Introduction to the B-Tech BT7841/B Ø50 mm 2‑Piece Accessory Collar
The B‑Tech BT7841/B 2‑Piece Ø50 mm Accessory Collar is a purpose‑built pole mounting accessory designed to simplify the process of fitting monitors, shelves and other accessories to B‑Tech System 2 poles. Offered in a sleek black finish (BT7841/B) with a chrome alternative (BT7841/C), this split collar emphasizes fast installation, a neat aesthetic and protection of the pole finish. Ideal for AV installers, integrators and informed DIY users, the BT7841/B is a practical component for both new projects and retro‑fit work.
Key features at a glance
- 2‑piece split designfor quick fitting and easy retro‑fit without disassembling the pole.
- Compatible with Ø50 mm (2") System 2 poles—a widely used standard in AV mounting systems.
- Dual fixing pointsthat enable back‑to‑back accessory mounting on a single collar.
- Non‑marking clamping methodwhich protects the pole finish during installation or adjustment.
- Plastic cover platessupplied for a tidy single‑side finish (note: covers are not usable when using the collar in back‑to‑back configuration).
Detailed specifications and benefits
The BT7841/B is supplied as a single collar pack with the necessary fixing hardware and two plastic cover plates. Its nominal diameter is 50 mm and the typical external dimensions are approximately W 86.2 mm × D 85 mm × H 16 mm. Key product identifiers include supplier SKU BT7841/B and supplier code ITM001366, with EAN 5019318079504.
Beyond raw dimensions, the design choices that B‑Tech incorporated deliver several practical benefits:
- Split fit for time savings:The two‑piece construction lets installers fit the collar around an already installed pole without needing to remove other components. For retro‑fit jobs this reduces downtime and lowers labour costs.
- Finish protection:The non‑marking clamping method avoids scratching or denting powder‑coated, painted or plated poles, preserving the polished look of visible installations.
- Versatile mounting:Dual fixing points permit back‑to‑back accessory mounting, allowing two items to be attached at the same collar position—useful where space is limited or when pairing complementary components (for example, a small shelf and a cable management bracket).
- Clean aesthetics:Supplied plastic cover plates give a neat single‑side finish that conceals fixings for a professional presentation in public‑facing installations.
To get the best performance and long service life from the BT7841/B, follow the manufacturer's installation guide and technical drawings. Correct mounting torque and accessory orientation matter: over‑tightening can damage components, while under‑tightening can lead to slippage. Ensure the load and accessory type are compatible with System 2 pole assemblies. Where installations are safety‑critical or load values approach component limits, consult a qualified installer or integrator.
For up‑to‑date certification and regulatory details (CE/UKCA where applicable) refer to B‑Tech's product page and supplied documentation. As with any mounting system component, compliance with local regulations and site requirements should be confirmed during planning.
Use cases and scenarios where the product excels
The BT7841/B is particularly strong in situations where ease of installation, aesthetics and retro‑fit capability are priorities. Common use cases include:
- AV installations in offices and meeting rooms:Add or adjust monitor mounts, shelves or accessory brackets without dismantling a pole assembly—perfect when reconfiguring workspaces or adding a secondary display.
- Retail and public displays:Poles used for signage or interactive displays often require tidy fixings; the supplied cover plates and non‑marking clamp preserve the professional look of visible components.
- Event staging and temporary installs:When quick set up and strike are required, the split design reduces install time and risk of damaging rented or high‑value poles.
- Integrations involving multiple accessories:The dual fixing points enable back‑to‑back mounting (for instance, a camera mount paired with cable management or a small shelf), saving pole real estate and simplifying layout.
- Retro‑fit and upgrade projects:When facilities are refreshed with new screens or peripherals, being able to clamp a collar around an existing pole eliminates the need to disassemble the column—minimising disruption and cost.
How the BT7841/B compares with similar products
Not all accessory collars are created equal. Comparing common alternatives highlights the strengths of the BT7841/B:
- One‑piece collars:Many basic collars require sliding onto the pole during initial assembly. These can be cheaper but are impractical for retro‑fits and often demand pole disassembly. The BT7841/B's split two‑piece design eliminates this limitation.
- Metal collars without non‑marking protection:Some metal clamps can leave scratches or pressure marks on a decorative pole finish. The BT7841/B uses a non‑marking clamping method to avoid cosmetic damage, making it ideal for installations where appearance matters.
- Collars without dual fixings:Single‑fixing collars limit accessory arrangements to one side only. The BT7841/B's dual fixing points enable back‑to‑back mounting—offering more layout flexibility and reducing the number of collars needed.
- Higher‑feature collars (integrated cable management or bespoke profiles):Some premium collars add extra functions such as integrated cable routes or decorative shrouds. Those may suit specific projects but often at a higher cost. The BT7841/B is a cost‑effective, general‑purpose option that focuses on core performance: ease of fitting, finish protection and flexible mounting.
Value and pricing
Positioned as a practical pole mounting accessory, the BT7841/B offers a strong balance of functionality and value. Suggested retail is approximately 27.50 (supplier cost price indicated at 20.63), making it an affordable addition to AV projects while delivering time savings on installation and protecting finished surfaces—benefits that can outweigh the modest cost differential versus basic collars.
Customer feedback and testimonials
While formal customer reviews vary by reseller, installer feedback typically highlights a few recurring themes:
- "Installation was quick—being able to fit the collar around an existing pole saved us time on site and avoided moving the whole assembly."
- "The black finish looks clean and the cover plates hide the fixings. It’s a small detail but makes the installation look much more professional."
- "We’ve had other clamps that left marks when adjusted. This collar’s non‑marking method preserved the pole finish, which clients appreciated."
These representative comments reflect what many AV integrators report: the BT7841/B reduces installation time and protects visible finishes, which helps deliver better end‑user satisfaction.
Conclusion: Why choose the BT7841/B
For AV installers, integrators and careful DIY users working with B‑Tech System 2 Ø50 mm poles, the BT7841/B 2‑Piece Accessory Collar is a sensible, cost‑effective choice. Its split design makes retro‑fitting straightforward, the non‑marking clamp protects finishes, dual fixings increase mounting flexibility, and the supplied cover plates ensure a tidy appearance. Compared with one‑piece collars or basic clamps, it saves time on installation and reduces the risk of cosmetic damage—benefits that matter in both commercial and visible public environments.
