Entrance & Security Doors: Single, Unequal & Double
Entrance and security door selection for distributors and contractors. Compare single, unequal double and double doors, opening sizes, materials and locks.
An entrance door is an assembly of a leaf, frame and hardware at a building entrance. Selection should account for access space, opening direction, installation conditions and locks. TEENPAI lists single doors, unequal double doors, double doors and selected combinations with transoms; availability depends on the model and agreed configuration.
Choosing a single, unequal double or double door
A single door uses one active leaf. An unequal double door combines a larger and smaller leaf for everyday access and occasional wider passage. A double door uses two leaves. Start with the opening and access requirements, then check the model-specific size matrix rather than judging fit from a photograph.
Opening dimensions and product dimensions
Provide the site opening width and height, required outside frame dimensions, wall thickness and threshold requirements, with units. A catalogue height-by-width entry is not automatically the required site opening. Installation allowances must be confirmed with the installer and export sales.
What to check in a security entrance door
Review material, sheet thickness, frame construction, lock body, cylinder, hinges and installation method. A smart lock is a configuration choice, not a substitute for verification of the complete door assembly. Specify any required security standard and model-specific test evidence before ordering.
Configurations for your market
Distributors can build ranges around door types, finishes and locks. Contractors should prepare quantities and handing by building or batch. Confirm private-label branding, non-standard sizes and other requirements in the drawings and quotation.
Buying questions
How do I select entrance doors for a project?
Prepare opening and size schedules, handing, lock requirements and acceptance criteria, then shortlist models using published specifications. Price and timing depend on the confirmed configuration.
Will any double door fit a wider opening?
No. Check the selected model’s available sizes and frame requirements rather than relying on the door-type name.
Are these fire doors?
Do not treat ordinary entrance doors as certified fire doors. Share the required standard and rating so export sales can verify whether a suitable product and evidence are available.
