Double Swing Height Restrictor for two-lane sites The Double Swing Height Restrictor is a fixed steel barrier that spans two carriageways to stop high-sided vehicles bypassing a single-lane restrictor. Each restrictor gives 2.2m of clearance, reducing to 2.05m with an optional knocking bar fitted, and the booms swing open and lock on catch posts when full-height access is needed. Made in the UK from galvanised mild steel, it is available in five lengths, fixed by ragged (concrete-in) or flanged (bolt-down) posts, and finished in galvanised steel as standard or powder-coated to any of seven RAL colours. Key features Spans two lanes - stops vehicles bypassing the restriction by using an adjacent carriageway. 2.2m clearance - reduces to 2.05m with an optional knocking bar fitted. Swings open for access - booms open and lock on catch posts when full-height vehicles need to pass. Ragged or flanged fixing - concrete-in for a flush finish or bolt-down for surface mounting. Made in the UK from galvanised mild steel, powder-coatable in 7 RAL colours. Five lengths - 6m, 8m, 10m, 12m or 14m, to suit the carriageway width.
