Description

The M2 / SM2 Pedestrian Guardrail is a trusted and economical solution for enhancing roadside safety in high-traffic pedestrian zones. Featuring a distinct sight gap or "letterbox" panel, it improves visibility between pedestrians and drivers while directing foot traffic toward controlled crossing points.

This guardrail is widely used by local authorities throughout the UK and is ideal for placement outside schools, near car parks, and across busy highways. Manufactured as a robust, single-piece panel with either inline (M2) or staggered (SM2) vertical infills, it requires no separate posts and can be fabricated to follow slopes or curved routes. Available in galvanised finish or with black and green powder-coated options, each unit comes with complete fixings and conforms to BS 7818.
