Bundle Guide — What Else Do You Need?
A complete door set depends on the door material, the function required and whether it is a double door.
Double doors need flush bolts to secure the inactive leaf. Doors under 2100 mm: a 150 mm bolt top and bottom. Doors 2100 mm and above: a 300 mm bolt top and 150 mm bottom. Flush bolts are available non-lockable or key-lockable.
Hinges — Which One Do You Need?
| Hinge type | Best for | Why |
|---|---|---|
| Ball bearing | Entrance and heavier doors | Bearings reduce friction and wear — best for high-use doors. |
| Fixed pin | Internal and lighter entrance doors | A reliable all-rounder for most internal applications. |
| Loose pin | Internal use — ideal for bathrooms | The pin withdraws so the door lifts off without unscrewing the hinge. |
| Parliament | Doors that must open 180° | Projects the door clear of the frame or architrave so it swings back against the wall. |
Three hinges per door is standard for internal and entrance doors.
