A vehicle rollguard comprising at least one member of stanchions and struts which are detachably connected. The connections include a necked-down end of one of the interconnecting members and an opening in the other interconnecting member for receiving the necked-down end. The opening in the interconnecting member can be in the sidewall or be an open end. Pairs of opposed aligned apertures in each interconnecting member form a passage for a bolt or other securement means. Securement to a vehicle includes a bracket in the form of a plate having openings for bolting to a vehicle and a pair of upstanding tabs having opposed aligned apertures. Another pair of opposed aligned apertures on the end of the rollguard member to be secured line up with the apertures in the tabs for passage of a bolt or other securement means. A disc of hard plastic overlies the plate and is disposed between the bracket and the end of the rollguard member to be secured.
