2/10 Security Rating

The ASEC Necked Barrel Bolt is a cranked surface-mounted security bolt specifically designed for use on stepped door frames. Unlike standard straight barrel bolts, the cranked or "necked" profile allows the bolt to bridge the gap between an offset door and its frame, making it the essential solution for installations where the door face and the frame are not flush.

Typical applications include timber doors, windows, and cupboards where additional manual security is required. It is frequently used as a secondary locking point to prevent unauthorised opening from the inside or to secure outbuildings and internal storage areas. The bolt is surface-mounted, which simplifies the installation process on both replacement projects and new builds.

Please note: This bolt is intended solely for stepped frames. If the door sits flush with the frame, a straight barrel bolt should be used instead. The unit is supplied as a complete set including the bolt assembly, matching keep, and necessary fixing screws for a standard timber installation.

FAQs

Necked barrel bolts feature a cranked or offset design specifically for use on doors with a stepped frame. The neck allows the bolt to reach past the frame's edge to engage with the strike plate when the door and frame are not on the same level plane.

No, this necked version is designed specifically for stepped frames. If your door and frame are flush (at the same level), this bolt will not function correctly, and you should opt for a standard straight barrel bolt instead.

This 25mm wide bolt is available in four different lengths to suit your specific door requirements. You can also select between two high-quality finishes:

  • Polished Brass
  • Chrome

Yes, each ASEC Necked Barrel Bolt comes complete with all the necessary fixing screws, making it ready for installation as soon as it arrives.
