Frequently asked questions
How does this sign differ from the 'Do Not Obstruct Do Not Keep Open' version?
Both enforce fire door safety, but this version carries a single message. Choose the simpler variant if your facility policy emphasises obstruction prevention; use the longer message if you also want to prevent propping open.
What mounting method works best on a wooden fire door?
Pre-drilled Colorbond or polypropylene with stainless steel screws is ideal for wood doors. Alternatively, use a vinyl decal if you prefer a non-penetrating method, though screwed mounting offers greater security and longevity.
Do reflective upgrades work in smoky conditions?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
What are the lead times for bulk orders?
Automatic volume pricing is 5–9 signs: 8% off, 10–24 signs: 15% off, 25–49 signs: 24% off, 50–99 signs: 32% off, 100+ signs: 40% off. The configurator is the source of truth and updates the unit price as quantity changes.
Can I order both this sign and the extended message version for different doors?
Yes. Many facilities use the simpler 'Do Not Obstruct' sign on standard fire doors and the extended version on high-traffic or multi-purpose doors. Mixed orders receive the same trade bulk pricing.
