Why specify NX-R

Round covers are what most chambers need. This series is built around four details that decide whether a cover survives ten years of traffic.

Non-through lifting hole — operated with a standard T-key, cannot be hooked out of the frame.
Clamshell frame geometry — resists levering, which is how most theft attempts actually start.
Shock-absorbing rubber ring — silent under traffic, no rock in the frame, no rattle failures at inspection.
Diamond tread pattern — grip on wet and oily surfaces; relief depth up to 3 mm can be customised.
Moulded EN 124 marking — class, nominal size and your utility logo are in the tool, not painted on.
