What it is and who it fits

A solid brass surface bolt with a polished brass finish designed for casement windows and French, twin or Dutch doors. The Gallery Series hardware suits period restorations and new builds where matching traditional door furniture is required. It is not for buyers who need a lockable bolt or a flush-mounted alternative.

Deciding specification

The extra-long throw is held in position by a tension spring so the bolt stays extended or retracted without rattling. This spring-loaded action is the feature that determines whether the bolt will operate reliably on tall or frequently used doors.

Installation and common issues

Concealed base plates and both universal and mortise strikes are included for flexible fitting. The most common issue is misaligned strike placement, which prevents the long throw from engaging cleanly and can cause binding on the door edge.

Highlights

  • Solid brass construction resists corrosion
  • Polished brass finish adds traditional style
  • Extra long throw secures tall doors and windows
  • Tension spring holds bolt firmly in place
  • Concealed base and dual strikes simplify installation

Questions about this item

How does the 4 inch length translate to the bolt throw on a door or window?

The 4 inch measurement is the overall length of the surface bolt; the extra-long throw extends deep into the strike for secure latching on casement windows or French doors.

What mounting method does the concealed base use and which strikes are included?

The concealed base mounts on the surface with screws hidden beneath the cover, and both universal and mortise strikes are supplied for flexible installation.

Will the solid brass bolt and polished finish hold up on an exterior French door without marring the wood?

Solid brass construction resists corrosion on exterior doors, the polished brass finish withstands weather, and the design prevents marring of the wood surface.
