Door furniture

For a plant access door with no external entry an internal hasp and staple and dropbolts are recommended.
If panic escape is required a full width panic bar or push pad can be fitted with external entry via Sunray 6000 hasp and staple.
For increased security a 3-point locking system with padlockable handle can be used.
Other variations may be provided on request.


Non-standard sizes can be manufactured to suit site requirements (see chart opposite).
Single doors can be right or left hand hung.
Double doors can be right or left hand active leaf.
Clearances are deducted in manufacture to ensure fit.
If the threshold is not sitting on the slab edge, a step of 150mm will be required (with angle frame option).
