Pre Installed High Security plate
The R&B Sentinel is designed for seamless integration, offering the capability to be pre installed to any cover within our extensive range. This ensures a fully secured access chamber immediately upon installation, providing peace of mind from day one.
To accommodate varying security protocols, each plate is expertly prefabricated with a dedicated padlock facility. Furthermore, the unit offers versatile locking configurations; it can be specified with standard, Torx pin, or ultra-high security screws, allowing the final product to be precisely tailored to meet specific customer requirements and risk profiles.

RETRO-FIT SECURITY
The SENTINEL range can be designed and installed for any existing chamber regardless of how long it has been installed. Our team can arrange to measure bespoke fabrications or work from site drawings. Data security is becoming increasingly prevalent with multiple attacks recorded last year causing costly repairs and potential breaches in networks.

IMPACT DUCTILE IRON RANGE
When your project demands uncompromising strength, the Sentinel system delivers. By pairing Sentinel technology with our IMPACT range of ductile iron covers and frames, we’ve created a solution engineered for the most demanding environments.
The IMPACT range isn’t just heavy-duty—it’s the toughest in our stable. Manufactured to be significantly heavier and more durable than any other range produced by R&B UK JT LTD, it provides an unparalleled foundation of stability and wear resistance. When you choose Sentinel and IMPACT, you aren’t just installing a cover; you’re investing in long-term site integrity.
