The installation of black stealth door locks has clear requirements for the thickness and material of the door. Comprehensive judgment should be made based on structural stability, installation compatibility and usage scenarios. Specific requirements are as follows:
I. Requirements for Door Body Thickness
Standard range
The thickness of the door with invisible door locks is generally 45-60mm, of which 45-47mm is the optimal optimal process range.
45mm thick: Common material in standard stealth door design, square steel structure with front and rear exposure of 9mm +25mm for balance, weight loss and stability.
50-60mm thick: suitable for high strength or sound insulation (e.g. entrance doors), interior can be filled with aluminum honeycomb material to enhance structure.
Thickness less than 45mm: may lead to unstable lock installation, long-term use of the door may not close, deformation and other problems.
If the thickness is more than 60mm: It's important to make sure the lock supports it (for example, smart locks may require special specifications), otherwise you'll need a custom lock core or square bar.
Special scene adaptation
Compatibility of smart locks: To install smart stealth locks, doors should be between 35-120mm thick, but 45-60mm is the most common range of compatibility.
Old door renovation: For old or non-standard wood doors less than 45mm thick, external locks or electronic locks need to be installed to modify, otherwise it will affect the stealth effect.
II. Portal material requirements;
Recommended material
wooden doors;
It has the best compatibility, is easy to drill and install, and adds a modern feel with a sharp contrast to the black lock.
It is recommended to choose solid wood composite doors or fireproof and flame-retardant boards filled with aluminum honeycomb for greater stability.
Metal doors (steel/aluminium alloy)
To choose a special metal door lock mechanism to avoid hard material and difficult to open holes or loose.
Black lock body paired with matte metal doors for industrial or minimalist style.
Glass doors
It is only suitable for single or double laminated glass with a thickness of 8-12mm and requires special glass fixtures or embedded locks.
Black lock body and a black glass frame create a unified visual look, perfect for study or balcony scenes.
Bunker materials;
Fire doors: Make sure locks are the fireproof certification. The structure of stealth lock is complex, which may affect the fire performance.
Dense slab doors: If the internal structure is held together by three 18mm panels, excessive weight may cause door deformation and should be avoided.
III. Installation Details and Process Requirements
Punching accuracy
Professional tools,such as a hole openers, should be used to ensure the verticality of the lock and prevent it from being installed askew.
Smart locks need to measure the size of the lock in advance (such as the width of the guide plate and the distance between the door gaps) to prevent installation failure.
Hardware options;
It is suggested that the invisible door be hydraulically hinged in order to avoid the condition that the common hinges cannot meet the requirements of the one-sided lock.
For smart locks, it is necessary to determine whether the top and bottom hooks are compatible. Some brands,such as Philips, support automatic locking but need to remove the top and bottom hooks to extend service life.
Structural reinforcement
For doors ≥ 50mm thick, it is recommended to add aluminum honeycomb material in the middle to prevent deformation after prolonged use.
Wooden doors should be OSB leveled at the opening position to ensure that the doorframe is flush with the wall.
IV. Style Matching Suggestions
Modern minimalism: Black lock body + white/grey door panel + handleless design, accentuating simple lines.
Industrial Style: Black lock body + metal door + open lock structure to retain the original texture.
luxury style: black lock body + walnut door + brass lock embellishment to enhance luxury.
