Introduction to the RGL Shrouded Surface Back Box (PBBSHRGN)
RGL PBBSHRGNis a compact, shrouded surface back box engineered to house standard exit/egress push buttons and to provide conduit entry for cabling. With an external footprint of approximately 90 mm \u00A0 (approx.) and a main internal depth of 40 mm, the unit includes a shroud that projects to around 50 mm to accommodate thicker components and stainless-steel faceplates. Constructed from high-impact plastic and finished in green, the PBBSHR-GN is intended for surface-mounted access control and egress installations where a standard pattress box is too shallow.
Key Features at a Glance
- Shrouded design for additional internal depth (40 mm main depth; shroud ~50 mm)
- External footprint approx. 90 (fits 85 ) stainless steel plates
- Conduit entry provision for tidy, code-compliant cabling
- Durable high-impact plastic construction; green finish for visibility
- Compact surface-mount design ideal for retrofits and new installs
Detailed Specifications and Practical Benefits
Understanding the technical specifications of the PBBSHR-GN helps explain why it is a practical choice for many access control and egress installations. Below are its core technical details with an explanation of the practical benefits each delivers.
- Dimensions:90 mm (external footprint): compact profile that fits standard 85 mm plates)
- Main depth:40 mm. Provides sufficient room for common exit/egress push button assemblies and wiring without crushing or folding cable, making installation faster and more reliable.
- Shroud depth:Approximately 50 mm. The shroud adds clearance for thicker stainless-steel faceplates and ensures that buttons and actuators sit correctly and flush with the plate.
- Plate compatibility:Designed to accept standard 85 mm stainless-steel plates; useful for installers who prefer durable metal faceplates for heavy-use locations).
- Conduit entry:The design accommodates conduit entry, enabling neat cable routing and adherence to many local wiring standards. This is important in commercial installations and where cables must be protected.
- Material and finish:High-impact plastic provides a lightweight yet robust enclosure that resists knocks and scuffs. The green finish is often chosen for visibility and to match safety-related equipment aesthetics.
Use Cases and Installation Scenarios
The PBBSHR-GN is focused on access control and egress applications where surface mounting is necessary or preferred. Its extra internal depth and shrouded profile make it particularly effective in the following scenarios:
- Surface-mounted egress buttons:Where a wall is solid concrete or tiled and flush back boxes are impractical, the PBBSHR-GN allows easy surface mounting of exit buttons and keeps wiring tidy with conduit entry.
- Access control panels:Small access control systems often require a neat enclosure for push buttons or key switches. The box fits behind standard 85 mm plates and leaves room for wiring and terminals.
- Retrofit projects:In upgrades where previous boxes are too shallow for modern assemblies, the shrouded back box provides the extra depth needed without major wall work.
- Industrial and commercial locations:The high-impact plastic resists damage from everyday knocks in busy corridors, factories, or loading bays while the green colour helps operators quickly identify egress controls.
How It Compares with Similar Products
When comparing the PBBSHR-GN to other back boxes, consider depth, material, plate compatibility, mounting style, and conduit options.
- Standard pattress/back boxes:Typical pattress boxes are shallower and may not accept thicker faceplates or leave enough room for wiring. The PBBSHR-GN offers the extra depth and the shrouded profile to solve that problem.
- Metal back boxes:Steel or stainless boxes are more robust and sometimes offer higher ingress protection or fire rating, but they add weight, cost, and potential corrosion concerns. The PBBSHR-GN is lighter and lower-cost while still durable for many indoor and sheltered uses.
- Deep waterproof enclosures:For outdoor and harsh environments you may need an IP-rated box. The PBBSHR-GN is ideal for indoor and sheltered outdoor use but you should confirm IP rating and compatibility if weatherproofing is required.
- Specialist anti-vandal boxes:Anti-vandal enclosures are recommended in very exposed public areas; the PBBSHR-GN is a good choice for many commercial and industrial indoor uses but may not replace purpose-built anti-vandal solutions.
Customer Feedback and Installer Notes
While there are no formal published reviews included here, typical installer feedback for products like the PBBSHR-GN tends to focus on: ease of fitting standard 85 and tidy conduit routing. Representative comments might read:
- "Good depth for stainless plates— makes installs simple and neat."
- "Robust for a plastic box and the green finish helps on safety doors."
- "Conduit entry is a real time-saver on commercial jobs."
These sample remarks reflect common priorities: fit, finish, and installation efficiency. As with any electrical installation, users should ensure compliance with local codes and have installations completed or inspected by a qualified electrician.
Conclusion: Why Choose the PBBSHR-GN?
The RGL PBBSHR-GN shrouded surface back box is a focused, practical solution for installers and specifiers who need a compact surface-mounted enclosure with extra internal depth. Its key strengths are the shrouded design that accommodates 85 stainless plates, conduit entry for tidy cabling, and a durable high-impact plastic body. Priced affordably with a suggested retail price of (suggested price : ), it represents a cost-effective component for projects that need a reliable, compact solution.
Before specifying or ordering, check any site-specific requirements (such as IP rating, CE/UKCA marking, or compatibility with particular faceplates) with the manufacturer or reseller. If installation involves mains wiring or modifications to safety circuits, have the work carried out by a qualified electrician and verified against local regulations.
