Mortise latch brass / stainless steel (304) | GSV-No. 3234
2. February 2019The strike plate for brass mortise locks with latch and deadbolt, GSV-No. 3226, is a precisely engineered component designed to ensure secure and reliable door closure. Manufactured entirely from solid brass, it offers excellent durability, corrosion resistance, and mechanical strength, making it suitable for long-term use in both residential and commercial applications. The brass material not only provides functional stability but also contributes to a visually appealing finish that complements a wide range of door hardware and architectural styles.
The strike plate is designed to accommodate both the latch and the deadbolt of a mortise lock, providing accurate alignment and smooth engagement of the locking elements. This ensures reliable operation, prevents undue wear on the lock components, and maintains consistent security over time. The standard length for the lip of the strike plate is 29 mm, which is compatible with most conventional mortise locks and door configurations. For specialized installations or non-standard requirements, other lengths are available on request, allowing for flexible adaptation to specific architectural or functional demands.
The precise machining of the latch and deadbolt openings ensures optimal fit, reduces friction, and allows smooth locking and unlocking of the door. The solid brass construction also provides sufficient strength to withstand repeated mechanical stress and daily use without deformation, ensuring long-lasting performance.
Overall, the strike plate GSV-No. 3226 combines robust material properties, precise engineering, and versatile sizing options to deliver a technically reliable solution for secure door locking. Its durability, functional accuracy, and adaptability make it an ideal choice for both standard and customized door systems.

The hand of door for mortise locks is defined as:
if the door is closed and the hinges are visible on the right/left, then the door is right/left hand. The door is therefore hinged on the right/left and according by definition of DIN right/left.
Or: if you grasp the handle with your right hand and latch and deadbolt show to the left, then it is right hand. If you grasp the handle with your left hand latch and deadbolt show to the right, it is a left hand.

Rim locks
The hand of door for rim locks is defined as:
if the door is closed and the hinges are visible on the right/left, then the door is right /left hand. The door is therefore hinged on the right/left and according to the definition DIN “right/left".
In addition to the designation “left” and “right”, it is to be indicated whether the locks are intended for inward or outward opening doors.

Sliding door mortises
The hand of door for sliding door mortises is the same for right and left. Sliding rim door locks different for left and right doors.
When ordering, always indicate “left” or “right”.

Latch
The lock latch keeps the door shut. In order to open the door, it must be retracted. |
Type of latch design | Illustration |
single latch | ![]() |
anti-vibration or three-piece latch | ![]() |
rolling latch adjustable | ![]() |
POM-latch for strike dampening | ![]() |
Deadbolt
The deadbolt regulates the access rights through the turning motion of the cylinder by key. The deadbolt is being driven out or retracted through the turning motion. |
![]() |
Faceplate
The faceplate is the visible part of the lock case. The faceplate, the latch and the deadbolt are the only visible parts of a mortise. |
![]() |
Handle hub
The handle hub takes the square spindle of the handle in order to retract the latch inside the lock through the turning motion of the same. This process allows the opening of the door. The shipbuilding norm specifies a 9mm square with a 2° incline. Schwepper supplies also with 8mm square, special contour or 0° incline on request. |
![]() |
WC-/privacy hub
The WC hub takes the square spindle of the olive or thumb turn, that retracts or drives out the deadbolt from the inside - analogue to the turning motion of the cylinder. The shipbuilding norm specifies a 7mm square. Schwepper supplies also with 8mm square on request. |

Dimension | Illustration | |
Backset
The backset is the distance from the front edge of the faceplate to the center of the cylinder hole respectively handle hub square. The rear backset behind the center line remains always 27mm. |

Distancing
The distancing is the dimension from the center of the handel hub and the center of the hole for profile cylinder / privacy (WC) / key. The industry standard in shipbuilding is 75mm. |

Latch protrusion
The latch protrudes according to the industrial DIN standard in shibuilding 14mm. Other technical standards for latch protrusion are: 16 mm according to DOT (Department of Transportation) 19 mm according to USCG (US Coast Guard) |
