Shootbolt Basics

A shootbolt is a slim, vertical locking bolt used in multipoint locking systems, most commonly at the top and bottom of a door. When the handle is lifted or the key is turned, the shootbolts extend (or “shoot”) into the door frame or threshold, helping secure the door along its full height rather than just at the handle level.

 

Why Shootbolts Are Used

Shootbolts add vertical locking strength. Instead of relying only on a central latch or hook, they anchor the door at the top and bottom, reducing flex and improving resistance against forced entry. This is especially important on tall uPVC, aluminium, and composite doors where movement can occur over time.

• Improve overall door stability
• Help keep the door square in the frame
• Increase security at weak points (top and bottom)

How a Shootbolt Works

Shootbolts are driven by the multipoint lock’s gearbox through connecting rods. When the handle is lifted (on lift-to-lock systems) or the key is turned (on key-wind systems), the rods move vertically, pushing the shootbolts outward into their keeps.

Unlike hooks or rollers, shootbolts usually move in a straight line with no cam or rotation. They rely on precise alignment with the frame keeps, which is why dropped doors or worn hinges can cause shootbolts to miss the keep or feel stiff.

Shootbolts vs Other Locking Points

Not all multipoint locks use shootbolts. Some use hooks, deadbolts, rollers, or a combination of these. Shootbolts are most often paired with hooks or latches to balance vertical strength with lateral pull-in.

• Shootbolts: Vertical security and stability
• Hooks: Pull the door tightly into the frame
• Rollers: Compression and alignment rather than security

Replacement and Common Issues

Shootbolts themselves rarely snap, but they can bind or fail to extend if the door has dropped, the keeps are misaligned, or the gearbox is worn. In many cases, the fix isn’t the shootbolt at all, but adjustment of hinges or replacement of the central gearbox that drives the system.

When identifying a replacement multipoint lock, the presence and position of shootbolts matters. Different manufacturers use different spacing, bolt lengths, and profiles, so measurements must be checked carefully. For a clearer overview, see our guide on how multipoint lock systems work.
