Manufactured from clear, durable acrylic, it offers excellent optical clarity while remaining significantly lighter than glass, making it easy to handle, install and integrate into bespoke designs.
Available in a wide range of diameters and flange sizes, this dome is well suited to retail merchandising, exhibition stands, product protection, lighting features and architectural models. Choose from no flange or several flange options to suit surface mounting, recess fitting or integration into enclosures, giving you a flexible solution for both functional protection and striking visual presentation.
Product Features
- Outside/inside diameter options from 100 mm, 150 mm, 200 mm, 250 mm and 300 mm, plus over 15 additional sizes to suit a wide variety of display and protection needs.
- Matching flange diameters including 96 mm, 146 mm, 194 mm, 244 mm and 294 mm, with a further 15+ flange sizes for precise mounting and fixing.
- Choice of no flange for seamless integration, or flanged rims of 20 mm, 25 mm and 40 mm for secure surface or recessed mounting.
- Manufactured from clear acrylic for high optical transparency and a professional, glass-like appearance.
- Lightweight yet durable construction, easier to handle and install than glass domes of similar size.
- Precisely formed hemispherical shape for consistent curvature and a uniform visual effect across all sizes.
- Suitable for machining and fabrication (such as drilling the flange), enabling custom fitting to frames, panels or housings.
Key Features and Benefits
- Enhanced product visibility thanks to the clear acrylic material, making it ideal for retail, exhibition and museum displays where contents must remain clearly seen.
- Reduced risk of breakage compared with glass, providing a safer and more robust protective cover for equipment, models and merchandising.
- Lightweight design lowers installation effort and support requirements, especially for ceiling, wall or stand-mounted displays.
- Multiple diameter and flange options allow you to select a dome that closely matches your existing apertures, frames or enclosures, minimising additional fabrication work.
- Easy to clean and maintain, with a smooth surface that can be wiped down to keep displays looking clear and professional.
- Highly versatile for custom applications, from interactive installations and sensor covers to decorative lighting features and architectural mock-ups.

Frequently Asked Questions
Can this acrylic dome be drilled or machined for fixings and custom mounting?
Yes, the acrylic dome can typically be drilled on the flange area using appropriate tools and techniques for plastics. It is advisable to use sharp drill bits, low feed rates and to support the material well to reduce the risk of cracking. If you are unsure, testing on an off-cut or seeking advice from a fabricator is recommended.
Is the acrylic dome suitable for outdoor use?
Acrylic offers good weather resistance and can be used outdoors; however, long-term exposure to sunlight and harsh conditions may affect appearance over time. For external applications, ensure the dome is securely mounted, regularly cleaned and inspected, and consider specific environmental requirements such as UV exposure and temperature changes.
How do I choose the right flange option for my application?
If you plan to sit the dome over an opening or recess and secure it mechanically, a flanged option (20 mm, 25 mm or 40 mm) is usually best, as it provides a flat surface for fixing and sealing. If you intend to bond the dome into a structure, embed it, or use a custom frame that holds the edge, a no-flange version may offer a cleaner, more seamless finish. Measure your aperture carefully and select a flange size that gives enough overlap for secure fixing.
