end of the astragal;
• a second shoot bolt at the opposite end of the elongated body and being movable between a retracted position substantially withdrawn into the elongated body and an extended position projecting in an axial direction from the opposite end of the astragal;
• a seal block substantially surrounding the first shoot bolt and being movable between a non-sealing position substantially withdrawn into the elongated body and a sealing position projecting in an axial direction from the one end of the elongated body, the seal block having a bolt passage therethrough, the first shoot bolt being slidably disposed through the passage;
• a shoot bolt actuator accessible on the elongated body and being movable between an unlocked position and a locked position, the shoot bolt actuator being linked through a plurality of actuator links to the first and second shoot bolts and to the seal block, the actuator links being configured upon movement of the shoot bolt actuator from its unlocked position toward its locked position to drive the seal block toward the sealing position until the seal block engages against the sill, to drive the first shoot bolt from the retracted position toward the extended position, and to drive the second shoot bolt from the retracted position toward the extended position;
• a first spring configured to bias the first shoot bolt;
• and
• a second spring configured to bias the seal block, wherein the second spring has a first length when the seal block is in the non-sealing position and the shoot bolt actuator is in the unlocked position, and
• wherein the second spring has a second length when the seal block is in the sealing position engaged with the sill and the shoot bolt actuator is in the locked position, the first length being longer than the second length.
