These rugged cages exceed MS UK Blue Book minimum requirements. The National cages all follow a common six-point design with crossed door bars and harness tubes for the driver and co-driver. All mandatory tubes are 45 x 2.5mm CDS as the MS UK require. National kits include a full set of footplates.
As a weld-in only cage the National cage is suitable for hillclimbing, racing and rallying where compliance to MS UK regulations is required.
