No Admittance Authorised Personnel Only Acrylic Signs help you stop unauthorised entry at doors, corridors, plant rooms and controlled workspaces. The red prohibition symbol and clear wording guide staff, visitors and contractors before they step into restricted or higher-risk areas.

Where No Admittance Acrylic Signs Should Be Positioned

You should install this sign at eye level on doors, beside access points or at the start of restricted corridors. It works best before the decision point, so people understand the entry rule before opening a door or walking into a controlled workplace area.

Viewing Distance Guide for Clear Access Control

Choose the size by how soon people need to read the instruction. Use smaller signs for close doorways and larger formats where people approach from corridors, receptions or wider work areas.

Size option	Practical viewing guidance	Best use
H 210 x W 148 mm	Close reading up to around 5 metres	Small doors, cupboards and staff-only rooms

H 420 x W 297 mm	Stronger recognition up to around 15 metres	Busy entrances, warehouse routes and larger interiors

ⓘ Installation Guidance

Practical Fitting Advice for Restricted Access Acrylic Signs

❌ Placement mistakes to avoid

❌ Do not fit it too low where handles, trolleys or furniture can block the message.

❌ Do not place it behind glass reflections that make the red symbol harder to see.

❌ Do not install it after the restricted doorway where the instruction arrives too late.

❌ When this sign is not the right choice

❌ Do not use it outdoors unless the chosen fixing location protects the acrylic properly.

❌ Do not rely on it alone where locked access, supervision or permit control is required.

❌ Do not use it for emergency escape information or mandatory PPE instructions.

✅ Better installation choices

✅ Fit it at normal eye height before the person reaches the door or threshold.

✅ Use the larger size where people approach from long corridors or open work areas.

✅ Keep surrounding walls uncluttered so the prohibition symbol is not visually competing.

? Customers Questions

No Admittance Authorised Personnel Acrylic Signs questions answered

What are No Admittance Authorised Personnel Only Acrylic Signs used for? They help you restrict access to rooms, corridors and entrances where only approved staff, contractors or trained personnel should enter.

Is acrylic the right choice for a front-of-house area? Yes. Acrylic gives you a more polished finish than standard plastic, making it suitable for receptions, offices, clinics, schools and managed workplace interiors.

Where should I fit this sign? Fit it directly on the door, beside the handle side or immediately before the access point so people see the instruction before entering.

Does the sign come with fixings? Yes. It is pre-drilled and supplied with a fitting kit, with fixings designed to hold the sign around 20mm proud of the wall.

Which size should I choose for a restricted entrance? Use H 210 x W 148 mm for close door viewing, H 297 x W 210 mm for normal corridors and H 420 x W 297 mm where people approach from farther away.

Smart restricted access sign comparisons

For a simpler non-acrylic alternative, choose standard authorised personnel only signs where function matters more than finish. Suitable for service rooms, stores and staff-only doors.

If you need the same wording across several areas, use authorised personnel sign packs for repeated access points. Good for multi-door layouts and managed facilities.

For a broader access refusal, compare no access prohibition sign packs where the message should be direct. Useful for barriers, plant rooms and restricted workspaces.

Where pedestrians must be kept away from a hazard, consider pedestrian access prohibition warning signs instead. This gives a more specific walking restriction for unsafe approaches.

To compare access wording and formats, browse restricted access and no pedestrian signs before choosing your final sign. This helps you balance appearance, location and message strength.
